Watts Regulator PAS-400M4 Pneumatic Valve Actuator

Description:

The Watts Regulator PAS-400M4 Valve Actuator is a pneumatic rotary actuator designed to automate the operation of quarter-turn valves in industrial process control systems. Utilizing compressed air as the operating medium, the actuator delivers reliable rotary motion for opening and closing ball valves, butterfly valves, and other quarter-turn valve assemblies. Rated for operation in systems up to 125 PSI and temperatures up to 180°F, the PAS-400M4 features a rugged industrial design suitable for demanding process environments. It is commonly used in water treatment, chemical processing, manufacturing, HVAC, and fluid handling applications where remote or automated valve control is required.

Applications:

The Watts Regulator PAS-400M4 Valve Actuator is commonly used in water treatment facilities, industrial process plants, chemical processing systems, HVAC installations, manufacturing facilities, utility systems, fluid distribution networks, food and beverage processing equipment, and automated piping systems where pneumatic valve actuation, process automation, flow control, and remote operation are required to improve system efficiency and operational reliability.
