N25 Lever-Operated Ball Valve
Introduction
A DN25 lever-operated ball valve is a mechanical valve designed for water supply and drainage systems, as well as for compressed air, hot steam, and non-corrosive liquids. With a nominal diameter of 25 mm (1 inch), it is typically installed on branch pipes, main water supply points, or equipment that requires medium flow rates. The lever-operated design allows for quick and easy on/off operation with a simple 90-degree turn.
This valve is manufactured by well-known brands such as MIHA, MBV, Shin Yi, Tunglung, Wonil, and Kitz, making it suitable for residential projects, workshops, technical stations, and light industrial systems.
