Pneumatic Actuator - SP Series
The SP Series of stainless steel pneumatic actuators are the perfect solution for wash-down applications. The electro-polish finish offers excellent resistance to most corrosive chemicals and industrial atmospheres. The SP features dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life and fast operation. Available in Double Acting or Spring Return (fail-open or fail-closed).
Design Features:
- ASTM303 stainless steel with electro-polish finish
- Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle life, and fast operation.
- Stainless steel fasteners for long-term corrosion resistance
- ISO 5211 direct mounting, DIN 3337
- NAMUR standard for mounting solenoids, limit switches and other accessories
- Multiple bearings and guides on rack and pistons, low friction, high cycle life, and prevent shaft blowout.
- The two independent external travel stop adjustment bolts can adjust +5° at both open and close directions.

Pneumatic Actuator Accessories
Solenoid Pilot Valve
For efficient operation of DynaQuip pneumatic actuators, choose DynaQuip pilot solenoid valves:
- Pilot solenoid valves electrically control the air supply coming into the actuator.
- Standard NEMA 4 Housing (additional NEMA ratings available).
- The solenoid pilot valve pressurizes and exhausts the actuator piston compartments to cause the actuator to move.
- The 4-way solenoid pilot valve mounts directly to the actuator, reducing response time and saving the cost of tubing brackets and labor.
- Mounting pattern follows the NAMUR connection standard.
- Any of the following pilot solenoids will fit DynaQuip pneumatic actuators. Simply choose the correct voltage and NEMA rating (if other than 4X)
Valve Position Limit Switch
For local/ remote position indication from DynaQuip pneumatic actuators, choose DynaQuip valve position limit switches
- Provides local or remote indication of valve position
- Contains 2 SPDT switches
- NEMA 4, 4X enclosure Additional NEMA ratings and voltages are available.
- High contrast indicator for instant visual notification.
- Includes mounting bracket
- 1/2″ NPT conduit entry
