In an accumulator charging circuit the pump has to unload once the set pressure is reached and resume only when it drops. This pilot-operated pressure cut-off valve in size 20 does that for 120 l/min at up to 315 bar and works with mechanical actuation, so it needs no control voltage.

An accumulator charging circuit needs a defined point where the pump is unloaded instead of pumping against full pressure. The DA20-2-5X/200-17 pressure cut-off valve switches at the set value, works as a pilot-operated spool valve and is rated for 120 l/min at 315 bar operating pressure.
Key benefits
- Cut-off at the set value, mechanically actuated and therefore independent of the control voltage
- 120 l/min flow in size 20, matched to medium accumulator charging pumps
- 315 bar maximum operating pressure as headroom above the usual accumulator top pressure
- Subplate mounting with 3 ports and 2 switching positions, spool symbol P to A
- NBR seals for HL hydraulic fluid, weight 7.65 kg

Application
The valve is used in accumulator charging circuits of presses, clamping systems and test rigs where the pump is unloaded after charging. The gap between cut-off and cut-in pressure decides how often the pump starts per hour. It is mounted on a size 20 subplate.
