Safety Warning

Full Product Description

The Parker Bestobell cryogenic pressure build up valve maintains a system pressure on a cryogenic storage tank on a process line, therefore optimising safety. As the pressure falls, the valve opens and allows liquid to pass into the vaporiser. The gas generated is returned to the vapour space at the top of the vessel.  
It has high flow characteristics, enabling it to fill or empty the tank quickly. A PTFE seal ensures tight shut off to enhance safety.  
The pressure build up valve operates on both liquids and gases.
