PTFE Lined Ball Check Valve

Meet design specification as per B 16.34 / Face to Face as per ANSI B 16.10 / Flange dimensions as per B 16.5
Testing Standard as per BS-EN 12266-1 / DIN-EN588 -1
Lining Standard as per ASTM F 1545
Ball Check valves have a hydraulically optimized design. The lining thickness (4.5mm) offers very high permeation resistance
The Full port design is engineered to minimize pressure drop and other improved flow characteristics
Can be installed either vertically and dependent up on application horizontally as well
Inside body with full lining guide for ball, guided ball for better sealing in horizontal position
A minimum differential pressure of 1 Bar is necessary so that the ball is pressed in to seat
Ball is properly shut off on soft seat sealing
Hollow Ball can also used for low opening differential pressure
The Valves are suitable for liquids, vapour, gas, corrosive hazardous, pure hot highly permeating media
