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.

Designed for gas compressor scrubbers, the DVU Series can be used to dump any liquids compatible with its materials of construction.
