FERPI-5 INTRINSICALLY SAFE ELECTRO-PNEUMATIC CONTROL VALVE
CERTIFICATE:
FERPI-5 intrinsically safe electro-pneumatic control valves are intended for electric control of direction of compressed air flow to receiving units, such as pneumatic cylinders and motors used in machinery and equipment operating in underground workings of mining facilities:
- categorised as class “b” or “c” of methane explosion hazard,
- categorised as class A and B of coal dust explosion hazard.
FERPI-5 intrinsically safe electro-pneumatic control valves are category M1 devices, and therefore their power supply does not need to be switched off whenever explosive atmosphere occurs.
