Explosion-Proof Valve Actuator

About Explosion-Proof Valve Actuator
Our explosion proof electric actuators are designed to be used in hazardous areas where flammable or explosive gases, vapors, mists or dust are present. They are rated for Class I, Div 1 conditions with flameproof enclosures and conduit seals that prevent sparks and heat from entering the power shaft. These actuators are ideal for oil/gas, chemical/pharma, and any other facility handling combustible materials.

We offer several models ranging in output torque from 350in/lbs to 725in/lbs with modulating and heating accessories available. Each model is built to order for your specific application, please contact us to learn more.

Pneumatic Explosion Proof Valve Actuator
Pneumatic explosion proof valve actuators are driven by compressed air to move the blades of multileaf dampers into OPEN or CLOSED positions. The pneumatic actuator itself is not considered explosion proof but the electrical accessories that control it such as the solenoid valve or the electric valve positioner have to meet stringent requirements to make sure the circuit cannot generate an open flame or excessive heat.

UL, ATEX and IECEx approved, our pneumatic explosion proof valve actuators are the straight shooters of the electrical actuator world. They convert electrical energy into linear motion to control the operation of rotary or globe valves. This includes the quarter turn rotary ‘Max’ actuators for ball and butterfly valves, linear ‘Run’ actuators for 3-way and globe valves, as well as the sensor products that transmit or switch for differential pressure, temperature and more. All Schischek ‘Run’ actuators can be supplied with an optional spring return fail-safe. Explosion-Proof Valve Actuator
