Whether you need to actuate a valve, damper or fan in a hazardous environment, these explosion proof electric actuators are designed to reset to an open or closed position when power fails. They are also great for a variety of low power environments including solar, batteries or fuel cells.
These units are designed for use in hazardous environment applications requiring Class 1, Division 2 (explosion proof) protection. They provide a fail-safe mechanism and are certified for operation in Zone 1 or 2 environments with explosive gases and combustible dust atmospheres, as well as temperature classes from T1 to T4.
The explosion proof actuator uses a spring-return mechanism that will release energy stored in the actuator once power cuts off, opening or closing the valve depending on the application. This is the safest way to actuate a valve, especially in environments where the power will cut off frequently. This type of actuator can be used with both single- and double-acting valves.
Schischek offers a wide range of rotary and linear explosionproof products for heating, ventilation and air conditioning systems in industrial and offshore applications. Using state-of-the-art technology and PTB certified, these explosion proof electric actuators are tested according to the latest EN ISO 80079-36 and -37 norms for mechanical explosion protection, making them suitable for use in Ex areas, zones 0, 1, 2, 21, 22 – with gases, vapours, mists or dust. Use the DESIGN GUIDE PRO tool to quickly determine which explosion proof actuator system is best suited for your needs. Explosion-Proof Actuators
