product details

Stainless steel CF8M pneumatic actuated butterfly valve  has smaller opening and closing torque, less opening and closing labor and better sealing performance; It is easy to open and close, labor-saving, low fluid resistance, and can be operated frequently. It has the characteristics of corrosion resistance and long service life.

1、 Structure introduction

API  standard butterfly valve adopts three eccentric structure, valve seat sealing, soft sealing PTFE, also known as polytetrafluoroethylene, is a kind of material with many corrosion resistance. Similar products are rptfe, ppl seal, our company can also produce SS304 + graphite, SS316 + graphite, or SS316 + PTFE, EPDM, NBR seal butterfly valve.

Three eccentric butterfly valve features:
1. Short structure size, small volume, light weight, easy to operate
2. Using the whole shaft mechanism, the butterfly plate has high strength and large flow area
3. The unique three eccentric design reduces the friction loss of the seal and greatly prolongs the service life

2、Relevant standards of API standard butterfly valve

Design and manufacture: API 609
Structural length: API 609
Connecting flange: ASME B16.5
Inspection and pressure test: API 598,
Actuator connection platform: ISO5211
Any valve produced by our company is pressed in strict accordance with the pressure test standard, and the zero leakage butterfly valve is allowed to leave the factory only after the pressure is qualified.
