Unitary Valve Actuator

VC Series Proportional Actuators

Control central heating and/or cooling systems, fan coil systems, radiators and convectors. Depending on the model selected, it can be controlled by either a low or line voltage SPST or SPDT or floating controller such as a room thermostat, Aquastat control, flow switch or a 0/2 to 10 Vdc controller.

FEATURES

Use with two-way or three-way valves.

Minimal actuator power consumption.

Double insulated actuator.

Quick-connect or one meter cable electrical connections available.

Quick and easy replacement of moving parts.

Actuator head installation does not require draining the system.

Use non-fail safe proportional actuators with 3000 Series

2-way and 7000 Series 3-way VC valve bodies only.

All VC Series actuator-valve combinations provide 60 psi close-off.
