    • A multiple - stage valve system (200) including a pilot fluid supply (209) and a process fluid supply (222) is provided. The multiple - stage valve system includes a first pilot valve (201) including a first port (206) in fluid communication with the pilot fluid supply and a second port (207) selectively in fluid communication with the first port. The multiple - stage valve system also comprises a second pilot valve (202). The second pilot valve can include a first port (213) in fluid communication with the process fluid supply and a second port (214) selectively in fluid communication with the first port. The second pilot valve also includes a first pressure - actuated biasing member (217) in fluid communication with the process fluid supply and a second pressure - actuated biasing member (218) in fluid communication with the second port of the first pilot valve. The multiple - stage valve system also comprises a main control valve (203). The main control valve can include a first port (220) in fluid communication with the process fluid supply and a second port (221) selectively in fluid communication with the first port. The main control valve can also include a first pressure- actuated biasing member (225) in fluid communication with the process fluid supply and a second pressure- actuated biasing (226) member in fluid communication with the second port of the second pilot valve.
    • 提供了包括先导流体供应(209)和过程流体供应(222)的多级阀系统(200)。 多级阀系统包括第一先导阀(201),其包括与先导流体源流体连通的第一端口(206)和选择性地与第一端口流体连通的第二端口(207)。 多级阀系统还包括第二先导阀(202)。 第二先导阀可以包括与过程流体供应源流体连通的第一端口(213)和选择性地与第一端口流体连通的第二端口(214)。 第二先导阀还包括与过程流体供应源流体连通的第一压力致动偏置构件(217)和与第一先导阀的第二端口流体连通的第二压力致动偏置构件(218)。 多级阀系统还包括主控制阀(203)。 主控制阀可包括与过程流体供应源流体连通的第一端口(220)和选择性地与第一端口流体连通的第二端口(221)。 主控制阀还可以包括与过程流体供应源流体连通的第一压力致动的偏置构件(225)和与第二先导阀的第二端口流体连通的第二压力致动的偏压(226)构件。

    • A valve (200) including a housing (201) and a process fluid supply port (112) formed in the housing (201) to receive a process fluid is provided. The valve (200) includes a piston (202) movable within the housing (201) between an open position and a closed position. The piston (202) includes a first pressure-compensating surface (315) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open position. The piston (202) further includes a second pressure-compensating surface (316) with a first portion (210) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open and the closed position and a second portion (208, 317) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open position.
    • 提供了一种包括壳体(201)和形成在壳体(201)中以接收工艺流体的工艺流体供给口(112)的阀门(200)。 阀(200)包括可在壳体(201)内在打开位置和关闭位置之间移动的活塞(202)。 当活塞(202)处于打开位置时,活塞(202)包括与过程流体供应口(112)流体连通的第一压力补偿表面(315)。 活塞(202)还包括第二压力补偿表面(316),当活塞(202)处于打开和关闭位置时,第一部分(210)与过程流体供应口(112)流体连通,并且 当所述活塞(202)处于打开位置时与所述过程流体供应口(112)流体连通的第二部分(208,317)。
