Essence: A valve that achieves one-way opening and closing by rolling a rolling ball along a slide, using the self weight of the ball or the pressure of the medium to block backflow.
Core features:
Rolling ball+slide structure: The ball freely rolls inside the guide rail, pushing it open when flowing forward, and quickly resetting and sealing when flowing backward;
Low flow resistance design: Full bore flow channel, suitable for high flow rates, particles or viscous media;
Wear resistance and high temperature resistance: Metal spheres (such as stainless steel) are suitable for high temperature or corrosive working conditions, with a long service life.
Typical applications: Pipeline systems that require wear resistance and backflow prevention in industries such as petroleum, chemical, and slurry transportation.
