Belimo ZoneTight Zone Valves
Overview
Designed for maximum efficiency in tight spaces, Belimo’s ZoneTight valve offering sets new design and performance standards for
both pressure dependent and pressure independent zoning applications.
ZoneTight Zone Valve (QCV)
The ultra-compact QCV leads the way in Belimo’s new generation of room and zone solutions. Equipped with a space-saving 2-way or
3-way ball valve and an electronic rotary actuator, the QCV has an installation height of just 4.33 inches (110 mm) and offers a number
of benefits over conventional pressure dependent control valves, including:
•
Belimo ball valve design with zero leakage eliminates energy loss.
•
Self-cleaning ball valve technology provides superior clog resistance.
•
Low power consumption up to 95% less than conventional zone valves.
•
Field adjustable Cv value to meet your design requirements.
ZoneTight Pressure Independent Zone Valve (PIQCV)
The PIQCV offers all the advantages of a Pressure Independent
Characterized Control Valve (PICCV) but in an ultra compact
configuration. The PIQCV combines a differential pressure regulator
with a 2-way control valve to supply a specific flow for each degree
of ball opening regardless of system pressure fluctuations. The valve
performs the function of a balancing valve and control valve in one unit.
•
Smallest pressure independent characterized ball valve in the market.
•
Actuator runs at 0.3 W saving energy and transformer power.
•
Flow is adjustable at the actuator and always perfectly balanced.
•
Permits PIV installation in tight spaces.

Belimo ZoneTight Zone Valves
Features
ZoneTight Features
Compact Design
When faced with limited available mounting space, the Belimo ZoneTight valve’s super-compact design helps
maximize workable space and complements OEM valve compartment optimization.
Ball Valve Technology
Unlike short stroke globe valves with plug and seat design, the self-cleaning ball helps minimize energy losses
caused by clogging (0% A to AB leakage) and eliminates seat leakage. The intuitive configuration also allows
for bi-directional flow (QCV) unlike traditional paddle style zone valves. In addition, equal percentage flow
characteristic provides superior part load coil performance.
Actuator with Patented Brushless DC Motor
The brushless DC motor’s power consumption when running is a mere 0.3 W (0.2 W when holding) saving
energy and transformer power. In addition to significantly reducing energy costs, this helps eliminate failures
due to stalled motors and prolongs actuator life. It also allows for more units to be powered by a single
transformer.
Snap Fitting
The QCV and PIQCV easily connect to the actuator allowing operators and technicians to install valves quickly,
easily, and without the use of tools. This helps simplify commissioning, reduces labor costs and help reduce
inventory.
Field Adjustable Max Cv/Flow
QCVs and PIQCVs can be quickly and easily field adjusted to ensure that necessary design requirements
are met.
Tech.Doc - 04/15 - Subject to change. © Belimo Aircontrols (USA), Inc.
Stem Extension for Insulation
Unlike conventional zone valve actuators, which are normally covered by pipe insulation, the stem extension
on QCVs and PIQCVs allows for easy actuator removal without damaging the surrounding insulation, helping
simplify operation and maintenance activities.

Flow Pattern
QCV Flow Pattern
QCV 2-way valves can be piped with flow entering and exiting
either port.
For on/off control of coil flow the QCV 3-way valve can be piped with
the AB port connected to the supply or the return. For changeover
application, AB port can be piped to the coil.
INLET
OUT
OUTLET
TTLET
For a QCV 3-way switching application, pipe hot and cold supply
water to ports A and B and the appropriate seasonal supply water
will exit the AB port for regulation by another 2-way valve; typically
installed in the return pipe.

PIQCV Flow Pattern
The PIQCV consists of a differential pressure regulator and a
control valve. The control valve is throttled to match the flow
command of the control signal. The differential pressure regulator
holds the pressure drop across the ball of the valve. As system
pressure changes, the differential pressure regulator moves in
response to keep the flow stable. Pressure (P1) at the inlet PIQCV is
high and pressure (P3) at the outlet is low. The differential pressure
between (P1) and (P3) must be between 5-50 to achieve pressure
independent flow. When differential pressure increases
the regulator opening is decreased. When differential pressure
decreases the regulator opening is increased. This allows for the
constant pressure differential across the ball of the valve.

