Stop Valve J41J-25 for Thermal Power Plant Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41J-25 is a carbon steel stop valve with PN25 (≤2.5MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation, which is widely used in power generation facilities and thermal power plants for medium isolation in auxiliary pipelines and instrument loops. It is made of carbon steel (matching the "C" suffix), with stable structural performance and strong adaptability to industrial working conditions.

It is mainly applicable to auxiliary pipelines and instrument loop systems of thermal power plants, compatible with water, steam, hydraulic oil and other industrial media, with a maximum working temperature of up to 425℃ and maximum working pressure consistent with the nominal pressure PN25. It matches the harsh working conditions of power plant auxiliary systems and instrument loops, ensuring stable and efficient operation of the whole pipeline system.

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. PN25 pressure design: The integral carbon steel valve body can withstand 2.5MPa working pressure, which meets the medium isolation demand of thermal power plant auxiliary pipelines and instrument loops, ensuring stable pressure-bearing performance under long-term operation.

2. Core isolation function: It has efficient medium cut-off and isolation performance, which can quickly cut off the medium circulation in case of pipeline or equipment failure, avoiding fault expansion and protecting the safety of power generation facilities.

3. Carbon steel material advantage: Adopting high-quality carbon steel, it has good high-temperature resistance and wear resistance, adapting to the high-temperature and high-pressure working environment of thermal power plants, reducing the frequency of product replacement and operation and maintenance costs.

4. Sealing & operation design: Equipped with reliable metal-to-metal seating sealing structure, effectively preventing medium leakage and ensuring pressure stability of pipeline systems; manual operation is simple and easy to master, suitable for narrow installation spaces of power plant auxiliary equipment.

5. Maintenance & standard compliance: Complies with GBT and API standards, passes strict pressure testing and quality inspection before delivery; the product structure is compact, with good interchangeability, and daily maintenance only needs regular inspection of sealing performance, which is convenient and efficient.
