CARTRIDGE VALVE FOR USE WITH VC SERIES

The VC hydronic valve consists of a valve body and

replaceable characterized cartridge assembly.

Depending on the valve model selected, they can be

used with a VC2114 or VC8114 series actuator to provide

on-off flow control, or with a VC6930 or VC7930 series

actuator to provide proportional flow control. Two way

bodies may be plumbed in either direction. Three-way

bodies may be used in either diverting or mixing

applications.

Replacing the cartridge rebuilds the valve. The valve

body should be able to stay in the pipes indefinitely.

VC actuators, ordered separately, use cam-operated

cartridge travel to resist water hammer. Limit switches

prevent motor overrun.

VCZA,B,M,N SERIES INSTALLATION PLUMBING When Installing This Product... The valve may be plumbed in any angle, including vertical piping, but preferably not with the actuator below horizontal level of the body. Make sure there is enough room around the actuator for servicing or replacement. 1. 2. 3. 4. 5. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

VCZA,B,M,N SERIES 1. 2. 3. 4. 5. Disconnect power supply before servicing to avoid electrical shock or equipment damage. Depending on the installation, it may be necessary to disconnect leadwires to valve actuator, or depress tab on Molex™ connector and remove. Where appropriate, label wires for rewiring. Remove valve actuator by pressing up on the latch mechanism located directly below the red manual open lever with thumb (See Figure 5).
