Butt Weld Butterfly Valve-Butterfly valve series-蝶阀厂家-上海冠环阀门制造有限公司

Product Structure Features

Butt-welded bi-directional sealing butterfly valve has one more offset feature compared to double offset design, which is the seat cone axis offset from the stem centerline that reduces the operating torque. Triple offset butterfly valves are widely used in power plant, petrochemical, metallurgy, water supply and drainage system, municipal construction as throttling flow and shutoff equipments.

Its main structural features are

1. The butterfly plate and the sealing surface open and close without friction, and are forced to seal;
2. Can be installed in any position;
3. Zero leakage structure design;
4. Metal and non-metal, metal and metal sealing methods can be selected;
5. There are one-way valves and two-way valves for customers to choose;
6. Dynamic load type packing can be selected;
7. Low leakage filler can be selected to meet the requirements of ISO 15848;
8. The valve stem can be extended;
9. Cryogenic valves or ultra-cryogenic valves can be designed according to customer requirements.
