Product Features

Vortex Cleaning Closure: The beveled bottom of the gate redirects media flow during closure, creating a flushing vortex that clears valve seat deposits, ensuring 100% zero leakage with every shutoff.
Full Bore Design: The flow path matches the pipe inner diameter, eliminating turbulence and minimizing erosion.
Full Open Position: Gate retracts completely into the valve cavity, avoiding direct media impact and extending gate service life.
Fully Lined Valve Body: The one-piece molded abrasion-resistant polyurethane liner encases all internal surfaces, delivering seamless wear protection with no dead zones.
Superior Polyurethane Performance: The polyurethane used contains urethane-type repeating units with exceptional abrasion resistance—8× harder than tungsten carbide steel, 7× that of vulcanized rubber, and 3× that of UHMWPE, especially under immersion.
Self-Flushing Seat Design: A unique gate and seat configuration prevents media buildup and jamming during closure.
Gate Scraper: Integrated blade cleans the gate during operation, preventing build-up and reducing actuation torque.
Replaceable Wear Parts: The gate and liner are designed for easy on-site replacement, improving efficiency and reducing downtime.
