Description

Flanged Butt Weld Butterfly Valve , Double Eccentric Lug Type Butterfly Valve

Butterfly Valve 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 .
