Selection Guide

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 below. Two-Way valve ﬂow should go A to AB. Threeway 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.

Installation Notes

• Verify 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.

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.

ns may cause equipment

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 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.

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 ﬂoating 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.

In order prevent a false spring return, a solenoid is used to disengage the gear for spring return. When power is removed for more than two seconds, spring return valve assemblies return to their normal position. Non-spring return valve assemblies remain at their last position when power is removed. The spring return feature should not be used for routine, normal operation.

Spring Return and Non-Spring Return actuators with time-out 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 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.

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.
