Product Description
Reasonable design, compact structure, convenient disassembly and assembly, and convenient maintenance.
The eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life.
Simple and compact structure, light weight, 90° rotation, fast and flexible opening and closing.
The valve body is equipped with a foundation support, which can be installed vertically or horizontally.
Easy to install and disassemble for easy maintenance.
Soft-seal eccentric structure telescopic flanged butterfly valve is a new type of structure that integrates flanged butterfly valve and expansion joint, and is deeply trusted by users for its good performance. This product is mainly used for water supply and drainage of water plants, power plants, steel plants, petrochemicals, pharmaceuticals, food, textiles, papermaking and other systems, as the renovation and maintenance of old pipelines and replacement of matching valves, especially when water is used as a regulator and the use of water as a regulating valve.
ZFA polymer and elastomer seats provide bi-directional, drop-proof closure under vacuum and full differential pressure rating. Its unique design does not rely on pressure to assist sealing, so it seals under high and low pressures and in dirty environments. Multiple materials for optimum seat life in all applications.
For added safety, an anti-blowout shaft is standard on all valves.
Unique packaging design allows use under pressure and vacuum without modification or special assembly.
