    Pneumatic globe valve (DN100mm) with flange connection, equipped with pneumatic thin-film actuator, DC24V solenoid valve, limit switch and air filtering pressure reducing valve. Nominal pressure is PN16, providing reliable fluid control. This 3 1/3inch pneumatic disconnecting valve has the advantages of simple structure, rapid opening and closing without leakage, easy maintenance, waterproof, explosion-proof and so on.


    • Top-guided construction with multi-spring membrane actuator.
    • Compact structure, light weight, sensitive action, fluid channel is S streamline, small pressure drop loss, large capacity, easy disassembly and installation.
    • By using a thin-film multi-spring actuator connected to the adjusting mechanism by three columns, the overall height can be reduced by about 30 per cent and the weight by about 30 per cent. The overall height can be reduced by about 30 per cent and the weight by about 30 per cent.
    • The valve body is designed according to the principle of fluid dynamics into an equal cross-section low flow resistance flow path, the rated flow coefficient increases by 30%.

    Tips: What is Pneumatic Globe Valve?

    A pneumatic globe valve is a device that controls the opening and closing of a valve body by means of a pneumatic actuator. The valve design consists of a spherical or cylindrical spool that is pushed by a pneumatic actuator to cut off or regulate the fluid.

    Pneumatic shut-off valves are widely used in industrial automation systems, especially in liquid or gas pipelines, to achieve precise control of fluids.

    The operating principle of this type of valve is to drive the actuator by air or gas, so that it pushes the spool up and down, thus changing the size of the valve's passage to realize the regulation or closure of the fluid.

    Pneumatic globe valves are usually characterized by fast response, remotely controllable and high-precision adjustment, and are suitable for industrial scenarios that require frequent flow adjustments or remote operation. It is widely used in chemical, petroleum, electric power and other industries, providing a reliable means of control for fluid piping systems.
