J65Y-P55195I Stop Valve｜YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• High-pressure optimized design with a nominal pressure of P55195 (55.0MPa), precisely matching the operational demands of key high-pressure high-temperature pipelines in thermal power plants, effectively realizing reliable medium isolation and cut-off while preventing medium leakage, and eliminating cavitation risks in extremely harsh working environments.
• Scientific Y-type flow channel structure greatly reduces medium flow resistance, mitigates erosion and cavitation damage to the valve seat and clack caused by high-velocity, ultra-high temperature media, and ensures long-term stable and reliable isolation and cut-off performance in power plant pipeline systems, which is consistent with the structural advantages of high-pressure globe stop valves.
• Superior material performance: The valve body of J65Y-P55195I is made of high-quality forged alloy steel (optimized for high-temperature creep resistance and sealing performance), combined with wear-resistant alloy overlay on the valve core and seat, offering excellent pressure-bearing capacity, ultra-high temperature resistance, creep resistance, wear resistance and corrosion resistance, which is perfectly adapted to the extremely harsh high temperature and high pressure working conditions of thermal power plant pipeline systems, in line with the material selection principles of high-pressure stop valves, and ensuring long service life.
• Adopts metal-to-metal seating and precision control structure; the valve clack and seat are precision ground to achieve tight sealing effect, preventing medium leakage while ensuring smooth medium circulation when opened. The valve stem is treated with special surface treatment to reduce opening and closing friction, ensuring no external leakage during long-term operation and facilitating on-site operation and daily maintenance, which can be maintained without removing the valve from the pipeline.
• Strictly complies with international industry standards such as API 623, ASME B16.34 and GBT 12224, and all products have passed strict performance testing, ensuring excellent interchangeability with existing power plant equipment and simplifying on-site maintenance and spare part replacement processes, supported by YOYIK's exquisite production technology and high-quality manufacturing capabilities, covering the standard requirements of high-pressure stop valves.
