    Dump Valves
    DVU Series
    The DVU Series features pneumatically controlled
    dump valves. The valves open and close automatically
    by pneumatic control from a FW Murphy level controller
    and dump valve operator. Diaphragm actuated, the DVU
    series dump valves operate at 30–70 psi (207–483 kPa)
    [2.07–4.83 bar] and up to 2000 psi (13.8 MPa) [138 bar]
    vessel pressure (depending on the model).
    A key benefit of this design is a hex union that provides
    the ability to replace the seat without removing the valve
    from piping.
    The DVU Series is compatible with FW Murphy level
    controllers. They feature a soft seat valve and manual
    valve operator.
    Dimensions
    Designed for gas compressor scrubbers, the DVU
    Series can be used to dump any liquids compatible with
    its materials of construction.
