Modulating actuator for VC Series valves
VC7900 Series Specification sheet (English) 下載
Overview
Control central heating and cooling, fan coil systems, radiators and convectors. Depending on the model, it can be controlled by a low voltage SPST or SPDT switch, pulse-width modulated 24 Vac signal, or floating input, modulating controller.
Features
•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.
