Stop Valve J41Y-63V for Lalitpur Power Plant｜YOYIK
2. Product Introduction
YOYIK Stop Valve J41Y-63V is a high-pressure stop valve with PN63 (6. 3MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. It is made of high-quality chrome-vanadium alloy steel (V suffix), specially designed for thermal power plants and power generation systems.
It is mainly applied to medium isolation in high-pressure auxiliary pipelines, steam pipelines and instrument loops of power generation facilities, compatible with high-temperature steam, water and hydraulic oil. The maximum working temperature is 520℃ and the maximum working pressure is 6. 3MPa, which perfectly matches the working conditions of Lalitpur 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 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. PN63 high-pressure design: Precision-forged chrome-vanadium alloy steel valve body can withstand 6. 3MPa working pressure, meeting the high-pressure pipeline isolation needs of Lalitpur 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 chrome-vanadium alloy steel, realizes zero-leakage medium cut-off and ensures the stability of power generation facilities pipeline systems.
3. Chrome-vanadium alloy steel (V suffix): The forged steel body has 520℃ high-temperature resistance, strong corrosion resistance and wear resistance, which can adapt to the harsh working environment of thermal power plants and extend the service life of the valve.
4. Easy manual operation: High-pressure adaptive torque design with anti-slip handle, labor-saving and easy to operate; flange connection is convenient for installation and disassembly, suitable for narrow spaces of power plant equipment.
5. Standard compliance & strict safety testing: Complies with GBT 12235 and API 602 standards, passes strict non-destructive testing (NDT) and high-pressure tests; the structure has good spare part interchangeability, reducing maintenance costs for power plants.
5. Applications
