API 609 Wafer Type Butterfly Valve,600LB,16 Inch,CF8M
The American standard butterfly valve adopts a three eccentric structure, and the valve seat is sealed with a metal multi-level hard sealing structure, usually a metal graphite interlayer, such as 304+graphite, 316+graphite. Such hard seals can also be made into single-layer soft sealing PTFE, RPTFE, PPL, EPDM, NBR, etc The characteristics of three eccentric butterfly valves:
1. Short structural size, small volume, light weight, and operational efficiency
2. Adopting a whole axis mechanism, the butterfly plate has high strength and a large overcurrent area
3. The three eccentric design of the seal reduces friction loss and greatly extends its service life
4. La tenuta dura in metallo è resistente alle alte temperature, alle basse temperature, all'alta pressione e ha un'ampia gamma di applicazioni
【2】 Relevant standards for American butterfly valves
Any valve produced by our company is strictly pressurized according to the pressure testing standards. Only after passing the pressure test can the zero leakage butterfly valve be allowed to leave the factory. Shell strength, high-pressure water sealing strength, gas sealing strength 16.5 12.1 0.6 Under the above pressure, the test can achieve zero leakage! Accept customer quality inspection and third-party quality inspection units commissioned by end customers for sampling and full inspection, but please explain to us in advance.
STV Valve is a professional manufacturer of butterfly valve series products. The company was established in 2006 with a registered capital of 11.18 million yuan. Since its establishment, we have been dedicated to researching and opening butterfly valve series products. All butterfly valve series products produced by our company now use our * molds, and regardless of the valve body wall thickness, flange thickness, and structural length, they can all meet relevant standards. Foundry molds that are not commonly used by most manufacturers in the market.
Our production scope mainly includes flange butterfly valves, clamp butterfly valves, lug butterfly valves, and welded butterfly valves. The nominal pressure ranges from PN1-100150LB-600LB, and the specifications range from DN40-1400 to NPS2-60. The standards involved include national standards, Ministry of Chemical Industry, Ministry of Machinery, as well as export standards such as American standards, German standards, Japanese standards, Russian standards, and English standards.
From ordinary cast steel WCB, stainless steel 304316304L, 316L, to dual phase steel 22052507, nickel aluminum bronze C95800, titanium, Hastelloy and other special steels, our company produces them all.
