Gate Valve Z561H-25 WCB for North Chennai Power Plant｜YOYIK
Product Introduction

Gate Valve Z561H-25 WCB is a flange-connected, electric-operated wedge rigid gate valve (marked by model Z561), designed with a nominal pressure of PN25 (≤2.5MPa) and a valve body made of WCB carbon steel (marked by suffix H and WCB), which is widely used in power generation facilities, especially suitable for thermal power plants and related industrial pipeline systems as an on-off control component.

This gate valve is specifically matched to the working conditions of North Chennai Power Plant, mainly used for cutting off or connecting media in high-temperature, medium-pressure steam and water pipelines, with a maximum working temperature of ≤425℃ and good adaptability to the stable operation needs of power plant instrument loops and main pipeline systems, which can ensure the safe and smooth operation of the power generation process.

Product Features & Operation Points

- Designed with PN25 nominal pressure (≤2.5MPa) and compatible with the pressure requirements of North Chennai Power Plant’s pipeline systems, it can stably bear the medium pressure in the working process and avoid leakage risks caused by pressure mismatch.

- Adopts wedge rigid gate plate structure and electric operation (marked by model Z561), which realizes efficient and precise on-off control of media in power plant medium-pressure pipelines, effectively cuts off or connects high-temperature, medium-pressure steam and water media, and is suitable for large-caliber, automatic control pipeline installation of North Chennai Power Plant.

- Valve body is made of WCB carbon steel (corresponding to suffix H and WCB), which has excellent high-temperature resistance, wear resistance and medium-pressure-bearing capacity, adapts to the high-temperature and medium-pressure working environment of North Chennai Power Plant’s main pipelines, and has reliable performance during long-term operation under high-temperature, medium-pressure steam and water conditions.

- Equipped with electric operation, the operation is efficient, fast and labor-saving, the force transmission is stable, the opening and closing is smooth, which is convenient for remote automatic control and on-site operation coordination even for large-caliber, medium-pressure valves, reducing the difficulty of daily operation and maintenance of power plant equipment.

- Complies with GBT 12234, API and ASME standards, with complete testing procedures and reliable product quality, which is convenient for maintenance and replacement in later use, and matches the standard requirements of global power plant equipment accessories.

Applications

- Boiler water supply and drainage systems of North Chennai Power Plant

- High-temperature and medium-pressure steam pipeline systems of thermal power generation facilities

- Medium-pressure water transmission pipelines in power plant auxiliary systems

- Cooling water circulation systems of power plant turbines

- Auxiliary pipeline on-off systems of power generation equipment
