YH0012 Series Emergency Shut-off Valve (DOUBLE)

YH0012 Series Emergency shut-off valve is to be used together with submerged oil-pump type fueling machine. It can cut off the oil flow automatically and rapidly and is a protection for submerged oil-pump type fueling machine.This valve adopts fusible material and cutting ring. Valve core will close automatically to cut off oil-flowing pipe in case of catching fire or oiling machine damaged by knocking.

Features
1.Threaded outlet of upper body is convenient for connection with the inlet of flow meter 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·m.
7.Main valve is used to close the oil flow to oiling machine from submerged oil pump.
8.Main body is made of HT200 cast iron and inside or outside threaded inlet is for your option.
9.Testing jack is used to test the pressure in pipeline after being installed with a pressure meter.
10. Tumbler is a holder to keep main valve normally open. Using special alloy Galaxy 1# can ensure the normal action under  75 oC.
