Product description

YQD971J-10/16/25Q Lug Type Electrical Gear Operated Butterfly Valve, DN 2"-12", PN 1.0/1.6/2.5 MPa, Product Description Application: It is widely used in pipelines as control or throttling apparatus for supply and drainage pipeline of potable water, seawater, waste water, petrochemical industry, energy and power, shipping, food and drug, natural gas, coal gas, HVAC and fire protection systems as well as the building pipelines.   Features  l  Compact structure, convenient manufacture; l  Easy handling,90 degrees rotation with quick on/off switch; l  Stable flow regulating, good regulating characteristics; l  Low flow resistance, large fluid; l  Numbers of on/off times up to tens of thousands; long life service; l  Various type of parts materials opted for use in different medium; l  Both inner and outer surfaces of the valve body are electro-statically coated with epoxy resin powder which is environmentally friendly and non-toxic, directly applying to living and potable water, as well as food and drug industry; l  Symmetrical structure in both sides, duplex use, especially applied to in condition with duplex sealing and easy corrosion of valve body;    Full vulcanization of the valve seat:The inner surface of the valve body is encapsulated with vulcanized rubber evenly to make rubber attach the body firmly with much more reliable sealing ability. The rubber’s abrasion resistance and anti-aging abilities are greatly strengthened so that completely isolate fluid from contacting with the metal of valve body, therefore the valve having an excellent anti-corrosion ability.   Vulcanization Process    Main Parts List
