Stop Valve J41W-16C for Thermal Power Plant Power Plant｜YOYIK
2. Product Introduction

YOYIK Stop Valve J41W-16C is a high-hardness carbon steel stop valve with PN16 (≤1.6MPa) nominal pressure, adopting a straight-through structure, flange connection and manual operation. It is specially designed for medium isolation in power generation facilities and thermal power plants, focusing on medium-pressure scenarios that require reliable hard sealing and strong pressure-bearing capacity. Made of high-quality carbon steel (matching the "C" suffix), it features excellent structural rigidity, high-temperature resistance and wear resistance, adaptable to complex industrial medium-pressure operating environments.

It is mainly applied to medium isolation in medium-pressure auxiliary pipelines, instrument loops and steam auxiliary pipelines of thermal power plants, compatible with industrial media such as water, medium-pressure steam and hydraulic oil. With a maximum working temperature of 425℃ and a maximum working pressure of 1.6MPa (consistent with PN16), it can stably adapt to the medium-pressure, high-temperature operating conditions of power plant auxiliary systems, ensuring the tightness and safe operation of the entire 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 carbon steel hard-seal stop valves, with products widely used in thermal power, chemical and steel industries.

4. Product Features & Operation Points

1. PN16 medium-pressure design: The integral carbon steel valve body is engineered to withstand 1.6MPa working pressure, fully meeting the medium isolation requirements of medium-pressure auxiliary pipelines and instrument loops in thermal power plants, ensuring stable operation without deformation or leakage under long-term service.

2. High-strength hard sealing function: Equipped with a hard sealing (matching "W" suffix) structure between valve core and valve seat, combined with the high hardness of carbon steel, it achieves tight and durable medium cut-off, effectively preventing medium leakage even under medium-pressure, high-temperature conditions and long-term frequent on-off operations, ensuring the stability of power plant medium-pressure pipeline systems.

3. Superior carbon steel advantages: Adopting high-quality carbon steel (matching "C" suffix), it has excellent high-temperature resistance (up to 425℃) and wear resistance, strong structural rigidity, can adapt to the medium-pressure, high-temperature working environment of thermal power plants, and reduces the frequency of valve replacement.

4. Convenient manual operation: The manual operation structure is optimized with reasonable torque design, which is labor-saving and easy to operate; the flange connection method is convenient for installation and disassembly, suitable for narrow installation spaces of power plant medium-pressure auxiliary equipment.

5. Standard compliance and easy maintenance: Complies with GBT 12235 and API 602 international standards, undergoes strict non-destructive testing and pressure testing before delivery to ensure product qualification; the carbon steel structure is easy to maintain, with good spare part interchangeability, effectively reducing daily operation and maintenance costs.
