Worcester Controls A34 Series 34 Pneumatic Actuator

The Worcester Controls A34 Series 34 Pneumatic Actuator provides approximately 160 in-lb of output torque at 80 PSI, delivering dependable 90-degree quarter-turn actuation for ball valves in industrial process control systems. Available in pneumatic double-acting or spring-return configurations, it operates from 60–125 PSI (80–125 PSI for spring-return models) and uses a modified Scotch Yoke design to achieve precise 90° rotation. With a 1/4 in NPT air connection and 1/2 in NPT conduit, this heavy-duty actuator is built for clean, lubricated compressed air in environments from 0°F to 160°F and compatible with pneumatic valve control assemblies and quarter-turn valves. It is commonly used in chemical processing plants, water treatment facilities, steam systems, compressed air lines, food processing equipment, and broader manufacturing automation applications to automate valve actuation, support retrofit projects, and upgrade flow control in automation systems.
