Dimensions

Characteristics:

l         It is simple structure : good interchangeability and low price

l         Stem sealing is not easy deformation ,so avoids leakage phenomenon.

l         Overall support is good ,stable and solid

l         Use less rubber of seat ,so expansion has small impaction and easy to control torque value at an appropriate range .`     

l         Applying to two pieces of no-sells connection ,structure is simple and

convenient to be maintained

l         Butterfly disc owns automatic alignment function and achieved small

 combination of disc and seat .

l         Phenolic back seat is featured such as no loss ,tensile ,anti-leak ,convenient replacement etc.

l         For seat sealing surface and phenolic back as a whole ,it can reduce amount of deformation .

Soft sealing butterfly valve is suitable for water supplying and draining

gas pipe as adjust flux and cut off medium in foodstuff ,pharmacy ,chemical

industry ,petroleum ,electric power ,light textile ,paper making etc. with

temperature <150 ℃,nominal pressure <1.6MPa.
