    • A pressure regulating valve includes a body having an outer surface, the interior of the body defining an inlet chamber adapted to receive a fluid at a process pressure, and an outlet chamber. The body includes at least one inlet passage communicating with the inlet chamber and the outer surface, and at least one outlet passage communicating with the outer surface and the outlet chamber. A reference housing is adapted to be disposed in fluid communication with a fluid at a predetermined reference pressure. An annular membrane is disposed between the body and the reference housing, so as to circumscribe the inlet and outlet passages. The membrane is arranged such that, when the reference pressure is higher than the process pressure the membrane engages at least one outlet passage, and when the process pressure is higher than the reference pressure, the membrane is not engaged with the outlet passage.
    • 压力调节阀包括具有外表面的主体,主体的内部限定适于在过程压力下接收流体的入口室和出口室。 主体包括与入口室和外表面连通的至少一个入口通道,以及与外表面和出口室连通的至少一个出口通道。 参考壳体适于被布置成与预定参考压力的流体流体连通。 环状膜设置在主体和参考壳体之间,以便包围入口和出口通道。 膜被布置成使得当参考压力高于处理压力时,膜接合至少一个出口通道,并且当过程压力高于参考压力时,膜不与出口通道接合。
