Installation

Manually Opening Valve

The manual opener can be manipulat- ed only when in the up position. The A port can be manually opened by firmly pushing the white manual lever down to the midway position and pushing the lever in. In this position, both A and B ports are open. This “manual open” position may be used for filling, venting and draining the system or opening the valve during power fail- ure.

The valve can be closed by depressing the white lever lightly and then pulling the lever outward. The valve and actu- ator will return to the automatic posi- tion when power is restored.

Note: If the valve is powered open, it cannot be manually closed, unless the actuator is removed.

Wiring

A controller and a separate transform- er is required to operate each valve. See Figures 9 and 10. Port A “open” and “closed” denote valve open and closed positions.

The typical floating controller is an SPDT controller with a center-off posi- tion. On a change in temperature from the set point, the controller will close

the normally open (NO) or normally closed (NC) contacts, driving the valve to an intermediate position until a fur- ther change at the controller.

The valve is set between the limits of the controller to satisfy various load requirements. In the event of power failure, the valve will stay in the posi- tion it was in before loss of power. When power is restored, the valve will again respond to controller demand.

Isolation Valves

Installation

The valve can be mounted in any posi- tion on a vertical line. If the valve is mounted horizontally, the actuator must be even with or above the center line. Make sure there is enough room to remove actuator cover for servicing. Mount the valve on the tube or pipe.

Note: Ensure the flow through the valve is in the direction indicated by the arrow stamped on the valve body.

Figure 11: Proper mounting for isolation valves.

Servicing/Removal of Valves

The actuator can be removed from the valve body. Removing the actuator is recommended if soldering is being conducted near the valve. To remove the actuator:

1Place the manual operating lever to the Open position, Figure 12

2Depress the locking button and lift actuator until it separates from the valve body.

Figure 12: Removing valve actuator

To install the actuator to the valve body:

3Align the slot on the shaft of the valve with the valve body notch on side of body. See Figure 13.

Figure 13: Installing isolation valve

4Install body valve into pipe.

5Wiring connections may be made either before or after actuator in- stalled on body.

6Place the manual operating lever on the actuator in the OPEN posi- tion.

7Align actuator coupling to slot on the shaft of the valve body and fit the head onto the valve body to ensure the shaft seats correctly, Figure 11.

8Press the actuator and valve body until it secures together.