Adaption for Proportional Actuators
For actuators with analog 2-10 VDC signal, after flow capacity adjustment has
been field-set by moving the clip to a desired position, execute the adaption
routine to scale the signal across the available travel. The actuator will travel
first in one direction and stall, then will travel in the opposite direction and
stall. Then it will travel to the commanded position of the control signal. When
the actuator is powered for the first time the adaption routine will execute
automatically. Execute the adaption function any time the clip position is
changed. The adaption routine does not change the actuator speed, which is
75 seconds over 90 degree rotation.
Adaption
For actuators with On/Off or Floating Control input there is no adaption
function or button.
Proportional Actuators: CQB24-SR, CQB24-SR-L, CQB24-SR-R, CQKB24-SR,

Flow Verfication
Mechanical PIQCV Pre-Flow
Verification Checklist
After the actuator travel limit clip has been correctly located to position
1-7 (or removed) to match the maximum flow setting of the coil, the
following procedures detail the flow verification and commissioning
procedures for Pressure Independent Valves Quick Compact Valves
(PIQCV). These procedures are not mandatory to ensure proper
operation of PIQCV. PIQCVs are very different from pressure dependent
control valves (standard control valves). Pressure variations in the
system do not affect flow through the PIQCV. Additional flow regulating
devices (e.g. circuit setters and automatic flow limiting devices) should
not be used in conjunction with PIQCVs. This makes the Testing and
Balancing (TAB) or commissioning process much different from
standard control valves. PIQCVs offer numerous maximum design flow
values in each valve body size. It is important to note that the valve will
travel to 90 degrees only when there is no end stop.
External P/T ports allow for independent verification of proper PIQCV
operation. Additionally, these ports allow for future comprehensive
troubleshooting and diagnosis. For proper and accurate flow
verification of the mechanical PIQCV, it is essential that the mechanical
contractor install P/T ports A, B & C as shown in Figure A if the
mechanical PIQCV body is not supplied with integrated ports. If the
PIQCV includes integrated PT ports the mechanical contractor only
needs to install P/T port A.
•
P/T port A and P/T port B (or A and P1) are used for measuring
pressure differential across the coil (used to measure water P to
equate to flow) or to measure water T across the coil.
•
P/T port B and P/T port C (or P1 and P3) are used to measure P
across the PIQCV assembly. PIQCVs must have 5 – 50 psid (11.5
ft. – 115 ft. H2O) (or per manufacturer’s specification) differential
pressure within this range. Do not manually remove the actuator
travel limit clip to fully open the valve to check for design flow
or pressure. Valve shall be commanded to design flow position
via analog or BMS (Building Management System) signal. The
required operating differential pressure range is necessary to
insure pressure independent operation of the PIQCV
•
Verify that system is purged of air and filled to proper pressure.
•
Verify that each PIQCV has the manufacturer’s required operating
differential pressure range across P/T ports B and C (or P1 and P3)
as shown in fig. A.
•
Verify proper pump operation per manufacturer’s specifications.
•
Verify proper supply water temperature is available and is at design
temperature.
•
Proper air filter maintenance has been completed.
•
Fan belts are in proper working order.
•
Heat transfer devices (coils) are clean.
•
Strainers are clean.
•
All manual shutoff valves are open.
•
All bypass valves are closed.
•
No automatic or manual balancing valves exist. If they do exist,
they must be set fully open and locked to not interfere with the
pressure independency function of the PIQCV.

1. Verify that the system is in proper working order. Depending on the
valves used, check the items listed for PIQCV Pre-Flow Verification
Checklists. Ensure that water is at design temperature.
1. Verify that the system is in proper working order. Depending on the
valves used, check the items listed for PIQCV Pre-Flow Verification
Checklists.
2. If diversity factor = 100%, command open all PIQCV’s via the BMS
system. Systems with less than 100% diversity need to have a
number of valves closed to match design diversity.
3. Ensure that pumps are either manually commanded to sufficient
speed to provide proper differential pressure across all valves OR
if pumps are under DDC pressure control ensure P setpoint is
sufficient to provide the above conditions.
•
Verify total system flow in main return line is at system design flow
rate using one of the following methods: Orifice, Venturi, Electronic
flow meter, System-level Flow Device
1. Decrease the pump speed (or decrease P setpoint if under
control) until a measureable flow decrease occurs.
2. Increase pump speed (or increase P setpoint if under control)
slowly until design flow is reestablished. Make note of the resulting
P. This will be the maximum system P operating setpoint.
Tech.Doc - 04/15 - Subject to change. © Belimo Aircontrols (USA), Inc.
Note: If total flow does not match design flow then troubleshooting
must be done to determine cause. This may involve verifying flows at
the terminal level.
Procedure #2 (Terminal Level Verification) – Air Delta T Method
Verification for PIQCV Cooling/Heating
1. Verify that the system is in proper working order. Depending on the
valves used, check the items listed for PIQCV Pre-Flow Verification
Checklists.
2. Ensure that water is at design temperature.
3. Ensure that terminal airflow is at design airflow rate (cfm).
4. Command open the PIQCV via analog or BMS control signal to
maximum design flow position. (Do not manually open the PIQCV
beyond the actuator travel limit clip position).
2. Ensure that terminal airflow is at design flow rate (cfm) or water
coil airflow is unencumbered.
3. Command open the PIQCV via analog or BMS control signal to
maximum design flow position. (Do not manually open the PIQCV
beyond the actuator travel limit clip position.)
4. Reference approved engineering document containing design
water temperature drop/rise for design conditions.
5. Measure water temperature differential of coil by using P/T ports A
and B (or A and P1) as referenced in Fig. A.
6. Measured temperature differential should be equal to designed
water temperature differential (EWT, LWT) as shown on the
contract documents.
Procedure #4 (Terminal Level Verification) – Coil P (Delta P)
Method
Verification for PIQCV Cooling/Heating
1. Verify that the system is in proper working order. Depending on the
valves used, check the items listed for PIQCV Pre-Flow Verification
Checklists.
2. Command open the PIQCV via analog or BMS control signal to
maximum design flow position. (Do not manually open the PIQCV
beyond the actuator travel limit clip position.)
3. Ensure P across valve assembly between P/T ports B and C (or
P1 and P3) as shown above in Fig. A is within manufacturer’s
operating parameters.
4. Reference approved engineering document containing design coil
water pressure drop (usually expressed in ft. of water) for design
flow conditions. This value will be for the heating/cooling coil
associated with corresponding PIQCV.
5. Reference approved engineering document containing design air
temperature drop/rise for design conditions.
5. Measure coil P by using P/T ports A and B (or A and P1) as
referenced in Fig. A.
6. Measure coil inlet air temperature and coil discharge air
temperature.
6. Formula to calculate flow is: Actual GPM = Design GPM x
7. Difference between coil inlet air reading (EAT) and coil discharge
air reading (LAT) should equal to or exceed design air delta T as
shown on the contract documents.
Note: Measured Coil P and Design Coil P must be expressed in the
same engineering units (feet of water, inches of water, psi, etc.).

