Wafer Type Fully Lined PTFE Butterfly Valve

Product Introduction

The Wafer Type Fully Lined PTFE Butterfly Valve is a soft-sealing valve designed for highly corrosive media such as acids, alkalis, salts, and strong oxidizing agents.

Its body, disc, and seat are all fully lined with PTFE (or other fluoroplastic materials such as PFA, FEP), ensuring complete isolation between the metal body and the process fluid.

This valve features excellent corrosion resistance, reliable sealing performance, and minimal torque operation. It is widely used in chemical, pharmaceutical, chlor-alkali, acid-making, and environmental protection systems, providing a reliable solution for harsh corrosive applications.

Product Features and Advantages

Full Lining Protection: The valve body and disc are completely covered with PTFE, PFA, or FEP to ensure zero metal exposure.

Excellent Corrosion Resistance: Suitable for almost all corrosive fluids including hydrochloric acid, sulfuric acid, nitric acid, and strong alkalis.

Soft Seat Sealing: The resilient fluoroplastic seat ensures bubble-tight sealing performance under Class 150 pressure conditions.

Low Operating Torque: The smooth PTFE surface reduces friction and provides easy manual or automated operation.

Compact Wafer Type Design: Lightweight and easy to install between flanges, suitable for both horizontal and vertical pipelines.

Maintenance-Free: The fluoroplastic lining resists aging, scaling, and contamination, reducing maintenance frequency.

Flexible Actuation Options: Can be operated manually, or equipped with pneumatic or electric actuators.
