product details

Butterfly valve ss connection with ISO5211 platform  has good regulation performance. The connection between actuator and valve adopts international standard. According to this standard, customers can configure manual, electric, pneumatic and other operation modes.

1、 Structure introduction

API standard butterfly valve adopts three eccentric structure. The valve seat is sealed with gold layer hard seal structure, which is usually metal and graphite layer, such as 304 + graphite, 316 + graphite. Such hard seal can also be made into single-layer soft seal PTFE, RPTFE, PPL, EPDM, NBR, etc

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.
