The DH/D6604 is one of the largest Stainless Steel Outward Pressure Relief Valves we offer and can be supplied in a range of settings.  Valves can also be mounted in reverse positions to act as Inward 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.
