Stop Valve J41J-64 for Thermal Power Plant Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41J-64 is a high-pressure carbon steel stop valve with PN64 (≤6.4MPa) nominal pressure, adopting a straight-through structure, flange connection and manual operation. It is specially developed for medium isolation in high-pressure systems of power generation facilities and thermal power plants, focusing on scenarios that require high pressure-bearing capacity and tight sealing. Made of high-quality carbon steel (matching the "C" suffix), it has excellent structural stability and can adapt to the harsh high-temperature and high-pressure working conditions of industrial sites.

It is mainly used for medium isolation in high-pressure auxiliary pipelines, steam pipelines and instrument loops of thermal power plants, compatible with high-temperature steam, high-pressure water, hydraulic oil and other industrial media. With a maximum working temperature of 450℃ and a maximum working pressure of 6.4MPa (consistent with PN64), it can stably cope with the high-pressure and frequent temperature fluctuation working conditions of power plant high-pressure systems, ensuring the safe and efficient 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 R&D, production and customization of power plant auxiliary pipeline valves, with products widely used in thermal power, chemical and steel industries.

4. Product Features & Operation Points

1. PN64 high-pressure design: The integral forging carbon steel valve body is professionally engineered to withstand 6.4MPa working pressure, fully meeting the medium isolation requirements of high-pressure pipelines and instrument loops in thermal power plants, and ensuring no deformation or leakage under long-term high-pressure operation.

2. High-precision medium isolation function: Equipped with a precision-machined valve core and valve seat, it can achieve rapid, tight and stable medium cut-off during equipment maintenance or pipeline faults, effectively preventing high-pressure medium backflow and avoiding major safety hazards in power generation facilities.

3. High-performance carbon steel material: Adopting high-quality carbon steel through integral forging and professional heat treatment, it has excellent high-temperature resistance (up to 450℃) and wear resistance, which can adapt to the harsh working environment of thermal power plant high-pressure systems and greatly extend the service life of the valve.

4. High-pressure sealing and labor-saving operation: Adopts enhanced metal-to-metal seating sealing structure, which improves sealing performance under high-pressure conditions and completely avoids medium leakage; the manual operation structure is optimized, with reasonable torque design, labor-saving and easy to operate, suitable for narrow installation spaces of high-pressure equipment.

5. Standard compliance and easy maintenance: Complies with GBT 12235 and API 602 international standards, undergoes strict non-destructive testing (NDT) and high-pressure test before delivery to ensure product qualification; the valve structure is optimized for disassembly and assembly, with good spare part interchangeability, and daily maintenance only requires regular inspection of sealing performance.
