摘要： A pilot operated valve has a poppet that is held against a valve seat by pressure in a control chamber on an opposite side of the poppet and by force from a feedback spring. The force feedback spring also engages a pilot valve spool which controls the flow fluid from a control chamber. When a electrically driven actuator moves the pilot valve spool and fluid is released from the control chamber, inlet pressure acting on the poppet causes the valve to open. As the poppet moves away from the valve seat, the feedback spring exerts more force on the pilot valve spool so as to meter the fluid being released from the control chamber. When the force of the feedback spring counterbalances the actuator force, an equilibrium condition occurs and the poppet stops moving at the desired flow control position.

摘要： A pressure regulating system having a tamper-proof safety feature. A pair of seats are mounted to an annular pipe. A first bleed pipe, with a fixed restriction, extends from an inlet conduit to a first chamber. The first chamber is separated from a second chamber by a second diaphragm. A second bleed pipe extends from the second chamber to an outlet pipe. A bleed off mechanism is sealed within the outlet conduit and includes a compressible bellows. When compressed, which occurs when a predetermined pressure level is attained in the outlet conduit, a third seat is moved out of sealing relation with the outlet conduit and the first chamber. This creates an imbalance of the pressures in the chambers that leads to the pair of seats being moved to seal off apertures in the inlet conduit, thereby inhibiting flow into the outlet conduit.
摘要翻译：具有防篡改安全特征的压力调节系统。一对座位安装在环形管上。具有固定限制的第一排放管从入口导管延伸到第一室。第一室通过第二隔膜与第二室隔开。第二排放管从第二室延伸到出口管。泄漏机构被密封在出口管道内并且包括可压缩波纹管。当在出口管道中达到预定压力水平时发生压缩时，第三座椅与出口导管和第一腔室脱离密封关系。这导致室中的压力的不平衡，其导致一对座被移动以密封入口导管中的孔，从而阻止流入出口导管。

摘要： A valve assembly for controlling gas delivery from a higher pressure fluid source to a lower pressure processing tool comprising a valve poppet movingly engageable with a valve seating member and a fluid permeable insert positioned between the valve poppet and the valve seating member that is unexposed to flowing fluid when the valve poppet is in a closed position thereby preventing fluid flow through the valve assembly and provides a diffusional path for transfer of all flowing fluid when the valve poppet is in an open position. The permeable insert can be inserted into the sealable and engageable surface of either the valve seat member or the valve poppet.

摘要： A valve includes a housing having a fluid inlet and a fluid outlet and defining a fluid flow path between the inlet and the outlet. A check valve positioned in the housing has a valve seat in the flow path from the inlet, a valve member movable between a seated position against the valve seat blocking fluid flow from the inlet past the valve seat and an unseated position spaced away from the valve seat, and a spring for biasing the valve member toward the seated position. A main valve assembly is removably positioned at a home position in the housing in the flow path to control the fluid flow from the check valve to the outlet. The valve assembly has a portion which engages the valve member and maintains the valve member in it's unseated position so long as the main valve assembly is at the home position, the valve member being moved to the unseated position by the spring upon removal of the main valve assembly from the housing.

摘要： A shut-off valve assembly has a main valve module and an electrically-controlled, pneumatically-actuated operator that moves the main valve module between an opened and a closed position. A number of different shut-off valve assemblies are assembled from various components or modules, such as pneumatics modules, switch assemblies, main valve modules, and solenoid valve components. The main valve modules have a variety of sizes and pipe connection styles. In some embodiments, pressurized air is supplied to the pneumatic actuator from pressurized air equipment that is situated in a facility remotely from the shut-off valve apparatus and in other embodiments, an air-delivery module is coupled to the pneumatics module to provide pressurized air to the pneumatic actuator.
