Product Introduction
Wafer metal sealing butterfly valve is our developing three-eccentric metal sealing butterfly valve. This product's feature such as safe and reliable, small flow block parameter, endurable high temperature, suitable for corrosive mediums etc.can be used as adjusting and shutting equipment. Extensively used in vapor, heat water, water, oil, gas, natural gas, chemicals, acid alkali salt etc technical pipeline.
Product Features
1.Reasonable design, compact construction, on-off quick. Using three eccentric metal compound taper structure, reaching no leakage under the pressure test. Minimized opening torque, sealing pair without friction work, long work life. It can suitable for different mediums while changing body materials and sealing ring compound inter layer. Reasonable taper design assure equality touch sealing.
Product Standard
1.Design Standard: JB/T8527-97.
2.Side-flange Standard:GB9115.6-10-88.
3.Face to Face:GB12221-89.
