The VC6936 Fail Safe Floating Control Valve provides proportional control of hot or chilled water in commercial heating and cooling applications, such as unit ventilators. On a power failure, this patented actuator design drives the valve to the fail safe position, either fully open or closed according to the installerТs wiring connections. The VC6936 uses a microprocessor-controlled, low voltage stepper motor with a supercapacitor-based power supply capable of storing enough power to drive the valve to its fail safe position when 24V power is removed from the actuator. The VC hydronic valve consists of a valve body and replaceable characterized cartridge assembly. When used with a Honeywell VC6900 or VC7900-series actuator, the valve provides proportional flow control. Three-way bodies may use cam-operated cartridge travel to resist water hammer. Limit switches prevent motor overrun.
