Butterfly Valve FEATURES

Metal seated, good seal
Low weight
Low flow resistance
Small operation torque

Butterfly Valve Characteristics:

It is simple structure : good interchangeability and low price

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

Overall support is good ,stable and solid

Use less rubber of seat ,so expansion has sm

all impaction and easy to control torque value at an appropriate range .`
Applying to two pieces of no-sells connection ,structure is simple and convenient to be maintained
Butterfly disc owns automatic alignment function and achieved small combination of disc and seat .
Phenolic back seat is featured such as no loss ,tensile ,anti-leak ,convenient replacement etc.
For seat sealing surface and phenolic back as a whole ,it can reduce amount of deformation .
