PN64 (6.4MPa) Medium High Pressure Stop Valve J61Y-64 | YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• PN64 (6. 4MPa) Medium-High Pressure Rating: Designed in strict line with national industrial standards for PN64 pressure class, this stop valve boasts excellent medium-high pressure bearing capacity, which can effectively resist the impact of medium-high pressure media in thermal power plant pipelines, maintain leak-free and stable operation, and perfectly adapt to the medium-high pressure working conditions of thermal power plants.
• Dependable Shut-Off Performance: It adopts a precision-ground conical hard sealing structure combined with surface hardening treatment, achieving tight and long-lasting media shut-off without leakage. This is vital to ensuring the safety and stability of medium-high pressure pipeline systems in thermal power plants, avoiding potential operational risks caused by media leakage and ensuring continuous power generation operation.
• Excellent Alloy Steel Performance (Matching PN64): Made of high-quality alloy steel suitable for PN64 pressure class, the valve has outstanding high-temperature resistance (up to 425℃), excellent mechanical strength, wear resistance and corrosion resistance. It is suitable for long-term stable service in medium-high pressure steam and feedwater pipelines of thermal power plants, with high reliability and durability to adapt to long-term continuous operation needs.
• Stable Sealing & Effortless Operation: Equipped with metal-to-metal hard seating and high-temperature resistant flexible graphite packing, it ensures long-term stable sealing performance under medium-high pressure and high-temperature conditions, effectively preventing media leakage and external impurities from entering the valve body. The manual lifting stem with precision threads operates smoothly and labor-savingly, allowing accurate control of the valve's opening and closing status to meet the precise on-off needs of thermal power plant pipeline systems.
• Standard Compliance & Easy Maintenance: Strictly manufactured in accordance with international and national industrial standards such as API 598 and HG/T 20592, it is fully compatible with global large-scale thermal power plant equipment. Its top-mounted structure facilitates on-site inspection and maintenance, effectively reducing equipment shutdown time and maintenance costs, and ensuring the continuous and stable operation of thermal power plants.
