    Performance advantages of stainless steel pneumatic ball valve:
      1. The stainless steel ball valve is made of silica sol precision casting and is connected to a pneumatic actuator. It can not only serve as a switch and cutoff, but also as a flow regulator.
    2. Diversified selection. By choosing different valve body and valve seat materials, it can be applied to different working conditions and media.

    3. It has a wide range of applications and can be used in normal temperature and pressure situations, as well as in high temperature, high pressure and low temperature conditions.

    4. Pneumatic stainless steel ball valves use gas as the power source, and the pressure is generally around 0.4-0.7MPa, which is relatively safe. If there is a gas leak, the gas can be discharged directly, causing no pollution to the environment and having high safety.


    Stainless Steel Pneumatic Ball Valve Accessory Options:

    Echo device: also called limit switch, remote feedback switch signal (can be explosion-proof)

    Solenoid valve: choose two-position five-way for double-acting, choose two-position three-way for single-acting (can be explosion-proof)

    Triple piece: can stabilize the air source, filter, and add lubricating oil to the cylinder

    Cut-off accessories: single solenoid valve, double solenoid valve, limit switch transmitter.

    Adjustable accessories: electrical positioner, pneumatic positioner, electrical converter.

    Air source treatment accessories: air filter pressure reducing valve, air source treatment triple piece.

    Manual mechanism: turn the hand wheel mechanism to manually switch the valve
