DuraDrive
VB200R / VB210R & VB300R / VB310R Ball Valves
with MB3 and MB6 Series Actuators
Application
The DuraDrive VB210R and VB310R Series Ball
valves are Two-Way or Three-way, 1/2” or 3/4”
characterized control valves. The VB200R and
VB300R models are full port uncharacterised
valves for isolation and shut off.
The MB series actuators directly couple to the
valves using a unique quick,secure and simple
‘pop top’ connection. Actuators are available for
two-position, floating or proportional control
signals.
Typical applications include hot and chilled water
control in VAV reheat, fan coil units, and air handling units.

Application Note for Two-Way and Three-way Valves
© 2010 Schneider Electric. All rights reserved.
The VB210R and VB310R are are Characterized Control Ball Valves. They are designed so that flow
thru the A-port exhibits equal percentage flow (see Page 8). Thus, the A-port is the control port.
In a Three-way valve, the B-port is the bypass port. Flow thru the B-port is designed to be less than
that of the A-port. In most applications, this reduced flow compensates for the pressure drop that is
seen by the coil supplied by the A-port.
The VB300R and VB310R should only be used in Mixing applications, and not in Diverting applications

DuraDrive Ball Valves and Actuators
Function
The DuraDrive Ball Valves and actuator assemblies are designed for flow control based on the control signal input. The actuators are not intended for continuous use in zero dead band control systems.
Spring Return Actuators (all types):
When powered, the actuator moves to the desired position, tensioning the spring return mechanism. When power is removed
the actuator returns to the normal position as driven by the Spring Return mechanism. Actuator variants are available which will
either open or close a valve when the power supply is removed.
Proportional Actuators:
The control signal input and action is selected by means of the input signal jumpers on the actuator circuit board. All actuators
are shipped with the input signal jumper set for a 0 to 10 Vdc control signal and the control action jumper set for direct action
(DA; valve opens with an increase in control signal). Multiple actuators may be connected to a single controller. Do not exceed
the maximum current draw of the controller or transformer. When using a 4 to 20 mA dc control signal, a separate isolation
transformer must be used with each actuator.
Proportional Actuators perform a self-calibration cycle on power-up. The actuator will run to the open direction for approximately 20 seconds and then closed direction for approximately 2 ½ min (60 Hz) or 3 ½ min (50Hz). See Table-2 for exact timing.
Once this cycle is complete, the actuator will then accept and respond to the control signal.
Manual positioning of the actuator while power is applied is NOT recommended. If the actuator is manually positioned while
power is applied, the calibration cycle will need to be completed again for the actuator to function properly. To recalibrate the
actuator, cycle power off for more than 6 seconds.
Floating Actuators:
Spring Return and Non-Spring Return floating actuators with the time-out feature (‘T3’ in designation code) will automatically limit the running time of the actuator. The time-out feature automatically cuts off the control signal to the valve after three minutes
(see Table-1) of continuous operation. Upon change in control signal direction, the actuator will resume operation.
The controller or thermostat used to operate the Non-Spring Return Floating actuator must be configured to turn off the control
signal after being continuously on for three minutes. Multiple actuators may be connected to a single controller. Do not exceed
the maximum current draw of the controller or transformer.
The Spring return feature should not be used for routine, normal operation
Two Position Spring Return Actuators:
The MB6 is a two position, spring return actuator. It is designed not to falsely spring return in the event of brief power cuts or a
low voltage drop below 18V DC. A solenoid disengages the spring return mechanism from the the gear train; After 2 seconds
power loss the SR mechanism will activate; subsequently, there is a 3 second delay after power returning before the actuator
will accept the control signal.

Inlet Pressure to Valve (kPa)
Pressure Drop Selection
Modulating control valves are usually selected to take a pressure drop of at least 50% of the “available pressure.” As “available pressure” is often difficult to calculate, the normal procedure is to select a valve using a pressure drop at least equal to that in the coil or
other load being controlled (except where small booster pumps are used) with a minimum pressure drop of at least 5 psi (34 kPa).
When the design temperature drop is less than 33°K for conventional heating systems, higher pressure drops across the valve are
needed for good results (see below).

DuraDrive Ball Valves and Actuators
Flow Coefficient Selection
When sizing a valve, you must select a flow coefficient (Kv).
It is calculated using the formula:
Kv = (m3/h)/(√ ∆P ) (∆P is in bar)
Flow Characteristics
The VB210R and VB310R ball valve assemblies provide equal percentage flow, which is achieved
with a flow characterising insert. The parabolic shape of the orifice allows a gradual change in flow,
so that equal movements of the valve stem, at any point of the flow range, change the existing flow
an equal percentage, regardless of the flow rate. As shown in the graph, a ball valve equipped
with the characterised flow insert mirrors the flow characteristic of the coil, resulting in linear heat
transfer.

Using Pipe Reducers with Ball Valves
This chart provides estimated effective Kvs when using pipe reducers with ball valve assemblies. Use these estimated effective Kv’s in place of the rated Kvs when reducers or increasers are located within 6 pipe diameters upstream and 3 pipe
diameters downstream of the valve.
Caution
!
Do not reduce the valve size to less than one-half the line size, as this may weaken the pipe
reduction area. Physical injury can result if the weakened piping fails.

Water System Maintenance
Maintenance
The ball valve assembly itself requires no maintenance. The stem and packing design eliminates
the need for packing adjustment for the life of the
valve. However, regular maintenance of the total
heating and cooling system is recommended to
ensure sustained optimum performance.
Field Repair
Neither valve nor actuator are field repairable.
Replace entire unit as necessary.

All heating and cooling systems are susceptible to valve and system problems caused by
improper water treatment and system storage
procedures.The following guidelines are to help
avoid valve and water system problems resulting from improperly treated water or storage
procedures, and to obtain maximum life from
the valves. To maintain non-damaging conditions, clean the system prior to start up. Use a
nitrite or molybdate based treatment program.
Use filtration equipment where needed. Properly
store off-line systems and monitor water treatment
results using corrosion test coupons. Durability of
valve stems, balls, seats, and packing is dependent on maintaining non-damaging water conditions. Inadequate water treatment or filtration, not
in accordance with chemical supplier/ASHRAE
handbook recommendations, can result in corrosion, scale, and abrasive particle formation. Scale
and particulates can result in stem and packing
scratches, and can adversely affect packing life
and other parts of the hydronic system. Follow the
advice of a water treatment professional.

DuraDrive Ball Valves and Actuators
Mounting
The valves can be mounted in horizontal or vertical piping. When installed in horizontal piping, the actuator must be above
the valve body. When installed in horizontal piping the actuator can be tilted left or right but it must not be tilted below 90°
from vertical.
