feature
1. High pressure and high temperature zero leakage sealing: Adopting a whole forged steel valve body and metal hard sealing structure, the sealing surface of the valve disc and valve seat is welded with hard alloy. Through self tightening sealing design, the sealing ratio is dynamically enhanced under the action of medium pressure, achieving a sealing grade of ANSI Class VI or above, suitable for absolute cutting requirements in high temperature, high pressure and supercritical working conditions.
2. Fully forged steel structure and high-strength corrosion resistance: The valve body is made of forged steel materials such as ASTM A105 and A182, which are integrally forged without the risk of casting defects. The grains are dense and uniform, and have excellent impact resistance, high-temperature creep resistance, and hydrogen sulfide stress corrosion resistance. The highest applicable temperature can reach 593 ℃ (depending on the material grade).
3. Compact design and permanent connection: using socket welding or threaded connection, the structure is compact and the connection strength is high, eliminating potential leakage points of flange connection, especially suitable for high-pressure small-diameter pipeline systems, saving installation space and improving the overall sealing reliability of the system.
4. Anti erosion and long-life guidance: The valve disc and seat adopt a symmetrical conical sealing fit, and the flow direction of the medium is designed reasonably, effectively reducing the erosion of the sealing surface by high-speed fluid; The valve stem is equipped with a guide bushing to ensure precise alignment during the opening and closing process, avoid eccentric wear of the sealing surface, and extend its service life.
5. Multiple drive and intelligent control adaptation: supports manual, gearbox, electric or pneumatic drive, the threaded part of the valve stem is hardened, and the opening and closing torque is stable; Configurable intelligent actuators and position feedback devices enable precise control of opening, remote automation operation, and fault diagnosis functions.
6. Strong specificity for harsh working conditions: Designed specifically for high-temperature and high-pressure steam, oil and gas, and corrosive medium pipelines in industries such as power, petrochemicals, and nuclear power, it maintains sealing stability even under frequent opening and closing, and severe temperature and pressure fluctuations. It is the core preferred valve for high-temperature and high-pressure cut-off systems.
