Instrument Valve J21Y-250P for Hirakud Captive Power Plant

Instrument Valve J21Y-250P for Hirakud Captive Power Plant｜YOYIK
2. Product Introduction
YOYIK J21Y-250P is a forged steel instrument valve with PN250 (≤25.0MPa) nominal pressure and A182 F304/CF8 stainless steel body, featuring straight-through structure and manual operation for high-precision isolation in power plant instrument loops.
It is specially designed for Hirakud Captive Power Plant, withstanding maximum working temperature up to 450℃ and compatible with media including superheated steam, high-pressure feedwater and chemical injection fluids, ensuring stable flow control in critical instrument sampling and monitoring systems of captive power facilities.
3. Company Profile
YOYIK is a leading manufacturer of industrial instrument valves and power plant equipment for the global energy industry, based in Deyang with strong independent R&D capabilities. The company continuously increases R&D investment, builds advanced R&D centers, and cooperates with domestic and foreign research institutions to drive technological innovation in power equipment, providing high-efficiency, low-energy-consumption solutions for captive power and other energy projects worldwide.
4. Product Features & Operation Points
PN250 high-pressure design: Integral forging valve body withstands 25.0MPa pressure, meeting Hirakud Captive Power Plant’s high-pressure instrument pipeline isolation requirements.
High-precision flow control: Precision-machined valve core ensures accurate on/off control, avoiding measurement errors in power plant instrument sampling systems.
Stainless steel advantage: A182 F304/CF8 material delivers superior corrosion resistance, adapting to corrosive chemical media in captive power plant pipelines.
Reliable sealing performance: Metal-to-metal hard sealing structure achieves zero leakage, maintaining pressure stability in instrument loops during long-term operation.
Standard compliance: Complies with GBT 12240/API 602, passes strict NDT and pressure testing before delivery, meeting quality standards of captive power facilities.
