Piping
NOTICE
RISK OF EQUIPMENT DAMAGE
Do not install in open systems using substantial make-up water.
• Follow proper water treatment practices and system procedures.
Failure to follow these instructio damage.
These valves must be piped according to the water flow diagram. Two-Way valve flow should go A to AB. Three-way
valves should be applied only as mixing valves (see diagram).
Best Practice Guidelines
It is recommended to fit a strainer upstream of the valve to increase reliability and to follow water treatment guidelines as detailed in VDI 2035.
Recommendations
The pipework system should be flushed prior to the operation.
Mounting
The valves can be mounted in horizontal or vertical piping. When installed in horizontal piping, the actuator must be above the valve body. It can be tilted left or right but it must not be tilted below 90° from vertical.
Installation Notes
• Confirm there is no overhead water source that may drip onto valve actuator.
• In normal service, some condensation may occur on or around the valve. A drip pan may be necessary or the valve body may be insulated.
• Do not cover the actuator or obstruct the manual operator lever.
• Reference product label and Product Datasheet F-27895 for additional product specifications.
It is the responsibility of the installer or product specifier to verify media compatibility of the valves construction materials with the supplier of water treatment/heat transfer solution.
Installing the Valve Body
Apply PTFE tape to the male pipe thread. Hand screw the pipe into the valve, turning it as far as it will go. Use a wrench to fully tighten the valve to the pipe. Do not over tighten or strip the
threads.
Installing the Actuator on the Valve Body
1. Turn the valve stem so the slot on top of the stem is
pointing towards the large keyed post.
2. Do one of the following:
• For a spring return actuator, press the red lever down and rotate the manual operating lever to align the stem hole with the valve stem. Then slide the red lever up to lock the manual lever in place.
• For a non-spring actuator, press and hold the red release button on the top of the actuator and rotate the

manual operating lever to align the stem hole with the valve stem, then release the red button.
3. Align the valve body with the actuator so the stem lines up with the large stem hole and the large keyed post lines up with the post hole on the bottom of the actuator.
4. Firmly press the valve and actuator together to lock into place.
The first time the valve is operated electrically, the manual operating lever of the actuator will move to the automatic position. The manual operating lever can be used to allow flushing of the system after installation.
Removing the Actuator
NOTICE
RISK OF EQUIPMENT DAMAGE
Do not use the valve body to manually open the actuator.
Failure to follow this instruction will result in damage to the actuator
NOTE: Make sure the valve stem rotates freely before and after installing the actuator. If the stem does not operate freely it may indicate that the stem was damaged and may require that the valve be replaced.
1. Press and hold the valve release lever inward, towards the valve.
2. Lift the actuator from the valve.
3. After the piping is under pressure, check the valve body and the connections for leaks.
4. After the valve and actuator are installed, power the actuator and check the operation by varying the control signal. On spring return models, the valve should return to its normal position when power is removed.
Theory of Operation
This series of proportional valve actuator assemblies is designed to make incremental adjustments to flow based on the control signal input. This actuator is not intended for continuous use in zero dead band control systems.
When power is removed for more than two seconds, spring return valve assemblies return to their normal position. Non­spring return valve assemblies remain at their last position when power is removed. The spring return feature should not be used for routine, normal operation.
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 145 seconds (approximately 2 ½ min.). Once this cycle is complete, the actuator will then accept and respond to the control signal.
NOTE: Do not use the manual operator while power is applied to the actuator. If the actuator is manually positioned while power is applied, the calibration cycle must be completed again for the actuator to function properly. To recalibrate the actuator, cycle power off for more than 6 seconds.
