VC Series Proportional Actuators

Actuator Type: Valve Fail Safe Mode: Stays in place Cable Entry: Molded strain relief, conduit clamp Dimensions, Approximate: 2.8 in. high x 3.7 in. wide x 2.7 in. deep

(70 mm high x 94 mm wide x 68 mm deep)

Electrical Protection: Double Insulated Ingress Protection Rating: IP40 Frequency: 50 Hz; 60 Hz Timing (seconds): Nominal Driving @ 60 Hz: 120 sec. Manual operation: Lever Mounting: Direct Coupled Shaft Adapter Type: Self-alignment Stroke: 0.4 in. (10 mm) Close-off: 60 psid

Control central heating and/or cooling systems, fan coil systems, radiators and convectors. Depending on the model selected, it can be controlled by a low voltage SPST or SPDT switch, pulse-width modulated 24 Vac signal, or floating input, modulating controller such as a room thermostat, Aquastat control, flow switch or a 0/2 to 10 Vdc controller.

• Use with two-way or three-way valves

• Double insulated actuator

• Five foot plenum-rated cable

• Quick and easy replacement of moving parts

• Actuator head installation does not require draining the system

• Selectable/switchable electronic fail safe normally open or normally closed

• Available with valve bodies with 1000-series 2-way and 6000-series 3-way cartridges for new construction

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