The Johnson Controls VA-7152-1001 Actuator is a synchronous, motordriven actuator which provides proportional control of valves with up to 3/4 in. stroke in HVAC Applications. This compact, non-spring direct mount return actuator has a 90 lb (400 N) force minimum, and responds to a variety of input signals and can be easily field mounted or ordered factory coupled to VG7000 Series Bronze Control Valves. In addition, the VA-7152-1001 can be field-mounted to VB-3766, 3966, and 4332 bronze flare valve bodies.
Features
The Johnson Controls VA-7152-1001 includes a magnetic clutch, which provides constant output force for positive closeoff of valves, and protects the motor in stall conditions. Selectable direct and reverse action simplifies setup and installation while durable construction provides a longer cycle life. This compact unit provides 90 lb force output, covering a wide range of applications with just one actuator. The Johnson Controls VA-7152-1001's unique yoke design enables easy field mounting to valves, reducing installation and stroke adjustment time. Applications include uses in conjunction with VG7000 Series Valves for hot water and chilled water systems. For factory mounted options, refer to Electric Valve and Actuator Selection Charts. For VG7000 Series Valve options, refer to VG7000 Series Bronze Valves, 1/2 Through 2 in. (15 to 51 mm), Two- Way and Three-Way with Electric Actuators.
