Honeywell VC7936BB1800 1/2 1.9Cv Module Failsafe Act

The VC7936 Fail Safe Modulating 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 installer’s wiring connections. The VC7936 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. DIP switches are used to select actuator response time, flow characterization, motor timing, and control signal.
