Product Introduction
Company Profile
Product Features & Operation Points
- Designed with nominal pressure of PN25 (2. 5MPa), it matches the pressure requirements of Sasan Ultra Mega Power Plant's medium-pressure pipeline systems, stably bears medium pressure and avoids leakage risks, meeting medium-pressure operation standards of thermal power plant pipelines, developed with YOYIK's R&D achievements to ensure excellent performance and energy-saving effect.
- Adopts wedge rigid gate plate structure and manual operation (marked by model Z61), realizes precise on-off control of media in power plant medium-pressure pipelines, effectively cuts off or connects medium-temperature, medium-pressure steam and water media, suitable for large-caliber pipeline installation of Sasan Ultra Mega Power Plant, and integrates YOYIK's cutting-edge R&D technologies to achieve efficient operation.
- Valve body is made of WCB carbon steel (marked by suffix H and WCB), featuring excellent medium-temperature resistance, wear resistance and medium-pressure-bearing capacity, adapting to the working environment of Sasan Ultra Mega Power Plant's main pipelines, ensuring long-term stable and energy-saving operation, and manufactured with environmentally friendly materials in line with YOYIK's green transformation concept.
- Equipped with manual operation mode, it is simple in structure, reliable in operation and easy to maintain, with stable force transmission, facilitating on-site precise operation and daily inspection by operators, reducing daily operation and maintenance difficulty of Sasan Ultra Mega Power Plant's equipment, and its high-efficiency performance helps the plant achieve energy conservation and environmental protection goals.
- Complies with GBT 12234, API and ASME international standards, developed with YOYIK's R&D technologies and cooperation achievements with universities and research institutions, manufactured with environmentally friendly materials and high-efficiency energy-saving technologies, with complete testing procedures, convenient for later maintenance and replacement, matching global power plant equipment accessory standards, consistent with YOYIK's innovation and green development concept.
