摘要： A proportional pressure release valve comprising a valve body incorporating a valve seat, a valve closure member mounted in the valve body and cooperable with the valve seat to control flow of fluid through the valve from an inlet pressure port to an outlet tank port, and electromagnetic control means having a push pin operable to move, via resilient means, the valve closure member in dependence upon the magnitude of a control current applied thereto, wherein the valve further comprises damper means provided between the push pin and the valve closure member. The valve may also comprise an anti-cavitation ring having a bore and disposed downstream of the valve seat, the anti-cavitation ring being apertured to provide a fluid connection between the ring core and the tank port. The valve closure member may be guided for movement towards and away from the valve seat by guide means comprising at least one linear bearing.
