Application
This valve is typically used on fan coil units, baseboards or
other hydronic applications where fail safe operation or 2-wire
control is required. This valve is suitable for use in a hydronic
system with variable or constant flow.
This valve is designed to fit in compact areas where on/off
control is required using 24 VAC, 120 VAC or 230 VAC.

– A 3-way valve cannot be transformed into a 2-way valve and
visa versa.
– The flow is from A to B (see diagram below) and must be
installed so the paddle closes against the direction of flow
as indicated in the following diagrams.
– The 2-way valves can be installed on the supply or on the
return; for correct installation it is necessary to respect the
direction of flow indicated from the arrow on the body valve.

Manual Open
1. The manual opening is achieved by moving the manual
opening lever to the locked position. When power is applied,
the manual lever unlocks automatically.

Note! Rotate 180° the valve
body for NO applications

Note: An approximate 30 second delay is possible in valve movement after being
powered on. For heating applications, it is important to cycle the N/O valves
periodically during the off season or power them down to reduce the
chance of the valve sticking in the up coming heating season.
Removing the Actuator
1. Move the manual open lever to the lock open position.
2. Press the push button in and pull the actuator up.
Installing the Actuator
1. Move the manual open lever to the lock open position.
3. Align valve stem to the mating actuator hole. Move stem if
required for proper alignment.
4. Press the push button in and slide the actuator onto the
valve body, release the push button.
SAFETY INSTRUCTION
This safety alert symbol will be used in this
manual to draw attention to safety related
instructions. When used, the safety alert symbol means
ATTENTION! BECOME ALERT! YOUR SAFETY IS
INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.
CAUTION: All work must be performed by qualified personnel trained in the proper application,
installation, and maintenance of systems in
accordance with all applicable codes and ordinances.
CAUTION: Over-tightening and breakage
can occur with the use of Teflon pipe joint
compounds. Teflon provides lubricity so that
care must be exercised not to over-tighten joints. Failure
to follow these instructions could result in property
damage and /or personal injury.
WARNING: System fluids are under pressure
or temperature can be hazardous. Be sure the
pressure has been reduced to zero and the
system temperature is below 100°F (38°C). Failure to
follow these instructions could result in property damage
and/or personal injury.
