product details

6-inch-150lb API standard wafer butterfly valve is used to connect the valve between the flanges of two pipes. It has the advantages of simple structure, small volume and light weight. It is composed of a few parts and materials. 6-inch-150lb API standard  wafer butterfly valve is easy to operate, only need to rotate 90 ° It has two sealing forms, metal seal and elastic seal, and has good flow control characteristics,Therefore, it is widely used in all walks of life. American Standard clip on butterfly valve is suitable for liquefied petroleum gas, gas, natural gas, hot and cold air, city gas, power generation, environmental protection, chemical refining and other system engineering. It can also be used as cutting off and regulating medium in various corrosive and non corrosive pipelines.

1、 Structure introduction

For the worm gear operation of clip type nickel aluminum bronze d95800 butterfly valve, the picture shows the nickel aluminum bronze c95800 butterfly valve, which mainly uses seawater as medium
The three eccentric soft seal structure is adopted. The butterfly plate seal material is PTFE. The same material is rptfe, 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,
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.

Shell strengthSealing strength of high pressure waterAir seal strength

Under the above pressure, the zero leakage can be achieved.
