GELİŞİM ® check valves, used in preventing reverse flow, are the valves with the best design.
Floating type (Swing), bolted bonnet, convertible string, full transitive
Spring-loaded (lift-type) check valves
Check valve bodies have suitable connections and wall thickness for heavy working conditions. Radius connections that are wide and that have suitable radius provides a completely unobstructed flow with minimized turbulence and flow resistance during operation. In 150, 300, 650 lbs. groups, gasket seat surfaces of bonnet flanges have round female faces. 600 lbs group may be ring joint type conforming ANSI B16.20 standards, on request. In 900 lbs group valve bonnets, gasket seat surfaces conform the ANSI B16.20 standards.
