Wafer/Lug Type Centre Sealing Rubber Lining Butterfly Valve
Basic Info
Model No.: D71F
Product Description
Model NO.: D71F Connection Form: Wafer Seal Form: Force Sealed Work Pressure: Low Pressure (Pn<1.6mpa) Material of Seal Surface: Soft Sealed Application: Industrial Usage, Water Industrial Usage Class: 150lb to 600lb Application Fields: Metallurgy,Light Industrial,Electric Power,Petroch Trademark: NAIBANG Specification: API598, API6d, ANSI, Bs, DIN, JIS HS Code: 8481804090 Driving Mode: Manual Structure: Centre Sealing Valve Stem: Normal Working Temperature: Medium Temperature (120°CButterfly Valve
Main Features:
The turning center of the butterfly plate is on the center line of the valve body and the sealing face section of the butterfly plate. In closing, the ex-circle sealing face of the butterfly plate will extrude the valve seat made of synthetic rubber, generating elastic deformation on the seat to form an elastic force used as a sealing specific pressure so as to guarantee the tightness of the butterfly valve.
