Stop Valve J561Y-2500Lb for Pelabuhan Ratu Power Plant｜YOYIK
2. Product Introduction
YOYIK Stop Valve J561Y-2500Lb is an ultra-high pressure stop valve with 2500Lb (equivalent to PN420, 42. 0MPa) nominal pressure, adopting bellows seal structure, flange connection and manual operation. It is made of high-grade alloy steel (2500Lb class matching high-strength alloy material), specially designed for thermal power plants and ultra-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 600℃ and the maximum working pressure is 42. 0MPa, which perfectly matches the working conditions of Pelabuhan Ratu 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 Pelabuhan Ratu Power.
4. Product Features & Operation Points
1. 2500Lb ultra-high pressure design: Precision-forged high-grade alloy steel valve body can withstand 42. 0MPa working pressure, meeting the ultra-high pressure pipeline isolation needs of Pelabuhan Ratu 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. High-grade alloy steel material (2500Lb matching): The forged steel body has 600℃ high-temperature resistance, excellent corrosion resistance and high structural rigidity, which can adapt to the harsh ultra-high pressure working environment of Pelabuhan Ratu Power Plant 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 of ultra-high pressure systems; ultra-high pressure adaptive torque handle, labor-saving to operate; flange connection is convenient for installation and disassembly in narrow spaces of Pelabuhan Ratu Power Plant equipment.
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 Pelabuhan Ratu Power Plant.
