DH300 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.
