Instrument Valve J61Y-630V for VS Lignite Power Plant｜YOYIK

Product Introduction

Company Profile

Product Features & Operation Points

• PN630 (63MPa) Ultra-High Pressure Rating: Designed in strict line with national industrial standards for PN630 pressure class, this instrument valve boasts excellent ultra-high pressure bearing capacity, which can effectively resist the impact of ultra-high pressure media in lignite power plant instrument pipelines, maintain leak-free and stable operation, and perfectly adapt to the ultra-high pressure working conditions of VS Lignite Power Plant's instrument systems.
• Dependable Shut-Off & Precision Performance: As a professional instrument valve, it adopts a precision-ground conical hard sealing structure combined with surface hardening treatment, achieving tight and long-lasting media shut-off without leakage. At the same time, it has high control precision, which is vital to ensuring the safety, stability and measurement accuracy of ultra-high pressure instrument pipeline systems in lignite-fired thermal power plants and avoiding potential operational risks caused by media leakage or control deviation.
• Excellent Cr-Mo-V Alloy Steel Performance (Suffix V): Made of high-quality Cr-Mo-V alloy steel corresponding to suffix V, the valve has outstanding high-temperature resistance (up to 595℃), excellent mechanical strength, wear resistance and corrosion resistance. It can effectively adapt to the high dust, high temperature and slight corrosive working environment of lignite-fired power plants, suitable for long-term stable service in ultra-high pressure instrument pipelines of VS Lignite Power Plant with high reliability and durability.
• Stable Sealing & Effortless Precision Operation: Equipped with metal-to-metal hard seating and high-temperature resistant flexible graphite packing, it ensures long-term stable sealing performance under ultra-high pressure and high-temperature conditions, effectively preventing dust and corrosive media from entering the valve body and affecting operation. 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 and regulation needs of VS Lignite Power Plant's instrument 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 lignite-fired thermal power plant instrument equipment. Its top-mounted structure facilitates on-site inspection and maintenance, effectively reducing equipment shutdown time and maintenance costs for VS Lignite Power Plant, and ensuring the continuous and stable operation of instrument pipeline systems.
