    Series Self-acting Valves

    Y1, 2, 3 Series self-acting valves


    Y1, Y2, Y3 series self-operated valve are control devices draw their energy from the process medium which creates sufficient force to move the final element. Y1 series are single seat construction, Y2 series are two seats and Y3 are caged type.

    Bellow sealed bonnets are available for theses series.

    Y5 Micro-pressure self-acting single seated globe valves


    Y5 series features No packing stuff, high sensitivity;

    Typical applications: industrial combustion furnace system fluid, such as gas, air flow ratio, to achieve the desired effect of the combustion; for the hydrogen cooling generator sealing oil system, control sealing oil and hydrogen pressure difference, to ensure reliable sealing.
