Technical properties:

The rupture diaphragm valve is an ideal accessory of liquid injection foam extinguishing system. It has sealing functions at normal times, and once the oil tank is on fire, start the foam pump and the medium pressure in the pipe causes the diaphragm of the valve plate rupture automatically, and so as to open the doors for the foam liquid flow from the bottom to the oil tank.
