Product Description

Stainless steel /Cast steel Manual butterfly valve


Effect
Flexible seal eccentric structure telescopic flange butterfly valve is another new product developed by our factory after the flange butterfly valve and expansion joint.
It is a new structure integrating flange butterfly valve and expansion joint, and is trusted by users with its good performance. This product is mainly used for water supply and drainage of water plants, power plants, steel smelting, papermaking, chemical industry, water source engineering, environmental facilities construction and other systems.
It can be used as the transformation of old pipelines, maintenance and replacement of supporting valves, especially suitable for the use of regulating and intercepting equipment on Waterway pipelines.

Product features:

Reasonable design, compact structure, 90 ºC rotation, flexible opening and closing.

The eccentric structure is adopted, and the sealing pressure is automatically established between the sealing pairs to reduce the friction of the sealing ring and prolong the service life of the valve.

The sealing structure has no mechanical connection and can adapt to severe working conditions. Completely sealed with zero leakage. The valve seat has strong erosion resistance.

The sealing performance of the expansion part is reliable, and the installation and disassembly are convenient. It can adapt to a certain amount of pipeline dislocation and inclination. No welding is required for the connection with pipeline.

Product executive standard:

The product meets the standard of GB 12238-89 "universal valve flange and clamp connection butterfly valve".

The test is in accordance with GB / T13927-92 "pressure test for general purpose valves".

The side flange connection meets the standard of GB / T 17241.6-98 gray cast iron pipe flange and gasket. At the same time, the flange connection standards of PN1.0MPa and PN1.6MPa in bs4504, iso2084 and din2501 are met.
