Stop Valve J41Y-40RL for Neyveli Power (Power Generation System)｜YOYIK
2. Product Introduction
YOYIK Stop Valve J41Y-40RL is a medium-high pressure stop valve with PN40 (4. 0MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. Developed specifically for Neyveli Power's power generation systems, it features hard alloy sealing (Y suffix), high-quality chrome-molybdenum stainless steel (RL suffix) material, and excellent sealing performance and pressure-bearing stability, suitable for harsh industrial working environments of Neyveli Power's power plants. Therefore, we have set strict safety standards in every link such as product design, production, and testing.
It is mainly used for medium isolation in Neyveli Power's medium-high pressure auxiliary pipelines, steam pipelines and instrument loops of power generation facilities, compatible with high-temperature steam, water and hydraulic oil in Neyveli Power's power systems. With max working temperature 550℃ and pressure 4. 0MPa, it ensures absolute tightness and safe operation of the pipeline network. We also continuously optimize safety protection measures based on actual operating conditions of Neyveli Power's projects to ensure that each product can operate stably in harsh environments.

4. Product Features & Operation Points
1. PN40 medium-high pressure design: Precision-forged chrome-molybdenum stainless steel valve body withstands 4. 0MPa pressure, meeting the medium-high pressure pipeline isolation needs of Neyveli Power's power systems, ensuring stable operation without leakage, in line with our strict safety standards.
2. Hard alloy sealing (Y suffix): High-strength hard alloy sealing between valve core and seat, combined with chrome-molybdenum stainless steel, achieves zero-leakage cut-off, ensuring stability of Neyveli Power's medium-high pressure pipeline systems and enhancing operational safety of power generation facilities.
3. Chrome-molybdenum stainless steel (RL suffix): Features 550℃ high-temperature resistance, strong corrosion resistance, wear resistance and structural stability, adapting to the harsh power plant environments of Neyveli Power, extending service life and reducing safety risks.
4. Easy manual operation: Medium-pressure adaptive torque design with anti-slip handle, labor-saving to operate; flange connection facilitates installation and disassembly, suitable for narrow spaces, ensuring safe and convenient operation.
5. Standard compliance & strict safety testing: Complies with GBT 12235 and API 602, passes strict NDT and pressure tests (in line with our strict safety standards); corrosion-resistant chrome-molybdenum stainless steel structure with good spare part interchangeability, reducing maintenance costs and safety hazards for Neyveli Power's projects.
