control valves HB Series control Valve (with Electric Actuator). The HB control Valve with Electric Actuator is a robust user-friendly alternative to pneumatic actuators. Actuator is ideal for installations where pneumatic lines are not present. Fail-safe Mode: Super capacitors are used to drive the valve fully-closed or open in the event of power loss to the actuator. This replaces common back- ups such as springs with limited thrust or batteries with a limited life span. Fast Response Time: Fully-open or close in approximately 6 seconds making them ideal for instantaneous and semi-instantaneous water heaters. Integral Positioner: accepts 4-20 mA or 0-10 VDC control signal.
