とを特徴とするカウンタバランス弁。 A counterbalance valve having a retaining spring for setting a retaining pressure and operated by internal pressure of an outlet side conduit of an actuator, comprising: a piston receiving one end of the retaining spring; and a piston moving the piston in a direction in which the retaining spring is compressed. A counter comprising a biasing piston spring, and configured such that the piston can move in a direction that expands and contracts the holding spring in response to a pressure difference between the inlet side conduit of the actuator and the piston spring. balance valve.
