Product Features
▶ The V-shaped notch has a sharp edge, providing shearing force during the closing stroke, making it suitable for viscous media like pulp and slurry.
▶ It can also be used for throttling control. The ball and the V-shaped notch form a sectorial flow channel, allowing precise flow adjustment.
▶ The sealing surface can be treated with various hardening processes such as HCr+Stellite, Ni60/Ni55 overlays, HVOF sprayed WC (carbide) or CrC (chromium carbide), which significantly improves wear resistance.
▶ The spring-loaded seal design ensures a reliable seal with pre-tightening and compensation capabilities.
▶ The valve seat is designed with a floating structure and built-in spring, providing consistent sealing performance and preventing particle accumulation.
