Design Featurer
Body sealing surface: It could be processed on the body directly, and the surface could be covered alloy material and higher hardness material, such as tungsten carbide.
Disc sealing surface: It has two kinds of seal structure, multi-layer seal and full metal seal. The multi-layer seal is divided into graphite seal and PTFE seal. The full metal seal includes metal to metal seal and high strength surfacing materials seal. We can make the appropriate choice according to different condition.
Standard
Valve body is designed to meet IEC60534-3-1-2001 and GBAT 12221-2005 API609
Valve mounting flange shall be per ISO 5211
Flange Standard: JB/T79.1-94,JB/T79.4-94,HG20616-97,ANSI B16.5,ANSI B16.47
The highest pressure: Class600/6.3Mpa, Temperature range: -196 ~ 538°C
Shell Testing: The shell strength is designed to meet ASME B16.34 and GB/T9092-1999
Leak standard: ANSI B16.104
Main 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 and constant friction.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 bi-directionally. The asymmetric design sealing surface allows the disc to revolve in 0-90° freely
