Product Description
Pressure sustaining valves are regulators which control the pressure on the inlet side. They are used wherever a specific inlet pressure must not be exceeded, for example limiting the pressure in the inlet supply network or in transition links between supply networks and high demand large users. Their compact construction makes them ideally suited for applications where space is limited, for example in ducts. They can be used for commercial or industrial applications within the scope of their specification.
