SHUANGLIN
The DN25 drain valve from SHUANGLIN VALVE is designed for efficient system drainage and safe maintenance in piping networks where controlled discharge of fluid is required. Built with a compact structure and reliable sealing performance, it is widely used in HVAC systems, water distribution lines, industrial piping, and pressure vessel auxiliary systems.
This drain valve features a robust brass body, commonly manufactured from high-quality Hpb59-1 brass, ensuring strong mechanical strength and long service life under frequent operation. The DN25 (1”) size makes it suitable for medium-flow pipelines, offering a balanced solution between compact installation and effective discharge capacity.
A key highlight of this design is its user-friendly operation. The red lever handle allows quick on/off control, enabling operators to open or close the valve within seconds during maintenance or system flushing. The attached safety cap with chain helps prevent contamination or accidental loss, improving long-term usability in field installations.
The SHUANGLIN VALVE DN25 drain valve is engineered to perform under stable industrial conditions:
Size: DN25 (1”)
Material: Hpb59-1 brass body
Thread standard: BSP or NPT optional
Working pressure: ≤ 1.6 MPa
Working temperature: -10°C to 120°C
These specifications make it suitable for both residential and industrial fluid systems, especially where durability and sealing reliability are essential.
With standardized threaded connections, the valve is compatible with a wide range of international piping systems. BSP and NPT options ensure flexibility for different regional installation requirements. Its compact inline structure allows easy integration into tight piping layouts without requiring major system modifications.
The DN25 drain valve is commonly applied in:
HVAC drainage and maintenance lines
Water supply and distribution systems
Pressure vessel and tank bottom discharge
Industrial pipeline flushing systems
Boiler auxiliary drainage connections
In these applications, the valve ensures smooth and controlled fluid release, helping reduce system downtime and improving maintenance efficiency.
As a professional valve manufacturer, SHUANGLIN VALVE focuses on precision casting, stable sealing performance, and long-term durability. Each drain valve undergoes strict quality control to ensure consistent performance under pressure and temperature variations.
By combining practical design with reliable materials, SHUANGLIN VALVE delivers a DN25 drain valve that meets the demands of modern piping systems while maintaining cost-effectiveness and operational safety.
