P51110V Medium High Pressure Stop Valve J61Y-P51110V | YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• Strict Compliance with P51110V Standards: A key advantage of the J61Y-P51110V valve is its full conformity to all relevant international and industrial standards for P51110V rating. It boasts robust medium-high pressure bearing capacity, capable of effectively withstanding the impact of high-pressure media in thermal power plant pipelines while maintaining leak-free, stable operation, thus perfectly adapting to the medium-high pressure operating environment of thermal power generation.
• Reliable Shut-Off Performance: The valve adopts a precision-ground conical hard seal combined with surface hardening technology, enabling tight, long-term media shut-off without any leakage. This critical feature ensures the safety and stability of medium-high pressure pipeline systems, minimizes operational risks associated with media leakage, and supports uninterrupted power generation operations.
• Premium Cr-Mo-V Alloy (Suffix V): The J61Y-P51110V valve is fabricated from high-grade Cr-Mo-V alloy steel that meets both P51110V specifications and suffix V material standards. This material provides exceptional high-temperature resistance (up to 595℃), along with superior mechanical strength, wear resistance and corrosion resistance, ensuring long-term stable operation in thermal power plant medium-high pressure pipelines.
• Stable Sealing & Smooth Operation: Equipped with metal-to-metal hard seating and high-temperature resistant flexible graphite packing, the valve maintains consistent sealing performance under medium-high pressure and high-temperature conditions, preventing media leakage and the intrusion of external impurities. Its precision-threaded manual stem ensures smooth, labor-saving operation, allowing for precise control of the valve's on-off state in pipeline systems.
• Standard Compliance & Convenient Maintenance: Produced in strict accordance with API 598 and other relevant international and industrial standards, the valve is fully compatible with equipment in large-scale thermal power plants worldwide. Its top-mounted design simplifies on-site inspection and maintenance work, significantly reducing equipment downtime and maintenance costs.
