Stop Valve J61Y-420I for Budge Budge Power Plant｜YOYIK

Stop Valve J61Y-420I for Budge Budge Power Plant｜YOYIK
Product Introduction

As a manual lift globe valve, the J61Y-420I Stop Valve features a high-strength forged structure, with Cr-Mo steel (WC6/WC9 series, corresponding to suffix I) as its core body material. Boasting a nominal pressure of PN420 (equivalent to 42.0MPa) and equipped with a manual lifting stem, it is specially customized for power generation facilities and thermal power plants, ideally suited for ultra-high-pressure pipeline systems that demand superior pressure resistance and reliable leak-tight media shut-off[4].

Exclusively developed for Budge Budge Power Plant and other large-scale thermal power stations worldwide, this stop valve is applicable to media such as superheated steam, high-temperature high-pressure water and heavy oil in harsh ultra-high-temperature and ultra-high-pressure operating conditions. It operates at a maximum temperature of ≤595℃ and pressure of ≤42.0MPa (consistent with PN420 rating), providing stable and precise on-off control for main high-pressure pipelines and critical instrument loops, which fully meets the strict operational standards of ultra-high-pressure power plant working conditions.

Company Profile

YOYIK is a professional manufacturer focusing on industrial stop valves and high-pressure power plant equipment, dedicated to serving the global energy industry. We specialize in the design, R&D and production of ultra-high-pressure stop valves (including the J61Y-420I model with Cr-Mo steel material), supported by a stringent quality control system and a comprehensive global after-sales service network to meet the high-demand requirements of customers for high-temperature and high-pressure valve products[5].

Product Features & Operation Points

- PN420 (42.0MPa) Ultra-High-Pressure Bearing Capacity: Specifically designed for ultra-high-pressure pipeline networks in large thermal power plants, this valve can effectively withstand the impact of ultra-high-pressure media, maintaining leak-free and stable operation even in extreme ultra-high-temperature and ultra-high-pressure environments, adapting to the harsh working conditions of power plants.

- Reliable Shut-Off Performance: The valve disc and seat are processed with precision-ground conical hard sealing surfaces, achieving tight and long-term media shut-off without leakage. This is crucial for protecting the safety and stability of ultra-high-pressure pipeline systems in power plants, avoiding potential safety hazards caused by media leakage.

- Excellent Cr-Mo Steel Performance (Suffix I): Made of high-quality Cr-Mo steel (WC6/WC9 series) corresponding to suffix I, the valve has superior high-temperature resistance (up to 595℃), outstanding mechanical strength and wear resistance. It is suitable for long-term service in ultra-high-pressure steam pipelines of power plants, with high durability and reliability.

- Stable Sealing & Precise Operation: Adopting metal-to-metal hard seating and high-temperature resistant graphite packing, it ensures long-term stable sealing performance and strong wear resistance even under ultra-high-pressure conditions. The manual lifting stem with precision thread design enables smooth and labor-saving operation, allowing accurate control of the valve’s opening and closing status for precise on-off adjustment.

- International Standard Compliance & Convenient Maintenance: Produced in strict accordance with international standards such as API 598, ASME B16.34 and GBT, it is fully compatible with global large-scale power plant equipment. Its top-mounted structure facilitates on-site inspection and maintenance, greatly reducing equipment shutdown time and maintenance costs, improving the operational efficiency of power plants.
