Product Description

YH***2 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
  l. Threaded outlet of upper bodv is convenient for connection witH
  flowmeter of fueling machine.
  2. High temperature pressure relief valve is used to relieve the pressure
  with the temperature of oil in the pipeline due to the cutoff of
  close of auxiliary valve when oiling machine breaks down.
  3. (Normally open type) auxiliary valve can stop oil reverse flowing
  when it is closed.
  4. The holder can make auxiliary valve normally open to reduce the
  of oil flow and that will not affect its flux.
  5. Spring is used to strengthen sealing performance when auxiliary valve.
  6. Cutting ring is cut off under stress and ensures the cutoff moment of **0
  7. Main valve is used to close the oil flow to oiling machine from
  oil pump.
  8. Main body is made of HT**0 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.
  *0. Tumbler is a holder to keep main valve normally open. Using special alloy.Galaxy l# can ensure the normal action under *5℃.
