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 and dewars etc.) in industries of air separation, gases, aviation, electronics, superconductor, chips, pharmacy, cellbank, food & beverage, automation assembly, rubber products and scientific research etc.

Vacuum Insulated Pneumatic Shut-off Valve

The Vacuum Insulated Pneumatic Shut-off Valve, namely Vacuum Jacketed Pneumatic Shut-off Valve, is one of the common series of VI Valve. Pneumatically controlled Vacuum Insulated Shut-off / Stop Valve to control the opening and closing of main and branch pipelines. It is a good choice when it is necessary to cooperate with PLC for automatic control or when the valve position is not convenient for personnel to operate.

The VI Pneumatic Shut-off Valve / Stop Valve, simply speaking, is put a vacuum jacket on the cryogenic Shut-off Valve / Stop valve and added a set of cylinder system. In the manufacturing plant, VI Pneumatic Shut-off Valve and the VI Pipe or Hose are prefabricated into one pipeline, and there is no need for installation with pipeline and insulated treatment on site.

The VI Pneumatic Shut-off Valve can be connected with PLC system, with more other equipment, to achieve more automatic control functions.

Pneumatic or electric actuators can be used to automate the operation of the VI Pneumatic shut-off Valve.
