1. Definition and use
Pneumatic stainless steel ball valve is a stainless steel material as the main body, driven by the pneumatic actuator valve, mainly used to cut off or connect the fluid medium in the pipeline. Its core opening and closing parts are stainless steel spheres, which can be rotated 90° to achieve fast switching control of the fluid. With the corrosion resistance and high temperature resistance of stainless steel, it is widely used in food, pharmaceutical, chemical, water treatment and other industries with high requirements for health and corrosion resistance.
2. Structure composition
Body and ball: 304, 316 and other stainless steel casting or forging, corrosion resistance, suitable for acid, alkali, salt spray and other harsh environment.
Sealing material: Valve seat commonly used PTFE (polytetrafluoroethylene), PPL (reinforced polypropylene) or metal hard seal, to adapt to different temperatures (-50ºC~250ºC) and media needs.
Valve stem: stainless steel, rust resistant and wear resistant, and the actuator connection design anti-blowout structure to ensure safety.
Pneumatic actuator: divided into single action (spring return) and double action (two-way air control), can be equipped with solenoid valve, positioner to achieve automatic control.
3. How it works
The pneumatic actuator receives the control signal (such as 4-20mA current signal or switch signal) and drives the valve stem to rotate the ball 90° :
Open state: The sphere channel is aligned with the pipeline, and the fluid is smooth.
Closed state: The ball rotates 90°, the channel is perpendicular to the pipeline, and the medium flow is completely truncated.
Adjustment function (optional) : The rotation Angle is controlled by the positioner to achieve flow adjustment (only V-open ball valve).
