	 Technical Data
 
 Operating principle
	 Safety shut-off valve is controlled by pilot . Overpressure or underpressure release feature is when monitored downstream operating pressure exceeds set-point range, the pressure signal fed back to the pilot (pilot valve), the pilot piston moving up or moving down, so that the trolley trip, hammer down the impact of the firing pin and firing pin moves down makes disengage the hook and flap, flap valve is closed down, thereby cutting off gas to the downstream pipeline, protect downstream equipment and pipeline safety.
