Porvair Filtration Group manufacture a range of valves that can be incorporated into filter assemblies and manifolds including anti drain valves that prevent the loss of system fluid during filter element change.

We can include features that would prevent fluid flow if ever an element were not fitted in the assembly.

• By-pass valves that can include electrical indication that by-pass has occurred.
• Pressure relief valves to protect systems from over-pressure conditions.
• Water drain valves to remove water from fuel systems.
• Check valves to control pressure and prevent reverse flow.
