Non-rising Stem Resilient Seated Gate valve

The Non-Rising Stem Resilient-Seated Gate Valve consists of a valve body, bonnet, stem, stem nut, gate, and other components. This valve achieves an excellent sealing effect by utilizing the compensatory action of a resilient gate, which undergoes slight elastic deformation. It boasts significant advantages such as effortless operation, reliable tight sealing, superior elastic memory, and a long service life. The valve features a full-bore design, non-rising stem operation, flanged connections, and a flat-bottomed seat profile that prevents the accumulation of debris.
