Union Valve HD742X DN2500 Hydraulic Check Butterfly Valve

Recently, Union Valve successfully completed the production and assembly of the large-diameter HD742X DN2500 hydraulic control check butterfly valve. Designed for large water supply systems, raw water transmission lines, and pump station applications, this valve represents a further expansion of the company’s large-diameter butterfly valve and hydraulic control check valve product range, strengthening its offering for municipal and water conservancy projects.

The HD742X DN2500 hydraulic control check butterfly valve uses a hydraulic control system to regulate the closing movement of the disc, allowing the valve to close smoothly and in a controlled manner during pump shutdown. This helps reduce instantaneous impact on pipelines and equipment, making it well suited for large-diameter pipelines and pump station operating conditions. In addition, the valve can replace the conventional combination of an outlet shut-off valve and a check valve at pump outlets, achieving multiple functions in a single valve and helping simplify pump station piping layouts.

In terms of structural design and operational reliability, the valve is equipped with a clear and intuitive position indicator as well as adjustable mechanical travel stops. The travel control mechanism features a water- and dust-resistant design, giving the valve a robust overall structure that is well suited for long-term continuous operation and helps improve operational reliability and service life.

During manufacturing, Union Valve follows the specific machining and assembly requirements for large-diameter valves, maintaining strict control over machining accuracy and assembly quality for the valve body, disc, and other critical components. Corresponding assembly inspections and functional checks are carried out to ensure stable opening and closing performance and reliable check function prior to delivery.

The completion of the DN2500 hydraulic control check butterfly valve covers the machining and assembly of the ultra-large valve body and disc, as well as full valve integration, placing high demands on equipment capability, machining precision, and assembly conditions. The successful manufacture of this valve demonstrates Union Valve’s complete production and delivery capability for large-diameter butterfly valve assembly, meeting the size and manufacturing requirements of large water supply and pump station projects.
