Safety Relief Valve
Product Application
The all series of vacuum insulated equipment in HL Cryogenic Equipment Company, which passed through a series of extremely strict technical treatments, are used for transferring of liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, LEG and LNG, and these products are serviced for cryogenic equipment (e.g. cryogenic tank, dewar and coldbox etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, pharmacy, cellbank, food & beverage, automation assembly, chemical engineering, iron & steel, and scientific research etc.
Safety Relief Valve
When the pressure in the VI Piping System is too high, the Safety Relief Valve and the Safety Relief Valve Group can automatically relieve pressure to ensure the safe operation of the pipeline.
A Safety Relief Valve or Safety Relief Valve Group must be placed between two shut-off valves. Prevent cryogenic liquid vaporization and pressure boost in VI pipeline after both ends of valves are shut off at the same time, leading to damage to equipment and safety hazards.
The Safety Relief Valve Group is composed of two safety relief valves, a pressure gauge, and a shut-off valve with a manual discharge port. Compared to a single safety relief valve, it can be repaired and operated separately when the VI Piping is working.
Users can purchase the Safety Relief Valves by yourselves, and HL reserves the installation connector of the Safety Relief Valve on the VI Piping.
