Stop Valve J61H-300LB for Suratgarh Power Plant｜YOYIK
2. Product Introduction
YOYIK Stop Valve J61H-300LB is an ultra-high pressure stop valve with 300LB (equivalent to PN50, 5. 0MPa) nominal pressure, adopting straight-through structure, threaded connection and manual operation. It is made of high-quality alloy steel (300LB class matching high-strength alloy material), featuring hard seal (H suffix), specially designed for thermal power plants and ultra-high pressure power generation facilities.
It is mainly applied to medium isolation in ultra-high pressure auxiliary pipelines, steam pipelines and instrument loops of power generation facilities, compatible with ultra-high temperature steam, water and hydraulic oil. The maximum working temperature is 520℃ and the maximum working pressure is 5. 0MPa, which perfectly matches the working conditions of Suratgarh 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 including Suratgarh Power.
4. Product Features & Operation Points
1. 300LB ultra-high pressure design: Precision-forged alloy steel valve body can withstand 5. 0MPa working pressure, meeting the ultra-high pressure pipeline isolation needs of Suratgarh 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 alloy steel body, realizes zero-leakage medium cut-off and ensures the stability of Suratgarh Power Plant pipeline systems.
3. High-quality alloy steel material (300LB matching): The forged alloy steel body has 520℃ high-temperature resistance, strong corrosion resistance, wear resistance and excellent structural rigidity, which can adapt to the harsh ultra-high pressure working environment of Suratgarh 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 Suratgarh Power Plant equipment; ultra-high pressure adaptive torque handle, labor-saving to operate and convenient for disassembly.
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 alloy steel structure has good spare part interchangeability, reducing maintenance costs for Suratgarh Power Plant.
