Electro-Hydraulic Scotch Yoke Actuator

It is powered by a motor which converts electrical energy into mechanical torque.

  • Suitability for SIL 2 & SIL3 environments

  • Partial Stroke Test (PST) device

  • Self contained, only requires electrical power

Pneumatic Rack & Pinion Actuator

Rack and Pinion actuators are for automation and operation of quarter-turn valves. 

The actuators are available in two constructions: Spring Return and Double Acting. Mechanical Spring Return is for fail-safe applications and can be assembled for “Fail-Close” or “Fail-Open” safety function.

Double Acting actuators can be used for a “Fail-In-Last-Position” safety function.

  • Special teeth profile double rack and pinion construction

  • Maximum working pressure 8 bar, Special version for 13 bar available

  • Temperature rang NBR -20 °C to +80 °C, VITON -20 °C to +125 °C,

  • Flourosilicon -60 °C to +110 °C

  • Robust anodized aluminum bodies ensure even expansion under thermal influences, no jumping of the piston and a high level of corrosion protection.

  • Compliance with international interface standards ISO 5211/DIN 3337 and VDE/VDI 3845 (NAMUR).

  • Simple retrofitting of accessories, such as solenoid valves, limit switch, positioners, etc.

  • Piston guide bearing with wide contact surface, increased efficiency and cycle life.

  • Independent open and closed adjustment (standard across S050-S200) is indispensable where finite adjustment or limited rotation is required.

  • Valve and accessory connections according to the latest international standards.

  • Stainless steel pinion.

  • Body with dual ISO 5211 mounting connections.

  • MaxGuardTM – Special coating for corrosive and aggressive applications.
