300LB-2.5-inch American standard clamp type CF8 material metal hard seal handle butterfly valve

300LB-2.5-inch American standard clamp type CF8 material metal hard seal handle butterfly valve

【1】 Structure Introduction

The American standard butterfly valve adopts a three eccentric structure, and the valve seat seal is a metal multi-level hard seal structure, usually a sandwich layer of metal and graphite, such as 304+graphite, 316+graphite. Such hard seals can also be made into single-layer soft seals such as PTFE, RPTFE, PPL, EPDM, NBR, etc

Characteristics of Three Eccentric Butterfly Valve:

1. Short structural dimensions, small volume, light weight, and operational aspects

2. Adopting a full axis mechanism, the butterfly plate has high strength and a large overcurrent area

3. The unique three eccentric design reduces sealing friction loss and greatly extends the service life

4. Metal hard seal is resistant to high temperature, low temperature, high pressure, and has a wide range of applications
