Gate Valve Z61H-25 WCB for Sasan Ultra Mega Power Plant|YOYIK
Product Introduction
Gate Valve Z61H-25 WCB is a flange-connected, manual-operated gate valve (marked by model Z61), 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 medium-pressure pipelines of thermal power plants and related industrial pipeline systems as an on-off control component.
It is specifically matched to the working conditions of Sasan Ultra Mega Power Plant, mainly used for cutting off or connecting medium-temperature, medium-pressure steam and water media in pipeline systems, with a maximum working temperature of 425℃ (matching WCB carbon steel material performance), and well adapts to the stable operation needs of power plant instrument loops and main pipeline systems, ensuring the safe and smooth operation of the power generation process, in line with the plant's green and efficient operation requirements promoted by YOYIK's technological innovation.
