Plastic pneumatic diaphragm valve with explosion-proof

Gas driven,cylinder material engineering plastic,size range DN15-DN50,connection way:welded、clamped&flange，pressure 5-8bar，suitable for

 inert and corrosive liquid and gaseous media。With intrinsically safe explosion-proof solenoid valve (Using low voltage, current design and limit the

 energy in the circuit, so that the circuit energy is not enough to detonate flammable materials).Comparing to usual plastic pneumatic diaphragm valve,

which have explosion-proof function,exia type is installed to 0 area,exib is to 1 area、2 area，ordinary is only for general environments.
