Emergency Shut-Off valve

Features and main parameters                    

1.Threaded outlet of upper body is convenient for connection with the inlet of flowmeter of fueling machine.
2.High temperature pressure relief valve is used to relieve the pressure increasing with the temperature of oil in the pipeline due to the cutoff of cutting ring and close of auxiliary valve when oiling machine breaks down.
3.(Normally open type) auxiliary valve can stop oil reverse flowing and leaking when it is closed.
4.The holder can make auxiliary valve normally open to reduce the resistance of oil  flow and that will not affect its flux.
5.Spring is used to strengthen sealing performance when auxiliary valve closes.
6.Cutting ring is cut off under stress and ensures the cutoff moment of 350-550N
