This assembly was assembled & tested to be compatible in Class 1 Div 1 rated hazardous environments. A 3-way inline solenoid valve is nipple mounted to an MS48 explosion proof limit switch box and terminated, with SS tubing completing the air connection to the actuator ports. Containing all of the wiring within the explosion proof enclosure simplifies field installation and maximizes safety for Class 1 Div 1 applications.
