Stop Valve J41Y-160I for Thermal Power Plant｜YOYIK

2. Product Introduction
YOYIK Stop Valve J41Y-160I is an ultra-super high-pressure stop valve with PN160 (≤16.0MPa) nominal pressure, adopting straight-through structure, flange connection and manual operation. Developed for ultra-super high-pressure power plant systems, it features hard alloy sealing (Y suffix), chrome-molybdenum alloy steel (I suffix) material, and excellent high-temperature resistance and pressure-bearing stability, suitable for extreme industrial working environments.

It is mainly used for medium isolation in power plant ultra-super high-pressure pipelines, main steam pipelines and key auxiliary pipelines, compatible with ultra-high temperature high-pressure steam and hydraulic oil. With max working temperature 580℃ and pressure 16.0MPa, it ensures absolute tightness and safe operation of the pipeline network.

3. Company Profile

Based in Deyang, YOYIK is a professional manufacturer of industrial valves and power plant spare parts, focusing on ultra-super high-pressure alloy steel stop valves, with products widely used in thermal power, petrochemical and heavy industry.

4. Product Features & Operation Points

1. PN160 ultra-super high-pressure design: Precision-forged chrome-molybdenum alloy steel valve body withstands 16.0MPa pressure, meeting power plant ultra-super high-pressure pipeline isolation needs and ensuring stable operation without leakage.

2. Hard alloy sealing (Y suffix): High-strength hard alloy sealing between valve core and seat, combined with alloy steel, achieves zero-leakage cut-off, ensuring stability of ultra-super high-pressure pipeline systems.

3. Chrome-molybdenum alloy steel (I suffix): Features 580℃ high-temperature resistance, strong corrosion resistance and structural toughness, adapting to extreme power plant environments and extending service life.

4. Easy manual operation: Ultra-high pressure adaptive torque design with anti-slip handle, labor-saving to operate; flange connection facilitates installation and disassembly, suitable for narrow spaces.

5. Standard compliance & easy maintenance: Complies with GBT 12235 and API 602, passes strict NDT and ultra-high pressure tests; corrosion-resistant structure with good spare part interchangeability, reducing maintenance costs.
