Product Description

Butt welded triple offset butterfly valve are good sealing performance,so it improve the reliability of the system. It has the advantage that:1.low friction resistance 2. Open and close are adjustable, labor-saving and flexible.3. Service life is longer that soft sealing butterfly valve and can achieve repeated on and off.4. High resistance for pressure and temperature.

 

1. Reliable sealing,convenient operation,opening and closing fast.

2. This kind of valve with no flange, which makes pipe elegantly and binding up conveniently.

3. It adopt triple offset elasticity or multiple layers hard sealing configuration, the hermetical capability can reach to reliable sealing performance.

4. The sealing of disc can be replaced by loosening the disc ring bolts, saving the cost of the valve.

5.The ends of valve inlet port and outlet port has the annular boss, which is conducive to the valve and pipe welding heat absorption and diffusion.

Butterfly valves are quarter-turn valves that are best used for the stop/start of media flow in pipelines. When the valve handle is turned 90°, it either opens or closes completely. Throttling can be a bit tough, but these valves can still be used for regulating purposes.

Butterfly valves are usually installed in a fully open position. This is because installing the valve in its closed position can cause difficulties with the seat and seal positions.
