DBT / DBWT PRESSURE REMOTE RELIEF VALVE

DBD PRESSURE RELIEF VALVE

DB10 PILOT OPERATED PR RELIEF VALVE

DBW10 PILOT OPERATED PR RELIEF VALVE

Pressure relief valve types ZDB and Z2DB are pilot sandwich type pressure controls. ZDB versions offer single port pressure control, while Z2DB models offer dual port pressure control. Z2DB models can be configured as either port relief or cross port relief. The ZDB program offers multiple spring options.

Features

  – A+B → T; A → B and B → A

• Adjustment type:
  – Rotary knob with scale

Directional valves type WEH are solenoid operated directional spool valves. They control the start, stop, and direction of a flow. These pilot operated directional valves consist of a pilot control valve and main stage with spring or hydraulic centering options. Additionally, the pilot and drain configuration may be selected. A full array of spools are possible with variations in voltage and electrical connection, all within the program. Flow and pressure rates from 4000 PSI to 5000 PSI and 42 GPM to 120 GPM cover a wide range of applications.
