product details
300lb-6 inch worm gear lug butterfly valve is a kind of commonly used butterfly valve, which is widely used in water conservancy, petroleum, chemical industry and other industries. It has obvious advantages, simple structure, good sealing performance, light operation, side corrosion, high temperature resistance, convenient operation, flexible, safe and reliable use.
1、 Structure introduction
Convex butterfly valve, also known as branch butterfly valve, American standard convex butterfly valve adopts three eccentric structure, and the valve seat is sealed by metal multi-layer hard valve Sealing structure, usually metal and graphite interlayer, such as 304 + graphite, 316 + graphite, such as hard seal, also can be usedPTFE, rptfe, ppl, EPDM, NBR, etc
Three eccentric butterfly valve features:
1. Short structure size, small volume, light weight, easy operation
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
4. Metal hard seal is resistant to high temperature, low temperature and high pressure, and has a wide range of applications
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 strength | Sealing strength of high pressure water | Air seal strength |
| 7.5 | 5.5 | 0.6 |
Under the above pressure, the zero leakage can be achieved.
Accept the sampling and full inspection of the third party quality inspection unit entrusted by the customer and the end customer, but explain to us in advance
3、Detailed connection size
| Nominal pressure | Nominal size | Structural length | Drilling center distance | aperture | |
| 300 LB | NPS 6 | 59 | 269.9 | 12 |
