Function, section for DAW Series Pressure Cut-off Valve
Pilot Control Valve:
- The pressure cut-off valve includes a pilot control valve (2), which is integral to the pressure regulation mechanism.
- This valve manages the hydraulic fluid flow based on the set pressure values, ensuring the main spool operates effectively.
Main Spool Insert:
- The valve optionally includes a main spool insert (4), which directly influences the hydraulic flow paths.
- The main spool opens and closes the connection between ports P and T, or P and A, based on the hydraulic pressure and pilot control signals.
Circuit Configuration Notes:
- For circuit setup with Type DAC, connections for actuator (A), pump (P), tank (T), control lines (8) and (10), and check valve (7) must be designed according to size and flow requirements.
- Ensure connections have sufficient cross-section and are arranged to avoid blockages. A well-dimensioned check valve between the actuator and pump is necessary, with flow characteristics matching or exceeding those in the characteristic curves on page 12.
Pressure Relief and Switching:
- The valve allows diverting pump flow between ‘P to T’ and ‘P to A’ based on pressure changes.
- A switching pressure differential (either 10% or 17%) relative to the set cut-off pressure triggers the main spool’s movement, facilitating this diversion.
Adjustment Capabilities:
- The “FS” version allows freely adjustable switching pressure differentials.
- The effective force at the pilot spool can be adjusted to be 10% or 17% higher than at the ball, ensuring precise control over pressure relief and switching functions.
