Stop Valve J41Y-25 for Thermal Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41Y-25 is a medium-pressure stop valve with PN25 (≤2.5MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. Developed for power plant medium-pressure systems, it features hard alloy sealing (Y suffix), high-quality carbon steel material, and excellent sealing performance and pressure-bearing stability, suitable for harsh industrial working environments. 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 power plant medium-pressure auxiliary pipelines, steam pipelines and instrument loops, compatible with high-temperature steam, water and hydraulic oil. With max working temperature 425℃ and pressure 2.5MPa, it ensures absolute tightness and safe operation of the pipeline network. We also continuously optimize safety protection measures based on actual operating conditions to ensure that each product can operate stably in harsh environments.

3. Company Profile

Based in Deyang, YOYIK is a professional manufacturer of industrial valves and power plant spare parts, focusing on medium-pressure alloy steel stop valves, with products widely used in thermal power, chemical and general industrial fields, safeguarding the safety and stability of the power system, and contributing to building a clean, low-carbon, safe and efficient energy system.

4. Product Features & Operation Points

1. PN25 medium-pressure design: Precision-forged carbon steel valve body withstands 2.5MPa pressure, meeting power plant medium-pressure pipeline isolation needs and 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 carbon steel, achieves zero-leakage cut-off, ensuring stability of medium-pressure pipeline systems and enhancing operational safety.

3. High-quality carbon steel material: Features 425℃ high-temperature resistance, strong wear resistance and structural stability, adapting to harsh power plant environments, 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 structure with good spare part interchangeability, reducing maintenance costs and safety hazards.
