Stop Valve J61Y-40C for Dada Dhuniwale Power Plant｜YOYIK

Stop Valve J61Y-40C for Dada Dhuniwale Power Plant｜YOYIK
Product Introduction

As a manual lift globe valve, the J61Y-40C Stop Valve features a precision casting structure, with WCB carbon steel (designated by suffix C) serving as its primary body material. Rated at PN40 (4.0MPa nominal pressure) and equipped with a manual lifting stem, it is specially designed for power generation facilities and thermal power plants, ideally suited for medium-pressure pipeline systems where dependable pressure resistance and leak-tight media shut-off are required.

Designed specifically for Dada Dhuniwale Power Plant and other thermal power stations globally, this stop valve is compatible with media like saturated steam, feedwater, and light oil under medium-temperature and medium-pressure operating conditions. Operating at a maximum temperature of ≤425℃ and pressure of ≤4.0MPa (consistent with PN40 rating), it provides reliable, accurate on-off control for both auxiliary pipelines and instrument loops, fully complying with the operational requirements of medium-pressure power plant scenarios.

Company Profile

YOYIK specializes in manufacturing industrial stop valves and power plant equipment, catering to the global energy industry. We focus on the design, research, development, and production of medium and high-pressure stop valves (including the PN40C series), supported by a stringent quality management system and an extensive global service network to fulfill various customer needs.

Product Features & Operation Points

- PN40 (4.0MPa) Medium-Pressure Rating: Custom-engineered for medium-pressure pipeline networks in thermal power plants, this valve effectively handles the impact of medium-pressure media, ensuring leak-free and stable operation in medium-temperature and medium-pressure environments.

- Dependable Shut-Off Capability: Featuring a precision-ground conical sealing surface between the valve disc and seat, it achieves tight, long-lasting media shut-off to prevent leakage—critical for safeguarding the safety and stability of medium-pressure pipeline systems in power plants.

- Superior WCB Carbon Steel (Suffix C): Made from high-grade WCB carbon steel (matching suffix C), the valve offers good high-temperature resistance (up to 425℃), reliable mechanical strength, and excellent processability. It is ideal for long-term use in medium-pressure steam and feedwater pipelines of power plants, providing high cost-efficiency.

- Stable Sealing & User-Friendly Operation: Equipped with metal-to-metal seating and high-temperature resistant packing, it ensures long-term stable sealing and wear resistance under medium-pressure conditions. The manual lifting stem with precision threads enables smooth operation, allowing for accurate control of the valve’s opening and closing status.

- International Standard Compliance & Easy Maintenance: Manufactured in line with international standards (API 598, ASME B16.34, GBT), it is fully compatible with global power plant equipment. Its top-mounted structure allows for on-site inspection and maintenance, minimizing equipment downtime and reducing maintenance expenses.
