The delivered DN2000 and DN2800 motorized large-diameter non-rising stem gate valves are designed, manufactured, and tested in strict accordance with AWWA C509 / AWWA C515, EN 1074-2, ASME B16.34, and ISO 5208 international standards, fully meeting the stringent requirements for tight sealing, high reliability, and long-term stable operation in large-scale water transmission, energy, and municipal pipeline systems.

The valve body is manufactured from ductile iron QT450-10 (equivalent to EN-GJS-450-10), offering excellent structural strength and pressure resistance, making it suitable for municipal water supply systems, wastewater treatment, long-distance water transmission pipelines, power plant circulating water systems, and energy infrastructure pipelines.

With smart manufacturing systems and rigorous quality control, DAQIAN Valves has established a reliable and globally trusted delivery system within the industrial valve supply chain.

Each DAQIAN gate valve undergoes strict pressure testing, sealing testing, and operational performance verification, ensuring high sealing performance, low torque operation, and long service life under large-diameter, low pressure-loss, and continuous operating conditions, consistently meeting and exceeding customer engineering expectations.

We sincerely thank our global customers for their long-term trust and support.

DAQIAN Valves delivers not only products, but also quality, reliability, and long-term value — connecting the world and creating shared prosperity.
