    摘要: A fluid regulating device includes a regulator valve, an actuator and a pilot regulator valve assembly. The pilot regulator valve assembly provides a pressure load to a surface of a diaphragm of the actuator in response to changes in downstream pressure being applied to the opposite surface of the diaphragm. An upper cavity of the pilot regulator valve assembly is in fluid communication with a control cavity of the actuator, allowing both the actuator diaphragm and the pilot regulator valve assembly diaphragm to simultaneously sense pressure variations within the cavities. As the downstream pressure varies, the diaphragms of both the actuator and the pilot regulator valve assembly displace to regulate the downstream pressure and the pilot regulator valve assembly maintains a load pressure. The regulator further includes a balanced regulator valve applying a balancing force to offset a force of upstream pressure on a balanced valve plug.

    摘要: A system for hydraulically managing fluid pressure between selected set points includes a pilot control system operably coupled to a main valve. The pilot control system includes at least one fluid conduit, a variable orifice assembly, and a control pilot valve apparatus. Fluid is passed through a fixed orifice and into a first chamber of the control pilot valve apparatus. Fluid is passed through the variable orifice of the variable orifice assembly and into a second chamber of the control pilot valve apparatus. The main valve is hydraulically opened or closed in response to a pressure differential between the first and second chambers of the control pilot valve apparatus so as to manage fluid pressure downstream of the main valve between the selected upper and lower set points.

    摘要: A pilot valve (2) for controlling operation of a hydraulically-actuated pressure reducing valve, the pilot valve including a housing (4), and a first valve member (15) mounted in the housing for longitudinal movement along an axis relative to the housing and to a second valve member (22) in response to the outlet pressure of the pressure reducing valve. The first valve member is provided with an aperture (20) and the second valve member comprises a closure portion which varies the effective flow cross section of the aperture in accordance with relative longitudinal movement between the first and second valve members. An adjuster (26) controls the relative rotational position of the first and second valve members, the closure portion having a profile such that relative rotation between the first and second valve members causes the closure portion to vary the effective flow cross section of the aperture (20).
