    Description
    C 2.9511 Pilot-operated check valves

    Pilot-operated check valves are spring-loaded poppet valves with free flow from B to A and blocked flow in the opposite direction that can be "unblocked" by pressurizing the control port Z. The minimum pressure required for unblocking depends on the height of the counter pressure at port A (see diagram).
    In the pilot-operated version fist a smaller poppet valve located in the main valve piston is opened.

    This offers the following advantages:

    • The control pressure required for opening is considerably lower, and thereby the use of swing clamps with unfavourable surface ratios is possible.
    • pressure reduction is effected relatively softly. That saves all hydraulics components and the noise level sinks.
