Stop Valve J61Y-420 for Wardha Warora Power Plant｜YOYIK

Stop Valve J61Y-420 for Wardha Warora Power Plant｜YOYIK
Product Introduction

Classified as a manual lift globe valve, the J61Y-420 Stop Valve adopts a high-strength forged structure, with high-pressure alloy steel as its primary body material. With a nominal pressure of PN420 (equivalent to 42.0MPa) and a manual lifting stem, it is customized for power generation facilities and thermal power plants, perfectly suited for ultra-high-pressure pipeline systems that require exceptional pressure resistance and absolute leak-tight media shut-off.

Custom-developed for Wardha Warora Power Plant and other large-scale thermal power stations across the globe, 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 ≤570℃ and pressure of ≤42.0MPa (in line with PN420 rating), delivering consistent and precise on-off control for main high-pressure pipelines and critical instrument loops, fully meeting the strict operational standards of ultra-high-pressure power plant working conditions.

Company Profile

YOYIK is a professional supplier focusing on industrial stop valves and high-pressure power plant equipment, serving the global energy industry. We dedicate ourselves to the design, R&D and production of ultra-high-pressure stop valves (including the J61Y-420 model), supported by a strict quality control system and a global after-sales service network to meet the high-demand requirements of customers.

Product Features & Operation Points

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

- Absolute Shut-Off Reliability: The valve disc and seat are equipped with a precision-ground conical hard sealing surface, achieving tight and long-term media shut-off without leakage, which is vital for protecting the safety and stability of ultra-high-pressure pipeline systems in power plants.

- Superior High-Pressure Alloy Steel Performance: Crafted from high-quality high-pressure alloy steel, the valve possesses excellent high-temperature resistance (up to 570℃), outstanding mechanical strength and wear resistance, making it 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 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.

- International Standard Compliance & Efficient Maintenance: Produced in 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.
