PTFE Lined Ball Check Valves
Salient Features
• 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 – EN – 588–1
• Lining Standard as per ASTM F 1545
• ”ALLINES” make fully lined ball check valves are ideally designed for the back flow control of all fluids and gaseous media.
• Two – Piece body designed check valve provides high stability, rigidity and eliminates potential leak path and can be installed either vertically and dependent up on application horizontally as well.
• 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.
• Inside body with full lining guide for ball, guided ball for better sealing in horizontal position.
• The valves are normally equipped with solid PTFE Balls for specific application
• 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.
Optional Features
• “O” Ring design available for Gas application for tight shut off.
• Large sizes on request
