Ball valve Detal-met ZK25, polypropylene (PP), 25 mm

Detal-met ZK25 is a 25 mm ball valve manufactured from polypropylene (PP) designed for controlling fluid flow in piping systems. The valve uses a quarter-turn ball mechanism to provide straightforward on/off operation and is produced from corrosion-resistant plastic for applications where metal valves are unsuitable. Its compact design and simple operation make it appropriate for installations where reliable isolation of water or other compatible fluids is required.

Advantages

The polypropylene construction offers chemical and corrosion resistance while keeping the component lightweight. The quarter-turn ball mechanism ensures fast, reliable shutoff and minimal pressure drop in the open position. The valve's smooth internal surfaces reduce sediment accumulation and require little maintenance. Its design is compatible with standard 25 mm plastic piping and fittings commonly used in water supply and irrigation systems.

Suitable for

• Domestic and commercial water supply lines
• Irrigation and garden watering systems
• General plumbing where chemical resistance and lightweight valves are needed
• Temporary or permanent installations in non-corrosive fluid systems

Key specifications

• Material: polypropylene (PP)
• Connection size: 25 mm
• Operation: quarter-turn ball valve for on/off control
• Flow characteristic: full bore with low pressure loss when open
• Corrosion resistance: suitable for water and many common non-aggressive fluids
• Maintenance: low; smooth internal surfaces reduce fouling

How to use

Install the Detal-met ZK25 ball valve inline with compatible 25 mm piping using appropriate solvent welding, fusion, or mechanical fittings as recommended for polypropylene systems. Ensure the flow direction corresponds to any markings if present, and secure connections to prevent leaks. Operate the valve by rotating the handle 90 degrees: parallel to the pipe for open, perpendicular for closed. Periodically inspect seals and connections and perform routine checks to confirm leak-tight performance.

Usage recommendations

Do not use the valve with fluids or temperatures outside the limits of polypropylene; avoid exposure to aggressive solvents or high-temperature systems. For pressurized installations, verify system pressure ratings and use support or anchoring for long pipe runs. When combining with different materials, confirm compatible joining methods and expansion allowances to maintain a reliable seal.