VIII.C General Warranty Terms
8.3. Seller’s warranty may be null and void in the event of any:

with Client’s equipment, (c) use of Products in an unauthorized
manner, or (d) damage to Products not caused by Seller.
8.4. Client must promptly notify Seller of Products’ alleged
defect and provide Seller with other evidence and documentation reasonably requested by Seller. Before removing Products
from service, Client should contact a Seller-authorized support
technician by calling Belimo customer service. The contact
information for Belimo customer service is listed on the back
page of Belimo’s Product Guide and Price List (“PGPL”) or may
be found at www.belimo.com. Belimo customer service will
work with field technicians to troubleshoot problems. Many
problems can be resolved over the phone.
8.5. If a problem cannot be resolved over the phone, an RMA
number will be issued by Seller for return of the Products. Prior
to returning any Products under a warranty, Client must obtain
an RMA number from Seller, along with shipping instructions for
the return. The RMA number must be clearly written on the
outside of the box containing the returned Products. Only
Products returned to the proper location and identified with an
RMA number will be accepted by the Seller.
8.6. All returned Products should be packaged appropriately to
prevent further damage. Seller reserves the right to refuse any
returned material if improperly packaged or labeled (without an
RMA number). Products returned without proper RMA documentation will void Seller’s warranty.
8.7. Products found to be defective for which a warranty is
applicable will either be replaced or repaired at the Seller’s discretion. Seller is not responsible for charges that Client may
incur as a result of the removal or replacement of Products.
8.8. Repaired or replacement Products are shipped from Seller
via ground shipment. Other shipping methods are available at
the sole expense of the Client.
8.9. Repaired, replaced or exchanged Products will carry a warranty for a period of time equal to the greater of: (i) the remainder of the original 5-year warranty or 2-year warranty that was
applicable to the repaired, replaced or exchanged Products, or
(ii) six months, effective from the date the repaired, exchanged
or replaced Products are shipped by Seller (the “Replacement
Warranty Period”).
8.10. Advanced replacement Products for Products covered
under warranty may be obtained from Seller after the Belimo
customer service troubleshooting process has been completed.
For industrial products (such as butterfly valves), a purchase
order is required. The purchase order will be credited upon the
receipt and verification by Seller of the returned defective
Products. For non-industrial products, an invoice will be issued
and shall be due and payable if the returned Products are not
received by Seller within 60 days from the date that the replacement Products are shipped. Additional charges may apply if the
nature of the problem has been misrepresented by Client.
8.11. Both the conditional and unconditional warranties cover
the Products only, and do NOT cover labor associated with the
troubleshooting, removal or replacement of such Products.
8.12. New Products ordered in an attempt to circumvent the
warranty process may NOT be reimbursed if, upon receipt of
returned Products, it is determined that the defect in the
returned Products is actually field related, or the Products have
been returned for cosmetic reasons only.
8.13. Advanced replacement Products for butterfly valve actuators may not be new, but have been verified by the Seller for
electrical and mechanical operation. Such Products carry the
full warranty for the entire Replacement Warranty Period.
