Stop Valve J41J-16C for Thermal Power Plant Power Plant

Stop Valve J41J-16C for Thermal Power Plant Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41J-16C is a carbon steel stop valve with PN16 (≤1.6MPa) 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 accumulator auxiliary pipelines and hydraulic systems. 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 accumulator pressure maintaining systems and hydraulic auxiliary pipelines of thermal power plants, compatible with hydraulic oil, water and other industrial media, with a maximum working temperature of up to 425℃ and maximum working pressure consistent with the nominal pressure PN16. It coordinates with NXQ-A-25/20-LY gaskets to match the harsh working conditions of power plant instrument loops and auxiliary pipeline systems, ensuring stable system operation.

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. PN16 pressure design: The integral carbon steel valve body can withstand 1.6MPa working pressure, which meets the medium isolation demand of thermal power plant accumulator auxiliary pipelines and ensures stable pressure-bearing performance under long-term operation.

2. Core matching function: It is perfectly matched with NXQ-A-25/20-LY gaskets, which can effectively solve the pressure loss problem of accumulators caused by gasket failure, and ensure the stable operation of power plant accumulator pressure maintaining systems.

3. Carbon steel material advantage: Adopting high-quality carbon steel, it has good wear resistance and adaptability to industrial working environments, which can reduce the frequency of product replacement and lower the operation and maintenance cost of power plants.

4. Sealing & operation design: Equipped with high-quality sealing structure, it cooperates with NXQ-A-25/20-LY gaskets to realize double sealing protection, preventing medium leakage; 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 before delivery; when matching with NXQ-A-25/20-LY gaskets for maintenance, no special tools are needed, only a flathead screwdriver is required to complete gasket replacement, improving maintenance efficiency.
