Gas Valve for Accumulator NXQ1-L40 31.5 H-CQF｜YOYIK

Gas Valve for Accumulator NXQ1-L40/31.5/H-CQF for Kakatiya Power Plant｜YOYIK
Product Introduction

The product is a gas valve for accumulator of model NXQ1-L40/31.5/H-CQF, featuring one-way sealing structure, gas charging and discharging control operation, nominal pressure PN31.5 (≤31.5MPa), made of A182 F316/CF8M stainless steel valve core and fluorine rubber sealing ring, specifically designed for power generation facilities, thermal power plants and matching with NXQ series hydraulic accumulators in power station EH systems.

It is mainly applied in the gas charging, discharging and sealing control scenarios of Kakatiya Power Plant and other thermal power plants, suitable for matching with NXQ1-L40/31.5/H-CQF series hydraulic accumulators in power plant turbine EH hydraulic systems, feedwater pump hydraulic circuits and instrument loops, capable of withstanding maximum operating pressure of 31.5MPa and maximum operating temperature of 150℃, matching the hydraulic working conditions of power plant accumulators, and ensuring reliable gas control and sealing performance.

Company Profile

It focuses on the design, R&D and production of high-demand gas valves for accumulators and power plant hydraulic accessories, and its products are widely used in power, chemical and steel industries, with a complete quality management system and global service network.

Product Features & Operation Points

- Designed with nominal pressure PN31.5 (maximum operating pressure ≤31.5MPa) and maximum operating temperature 150℃, it can adapt to the hydraulic working conditions of Kakatiya Power Plant and other thermal power plants, perfectly matching NXQ1-L40/31.5/H-CQF accumulators, ensuring stable gas control and sealing performance and no leakage.

- Adopts one-way sealing structure and gas charging/discharging integrated control, with quick response speed and reliable sealing performance, which can effectively control the gas flow in accumulators, realize safe charging and stable pressure maintaining, and ensure the normal operation of power plant EH hydraulic systems.

- The valve core is made of A182 F316/CF8M stainless steel and the sealing ring is made of fluorine rubber, which has excellent corrosion resistance, high temperature resistance and pressure resistance, suitable for nitrogen (common gas for accumulators) and EH hydraulic oil environment in power plant systems, ensuring long service life.

- Equipped with precise thread connection design, fully compatible with NXQ1-L40/31.5/H-CQF accumulator gas ports, easy to install, disassemble and maintain, reducing the maintenance time of power plant accumulator systems and improving equipment maintenance efficiency.

- Complies with API 6D and GB/T 12224 standards, with strict quality control in the production process, high consistency of product size and performance, and low later replacement cost, adapting to the standardized operation requirements of power plant equipment and power generation facilities.
