Control Valves

DH300

Pressure sustaining valve

APPLICATION

Pressure sustaining valves of this type 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.
