  • Technical Feature

    OPERATION:

    Pressure at ① overcomes the spring-bias poppet and allows free flow to ② . Flow in the opposite direction, from ② to ① ,is blocked by the poppet.

    When the required pilot pressure is achieved at ③ ,the poppet is held closed to block flow between ① and ② .The pilot piston area to poppet seat area ratio is 3 to 1.
