900LBR (15.51MPa) Medium High Pressure Stop Valve J61Y-900LBR | YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• 900LBR (15.51MPa) Pressure Class Compliance: As a core advantage of the J61Y-900LBR stop valve, it adheres strictly to the ASME B16.5 American Standard for 900LBR pressure rating, delivering reliable medium-high pressure bearing capacity. It can effectively withstand the impact of high-pressure media in thermal power plant pipelines while maintaining leak-tight and stable operation, perfectly adapting to the medium-high pressure working environment of thermal power generation.
• Superior Shut-Off Dependability: Adopting a precision-ground conical hard seal integrated with surface hardening technology, the valve achieves tight, long-lasting media shut-off without leakage. This critical performance ensures the safety and stability of medium-high pressure pipeline systems, avoids operational risks caused by media leakage, and supports uninterrupted power generation operations.
• Premium Alloy Steel for 900LBR (15.51MPa) Class: Fabricated from high-quality alloy steel that meets the 900LBR (15.51MPa) pressure class requirements of the J61Y-900LBR stop valve, it possesses exceptional high-temperature resistance (up to 538℃), along with strong mechanical strength, wear resistance and corrosion resistance, ensuring long-term reliable service in medium-high pressure pipelines of thermal power plants.
• Reliable Sealing & Effortless Operation: Equipped with metal-to-metal hard seating and high-temperature resistant flexible graphite packing, the valve maintains stable sealing performance under medium-high pressure and high-temperature conditions, preventing media leakage and impurity ingress. Its precision-threaded manual stem enables smooth, labor-saving operation, allowing for accurate on-off control of pipeline systems.
• International Standard Compliance & Easy Maintenance: Manufactured in strict accordance with API 598, ASME B16.34 and other international and American standards, the valve is fully compatible with global large-scale thermal power plant equipment. Its top-mounted design simplifies on-site inspection and maintenance, effectively reducing equipment downtime and maintenance costs.
