Product Description

Description

High Quality Butterfly Valve

A butterfly valve is a rotary valve(quarter turn valve)using a disc as the closure member.Butterfly valves can be eithersymmetric or eccentric (=offset),the latter referring to the stem being displaced from the center of the disc.

Body:WCB,CF8M Bonded with NBR or EPDM

Disc:ASTMA53665-45-12 Nylon coated,CF8,CF8M,2507,1.4462Stem:SS420,SS431Body style:Flange

Nominal diameter.2?-88?(DN50mm-DN2000mm)Top flange:ISO5211Operating pressure:16bar for DN50-DN300,10bar for DN350-DN2200
 

Description

Double flanged butterfly valve features a bonded liner extending over the flanges.The double flange design is suitable for high pressure loadingand for use in heavy industry,shipbuilding,severe vacuum applications and water treatment industry like potable water,water treatment andwastewater applications.
