API609 BUTTERFLY VALVE TRIPLE ECCENTRIC EPDM SEAT 150LB LUG TYPE

Summary of Functions

Concentric rubber lined butterfly valve is a kind of valve with thick polymer lining on the body and disc. The lining makes the body completely isolate from medium and provides excellent anti-corrosive performance. It designs as a device to shut-off or regulate the working medium flow and installs in pipelines or vessels with medium of acid, alkali, salt and oxidant, reducing agent, organic solvent in chemical, petroleum, pharmacy, food, iron and steel smelting, paper making, water power plant etc. It can be served as gate valve, globe valves as well as other shutting off or regulating valves.

Products Features

1. Small dimensions and light weight, easy to disassembly and repair, can be installed in any position.
2. Simple and impact construction, quick open-close, small operation torque.
3. Excellent Bi-directional sealing function, Zero leakage in test.
4. Excellent medium isolation and regulating function, the flow curve tends to be straight line. Excellent regulation performance
5. Little medium is stocked in pipeline, strong anti-scouring ability , can be used for the harsh working environment

Construction Features

For this concentric butterfly valves, the center of disc sealing and the center of the shaft is coincident, for a certain amount of magnitude of interference, the sealed pressure ratio between the body seat and the disc sealing surface is created to make sure the good sealing performance of the valve.The seat of this concentric butterfly valve is elastic material such as rubber or Teflon material, and its usually used for low pressure pipeline.

The type of seat: Backrest seat, Inserted seat, the whole rubber vulcanized seat.

The connection between the disc and shaft: Taper pin connection, Two half shaft pinless shaft connection, The whole shaft pinless shaft.
