Series 34 Pneumatic Actuator

Increased Productivity Through Precise, Reliable On/Off Automated Control.

For dependable high cycle on/off valve operation.
Two sizes provide torques to 1000 in.-lbs.

The Worcester Series 34 Pneumatic Actuator is the most efficient actuator available, delivering "tailored torque" to provide fast, smooth and positive operation through the full cycle.

Features and Benefits

Compact, space-saving design.
"Scotch Yoke" linkage provides tailored torque.
Single external air and electrical connections on solenoid models.
Torque outputs to 1000 in. lbs (1.152 Kg. cm) @ 100 psi. air supply (7 Kg. CM²).
Minimum air consumption.
Adjustable speed control.
Built-in solenoid air pilot as standard.
Fail-safe spring return options.
Type 1, 4, or 7 solenoids.
Limit switches for general purpose, watertight, or hazardous environments.
High temperature option to 250"F (121 IC) ambient.
Baked epoxy coating resists corrosion for longer life.

Available Configurations

On double acting models, a four-way solenoid- piloted air valve built into the actuator along with two speed controls adjusts opening and closing speeds independently. On Spring return, fail safe models, a three way solenoid piloted air valve built into the actuator along with a speed control screw allows adjustment of the spring stroke cycle time.
An actuator without a solenoid for remote operation.
A spring return actuator to provide positive valve actuation in case of air pressure or electrical failure. The unit can be installed to either fail open or closed.
An actuator with limit switches. Limit switches avail- able in Type 1, General Purpose (Electrical Rating: UL and CSA listed, 15 amps, and 120, 240, 480 VAC. Temperature range -25^oF to +160^oF); Type 4, 7, 9 Hazardous Environments (Electrical Rating: UL and CSA listed, 15 amps and 120, 240, 480 VAC. Temperature range -25^oF to +160^oF); and Type 1, 3, an 4 Watertight (Electrical Rating: UL and CSA listed 15 amps, 120, 240, 480 VAC. Temperature range -25^oF to 160^oF).
