ACTUATORS

VR Series Rack & Pinion Pneumatic Actuators

VR SERIES

The VR Series pneumatic actuator features an innovative rack and pinion drive mechanism built to the latest standards, delivering high performance, reliability, and a compact design suitable for a wide range of industrial applications. Actuators come with 304 or 316 stainless steel output shafts, and FPM or silicone O-rings with special lubricant are available for extreme temperature environments, with custom designs available on request (except for the octagon output drive). Production is fully ISO9001 compliant, and every unit is pressure- and leak-tested, serial-numbered for traceability, and individually boxed. Available accessories include brackets, connectors, solenoid valves, limit switch boxes, proximity sensors, manual gear override gearboxes, positioners, and reduced-size square output shaft sleeves

VRD Series Rotary Spring Diaphragm Actuator

VRD SERIES

The VRD series offers compact, lightweight diaphragm actuators with inner and outer springs, balancing diaphragm pressure against spring force to precisely position the drive shaft for modulating and on-off service with rotary control valves. A friction-free diaphragm structure paired with a crank-slider mechanism delivers high control accuracy, while the thick-walled cold stamping case and ductile iron construction provide long service life, corrosion resistance, and protection against over-pressurization. The actuators deliver high output torque, support cold service down to -58°F (-50°C) on VRD100RA models, and feature an ISO 5211-compliant integrated output shaft for reliable installation. A manual override is available across all sizes in the event of air supply loss.

VTS Series Scotch Yoke Actuator

VTS SERIES

The VTS Series Scotch Yoke Actuator features O-ring sealing for waterproof protection and multiple protective coatings with a Teflon-lined cylinder for corrosion resistance. It operates at 3–6 bar across a wide temperature range, from a standard -4–176°F up to 302°F high-temperature and -76°F ultra-low temperature versions. Self-lubricating bearings extend service life, while the modular design allows different cylinder and spring combinations to meet varying torque needs and simplify maintenance. Internal tie rods reduce cylinder size and guide the piston to prevent eccentric wear for stable, long-lasting performance.
