Overview
The Worcester Controls A34N Series 34 pneumatic actuator is a solenoid-free actuator designed for direct pneumatic control of industrial valves. The A34N model operates without integral solenoids, relying instead on remote pilot or manual air switches for operation. This design makes it ideal for applications where external control logic or manual switching is preferred. The actuator delivers consistent torque throughout the full cycle, providing fast and positive valve positioning in demanding industrial environments.
Key Features
- Solenoid-Free Design: No integral solenoids; operates via remote pilot or manual air switches for flexible system integration.
- Compact Form Factor: Space-saving design suitable for confined installation spaces without sacrificing performance.
- Tailored Torque Mechanism: Modified scotch yoke mechanism ensures smooth, consistent operation throughout the full cycle.
- Dual Configuration Options: Available in Double Acting and Spring Return variants to match specific application requirements.
- NPT Air Connections: Two 1/8″ NPT ports for straightforward pneumatic integration.
