Product Application

HL Cryogenic Equipment’s vacuum jacketed valves, vacuum jacketed pipe, vacuum jacketed hoses and phase separators are processed through a series of extremely rigorous processes for the transport 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 tanks, dewars and coldboxes etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, hospital, pharmacy, bio bank, food & beverage, automation assembly, rubber products and scientific research etc.

Vacuum Insulated Flow Regulating Valve

The Vacuum Insulated Flow Regulating Valve, namely Vacuum Jacketed Flow Regulating Valve, is widely used control the quantity, pressure and temperature of cryogenic liquid according to the requirements of terminal equipment.

Compared with the VI Pressure Regulating Valve, the VI Flow Regulating Valve and PLC system can be intelligent real-time control of cryogenic liquid. According to the liquid condition of terminal equipment, adjust the valve opening degree in real time to meet the needs of customers for more accurate control. With the PLC system for real-time control, the VI Pressure Regulating Valve needs air source as power.

In the manufacturing plant, VI Flow Regulating Valve and the VI Pipe or Hose are prefabricated into one pipeline, without on-site pipe installation and insulation treatment.

The vacuum jacket part of the VI Flow Regulating Valve may be in the form of a vacuum box or a vacuum tube depending on field conditions. However, no matter what form, it is to better achieve the function.
