Stop Valve J561Y-1500Lb for Bandel Power Plant｜YOYIK
2. Product Introduction
YOYIK Stop Valve J561Y-1500Lb is a ultra-high pressure stop valve with 1500Lb (equivalent to PN250, 25. 0MPa) nominal pressure, adopting bellows seal structure, flange connection and manual operation. It is made of high-quality alloy steel (Lb class matching alloy material), specially designed for thermal power plants and high-pressure power generation systems.
It is mainly applied to medium isolation in ultra-high pressure auxiliary pipelines, main steam pipelines and instrument loops of power generation facilities, compatible with ultra-high temperature steam, water and hydraulic oil. The maximum working temperature is 580℃ and the maximum working pressure is 25. 0MPa, which perfectly matches the working conditions of Bandel Power Plant.
3. Company Profile
based in Deyang, YOYIK is a professional manufacturer of industrial valves and power plant equipment, focusing on R&D and production of ultra-high pressure stop valves, with products widely used in thermal power, chemical and steel industries, providing high-quality spare parts for power plants.
4. Product Features & Operation Points
1. 1500Lb ultra-high pressure design: Precision-forged alloy steel valve body can withstand 25. 0MPa working pressure, meeting the ultra-high pressure pipeline isolation needs of Bandel Power Plant and ensuring no leakage during long-term operation.
2. Hard alloy sealing (Y suffix): metal-to-metal seating with high-strength hard alloy between valve core and seat, combined with bellows seal structure, realizes zero-leakage medium cut-off and ensures the stability of power generation facilities pipeline systems.
3. Alloy steel material (1500Lb matching): The forged steel body has 580℃ high-temperature resistance, strong corrosion resistance and structural rigidity, which can adapt to the harsh ultra-high pressure working environment of thermal power plants and extend the service life of the valve.
4. Bellows seal structure & easy manual operation: Bellows seal design ensures no external leakage, suitable for high-purity medium working conditions; ultra-high pressure adaptive torque handle, labor-saving to operate; flange connection is convenient for installation and disassembly in narrow spaces.
5. Standard compliance & strict safety testing: Complies with ASME B16. 34 and API 602 standards, passes strict non-destructive testing (NDT) and ultra-high pressure tests; the structure has good spare part interchangeability, reducing maintenance costs for power plants.
5. Applications
• Thermal power plant auxiliary pipeline systems
