Stop Valve J41Y-100RL for Thermal Power Plant Power Plant

Stop Valve J41Y-100RL for Thermal Power Plant Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41Y-100RL is a super high-pressure alloy steel stop valve with PN100 (≤10.0MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. Developed for super high-pressure systems of power plants, it features hard alloy sealing (Y suffix), chrome-molybdenum stainless steel (RL suffix) material, and excellent high-temperature resistance, corrosion resistance and pressure-bearing stability, suitable for harsh industrial working environments.

It is mainly used for medium isolation in power plant super high-pressure auxiliary pipelines, main steam pipelines and mildly corrosive pipelines, compatible with high-temperature high-pressure steam, hydraulic oil and other media. With max working temperature 550℃ and pressure 10.0MPa, it ensures tightness and safe operation of the pipeline network.

3. Company Profile

Based in Deyang, YOYIK is a professional manufacturer of industrial valves and power plant spare parts, focusing on super high-pressure alloy steel stop valves, with products widely used in thermal power, petrochemical and steel industries.

4. Product Features & Operation Points

1. PN100 super high-pressure design: Precision-forged chrome-molybdenum stainless steel valve body withstands 10.0MPa pressure, meeting power plant super high-pressure pipeline isolation needs and ensuring stable operation without leakage.

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 super high-pressure pipeline systems.

3. Chrome-molybdenum stainless steel (RL suffix): Features 550℃ high-temperature resistance, mild corrosion resistance and strong toughness, adapting to harsh power plant environments and extending service life.

4. Easy manual operation: Upgraded torque design with anti-slip handle, labor-saving to operate; flange connection facilitates installation and disassembly, suitable for narrow spaces.

5. Standard compliance & easy maintenance: Complies with GBT 12235 and API 602, passes strict NDT and pressure tests; corrosion-resistant structure with good spare part interchangeability, reducing maintenance costs.
