Highlight: Stainless steel internal and external thread safety valve
Product introduction:
Safety valve is a kind of automatic pressure relief device for pressure equipment, container cargo line. When the pressure in the protected system increases beyond the allowable value, the valve automatically opens, discharge part of the excess medium, to prevent the system pressure continues to rise, when the system pressure decreases to a specified value, the valve can automatically close, so as to ensure the normal operation of the system.
