Explosion Proof Electric Actuator 3 Way Ball Valve is a kind of electrically-actuated valve which is suitable for the occasions that require the flammable liquid, gas or powder to be diversion or switching the flow direction. It is mainly used in petroleum, chemical, water treatment, shipping, paper making, power plant etc.
It is driven by 380V/220V AC power supply, or it can be powered by 24V DC and inputs 4-20mA current signal or 0-10V DC voltage signal for proportional control. It is an explosion-proof electric actuator with manual function, visual valve position indication, simple connection and easy operation.
The Series WE31 electric actuator is a full port 3-way 316 SS ball valve with an ISO 5211 direct mounting pad to simplify automation and a blowout proof stem. It is designed with a PTFE seat and seals to provide low fluid resistance for high flow rates. Its compact design makes it ideal for smaller size ball valves (2″ and below), dampers and similar quarter-turn devices.
Schischek offers a wide range of explosion proof electric actuators including WE (weather-proof) and XE (explosion-proof) models for use with ball, butterfly, plug valves and other quarter-turn applications. ATEX and IECEx certified, they can be supplied with either two-position or modulating control. All actuators are engineered and manufactured to the highest safety standards in accordance with ATEX94/9/EC and come complete with thermal overload protection and permanently lubricated gear train. Torque ratings range from 5Nm to 150Nm.Explosion Proof Electric Actuators On/Off
