Wafer Type Butterfly Valve

Design Description:

– Low friction between seat and disc of valve

– “”Zero Leakage””Sealing Design

– One Piece Shaft

– Low torque enables the compact actuator and a long cycle life

– Blow-out proof shaft

– Optional stem extension

– Optional locking device  fdafadf

– Concentric rubber lined butterfly valve isolates the valve body from the media,using superiorly anti corrosive polymer material.


Qualification certifacation

Concentric butterfly valves are manufactured to the latest edition of EN593 and tested to API Standard 598 Or EN12266.


Soft seat butterfly widely apply to all kinds of indutrial control system, it has many

advantages such as light weight, low cost, high sealed compared to other normal valves.Its

high sealed and anti-corrosion property can extended usage life.It is one of most economic

choice under the low and low and medium pressure. 

Nowdays the butterfly valves is widely used in drainage system and flo contrlo system.
