    • Self-operated Post-valve Pressure Control Valve

    The self-operated (post-valve) pressure control valve consists of a control valve, an actuator, and a spring for setting pressure. It is suitable for non-corrosive liquids, gases, and vapors. It functions as post-valve pressure control in system pipelines. When the post-valve pressure rises, the control valve closes.
