Pressure Build-Up Valve DN25 & DN40
DN25 & DN40 (1” – 1½”)
To maintain the pressure in a cryogenic storage tank during liquid/gas withdrawal.
As the pressure falls the valve opens and allows liquid to pass into the vaporiser and the gas generated is returned to the vapour space at the top of the vessel.
When the pressure reaches the set pressure the valve closes and pressure building is stopped.
Maximum Working Pressure (MWP)
(Subject to End Connections)
Up to 40 bar at –196°C to +65°C
