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
