• Same as the PDBASH with D03 rotated 90 degrees to match industry standard
• Removeable orifice plug options
• Ships standard with an orifice installed in the ‘P’ port & according to Plug option #1
Dump Valve or ON/OFF valve
Can be used as a dump valve by Connecting ‘X’ to the ‘B’ port (side of insert) & connecting ‘Y’ to drain. The diagrams to the right show the two different plug options. Plug option #1 will allow the valve to dump in the de-energized state & Plug option #2 will allow the valve to dump in the energized state.
Note: If port ‘A’ is connected to a working port, then connecting ‘X’ to the ‘B’ port as shown above does not prevent pressure at A from overcoming the forces acting to keep the valve closed. Flow could occur from A to B. To prevent this use a separate pilot pressure for X.
Only one orifice installed in ‘P’ port of D03 interface. Other orifices are optional.
