Stop Valve J61H-25 A105 for Durgapur Steel Power Plant｜YOYIK
2. Product Introduction
YOYIK Stop Valve J61H-25 A105 is a medium-high pressure stop valve with PN25 (2. 5MPa) nominal pressure, adopting straight-through structure, threaded connection and manual operation. It is made of high-quality A105 carbon steel, featuring hard seal (H suffix), specially designed for steel plant power systems and medium-high pressure power generation facilities.
It is mainly applied to medium isolation in medium-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 425℃ and the maximum working pressure is 2. 5MPa, which perfectly matches the working conditions of Durgapur Steel 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 medium-high pressure stop valves, with products widely used in steel plant power systems, thermal power, chemical and steel industries, providing high-quality spare parts for power plants including Durgapur Steel Power.
4. Product Features & Operation Points
1. PN25 medium-high pressure design: Precision-forged A105 carbon steel valve body can withstand 2. 5MPa working pressure, meeting the medium-high pressure pipeline isolation needs of Durgapur Steel Power Plant and ensuring no leakage during long-term operation.
2. Hard seal (H suffix): metal-to-metal seating with high-strength hard seal between valve core and seat, combined with A105 carbon steel body, realizes zero-leakage medium cut-off and ensures the stability of Durgapur Steel Power Plant pipeline systems.
3. High-quality A105 carbon steel material: The forged A105 carbon steel body has 425℃ high-temperature resistance, strong wear resistance and good structural stability, which can adapt to the harsh medium-high pressure working environment of Durgapur Steel Power Plant and extend the service life of the valve.
4. Straight-through structure & easy manual operation: Straight-through design ensures smooth medium flow and small flow resistance; threaded connection is compact, suitable for narrow installation spaces of Durgapur Steel Power Plant equipment; medium-high pressure adaptive torque handle, labor-saving to operate and convenient for disassembly.
5. Standard compliance & strict safety testing: Complies with GBT 12235 and API 602 standards, passes strict non-destructive testing (NDT) and medium-high pressure tests; the A105 carbon steel structure has good spare part interchangeability, reducing maintenance costs for Durgapur Steel Power Plant.
