Product Introduction
Application Of Clamp Type PTFE Valve Seat Eccentric Butterfly Valve
This Butterfly Valve Is Suitable For Opening And Closing Directional Control Of Medium Flow In Pipelines Of Petroleum, Chemical, Metallurgical, Power, Municipal Engineering, Water Plants And Other Media With A Medium Temperature ≤ 180 ℃.
Characteristics Of Clamp Type PTFE Valve Seat Eccentric Butterfly Valve
1. This Butterfly Valve Has The Characteristics Of Reasonable Structure, Easy And Flexible Opening And Closing, And Convenient Maintenance And Use.
2. The Valve Seat Is Made Of Polytetrafluoroethylene.
3. This Butterfly Valve Adopts A Double Eccentric Structure. When The Butterfly Plate Is Opened From 10 To Fully Open, The Valve Seat And Butterfly Plate Are Completely In A Non-contact State. When The Valve Is Closed, The Butterfly Plate Rotates With The Valve Stem And Deflects Into The Valve Seat, Making The Sealing Ring Of The Butterfly Plate Valve Seat Almost Frictionless And Achieving Sealing, Thereby Avoiding Wear On The Sealing Surface And Extending The Service Life.
4. Separate Assembly Of Sealing Seat. Easy To Adjust And Repair.
5. Small Size, Light Weight, Simple And Reasonable Structure, Easy To Use And Install.
