Stop Valve J61y 250i For Mettur Power Plant｜yoyik - China

Stop valve J61Y-250I for Mettur Power Plant｜YOYIK

2 - Product Introduction YOYIK Stop valve J61Y-250I is a stop valve with PN250 pressure class (≤25.0MPa), adopting straight-through structure, threaded connection and manual operation.

It is made of Cr-Mo alloy steel (I suffix) with Y-suffix cemented carbide seal, suitable for thermal power facilities and power generation systems.

It is used for media isolation in the plant’s pipelines (steam, water, hydraulic oil), matching its instrument loops and auxiliary pipelines with max 550℃ and ≤25.0MPa (PN250 class).

3 - Company Profile Based in Deyang, YOYIK is a leading manufacturer of industrial valves and power plant equipment in the global energy industry, focusing on the design, R&D and production of high-demand stop valves, with a complete quality management system and global service network.

4 - Product Features & Operation Points - PN250 Pressure Bearing: Cr-Mo alloy steel (I suffix) body ensures stable leak-free operation under ≤25.0MPa (PN250 class), adapting to the plant’s working conditions.

- Cemented Carbide Seal: Y-suffix metal-to-metal seal enhances wear resistance, realizing tight media cut-off for long-term high-temperature operation.

- I-suffix Cr-Mo Alloy Advantage: Excellent high-temperature (550℃) and corrosion resistance, suitable for pipeline environments of the plant.

- Straight-Through Design: Reduces flow resistance, compact threaded connection fits narrow installation spaces, easy to operate and maintain.

- Multi-Standard Compliance: Meets GBT 12235, API 602 and ASME standards, with strict testing and good spare part interchangeability.

5 - Applications • Main steam branch pipelines in Mettur Power Plant • Boiler feedwater loop isolation of the plant • Steam turbine auxiliary pipeline cut-off systems • Desuperheating water pipeline isolation in the plant • Chemical process pipeline isolation of auxiliary systems • Hydraulic control pipeline cut-off for plant equipment • Instrument protection loops in Mettur Power Plant 6 - Closing Statement Specifications and configurations can be customized according to specific project requirements.
