Application Overview Pneumatic Actuator Selection See Table 7, Table 9, Table 11, and Table 16. IMPORTANT: The VG7000 Series Bronze Control Valves are intended to control saturated steam, hot water, and chilled water flow under normal equipment operating conditions. Where failure or malfunction of the VG7000 Series Valve could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system.
MP8000 Series Pneumatic Actuators Electric Actuator Selection The higher force MP82 (25 sq in. effective diaphragm area) and MP84 (50 sq in. effective diaphragm area) Pneumatic Actuators are used where higher maximum closeoff pressures are required, such as 1-1/2 and 2 in. brass trim valves and 1/2 through 2 in. stainless steel trim valves. Factory-mounted electric actuators are available on two-way PDTC and three-way mixing valve configurations only. Actuators can be easily field reversed if required.
VA-8x2x Series Electric Actuators The VA-8x2x Series Actuators are synchronous motor-driven, force sensor limited, non-spring return actuators that feature a 22 lb seating force in a compact design. The VA-8020 accepts floating control from a three-wire, 24 VAC control signal. The VA-8122 typically accepts proportional control from a 0 to 10 VDC control signal; however, it can be field adjusted to accept signals up to 20 VDC.

Operation VA-8x2x Series Electric Valve Actuators V-3000, V-3801-8001, and MP8000 Series Pneumatic Actuators The VA-8x2x Series Actuators operate on 24 VAC, and are available for on/off, floating, or proportional control. The signal drives the actuator motor, causing the valve stem to move in the desired direction. Once the valve stem reaches the end of travel, a shutoff force builds up. When the force reaches its maximum, a lever within the actuator trips a force sensor, which stops the motor.
VA-4233 Series Electric Actuators The VA-4233 Series Electric Actuators operate on 24 VAC or VDC power, and are available for use with on/off, floating, or proportional controllers. These actuators incorporate a stepper motor to accurately position the valve. In the event of a power failure, a spring in the actuator automatically returns the valve to the full stem-up position. All models feature a hand crank for manual positioning of the valve, independent of a power supply.
