Introduction

1. Wafer type rubber lined butterfly valve body is rubber lined internally , the disc adopts anticorrosive material such as chrome plated ductile cast iron,stainless steel ,copper alloy etc,therefore the wafer type rubber lined butterfly valve can resist corrosion .

2. Wafer type rubber lined butterfly valve has centric structure,bi-directional seal , which can be assembled in either direction , not limited by direction of the medium flow .

3. Wafer type rubber lined butterfly valve is wafer type ,short size,small volume, light weight and space-saving .

4. Wafer type rubber lined butterfly valve adopts sectional axis design , thin disc , low flow resistance .
