Precision Control Starts with the Right Actuator
SPC actuator packages are engineered to match your valve, service conditions, and control requirements, so you get stable modulation, dependable shutoff, and repeatable performance, cycle after cycle. Offering compact rack & pinion, linear & rotary spring diaphragm, high cycle double acting piston, and rotary electric actuation, we help you select and configure actuation that fits the job, not just the bolt pattern.
Built for Real-World Process Control
When actuation is undersized, misapplied, or poorly integrated, even a great valve becomes a problem. SPC approaches actuation as a complete control solution: design + engineering + sizing + valve + actuator + accessories + testing, backed by fast response and an industry-leading 2-year warranty.
SPC’s AR RD/RS platform supports dependable quarter-turn automation for demanding process applications. Configured for control or on-off service, AR1 packages are designed to integrate cleanly with common accessories and feedback options.
Rotary Double Acting Piston actuators for higher torque needs, frequent cycling, and consistent response.
Rotary Spring Diaphragm actuators for dependable spring return operation and stable control performance.
Linear Double Acting Piston actuators for higher thrust requirements and aggressive cycling.
Linear Spring Diaphragm actuators for reliable spring return action and precise modulation in control applications.
Rotary Electric (ON-OFF / Modulating / Spring-Return) for quarter-turn service when instrument air is not available or electric actuation is preferred.
Whether you need a replacement valve, a custom severe service trim, or help troubleshooting a tough application, our team is ready to help.
