The DHD6806/02 is one of the largest Inward Pressure Relief Valves we offer and are supplied in a range of settings.
Valves can also be mounted in reverse positions to act as Outward Relief Valves.
These valves are commonly used along with our range of Tank Vent Dryers to give added protection in case of blockages. The BSP thread mean they can be easy mounted into standard pipe fittings.
