Triple Eccentric Butterfly Valve Size: 3”~72” Standard: ANSI B16.5, ANSI B16.34/16.47, ANSI/FCI 70-2, MSS SP-25/61/68, API 598/609/607, PED, ISO 5208/5211/5752/9001 Face to Face:  API 609, ISO 5752 Pressure Rating: ANSI 150, 300LB, 600LB Material: Carbon Steel, Stainless Steel, Duple Stainless Steel Butterfly Valve Design Feature - Medium can flow through the body directly for little resistance and high flow capacity. - The body and upper cover could be made of carbon steel,austenitic stainless steel or special alloy material. - The sulfur-free flexible v-graphite is heat resisting,we shall ensure the service life of packing is long-term without maintenance by increasing pre-pressure on spring gasket. - The self-sealing packing structure is tested 100,000 times (full travel) to ensure zero leakage .When the stem moves at low friction state,we can get the long-term steady precision of control valve . - The seat adopts multi-level structure, the sealing surface is composed of metal and special non-metal materials to ensure zero leakage. - The shaft center deviates from the valve center bidirectionally. The asymmetric design sealing surface allows the disc to revolve in 0-90° freely.
