Total price
Monitoring a held load takes more than a tight seat valve. This pilot-operated shut off valve blocks one actuator port leak-free and adds spool position monitoring. At a cracking pressure of 7.5 bar it opens the path for up to 350 l/min, operating pressure reaches 315 bar.
Benefits
- Leak-free blocking of one actuator port at a cracking pressure of 7.5 bar
- Spool position monitoring, so the control system gets feedback on the actual position
- Subplate mounting to port pattern ISO 5781-08-10-0-16 with 2 ports
- Flow up to 350 l/min at an operating pressure of up to 315 bar
- Connector, 4-pole, M12 x 1, coding A at 24 VDC, tested by DGUV Test under certificate HM 220197-2022
- Mechanical actuation with external pilot oil return, mass 5 kg

Applications
The valve is used wherever a load has to stay put reliably and the machine control must evaluate that state, for instance on presses, lift tables and clamping systems. The spool position feedback replaces a separate sensor at the cylinder.
