kfa² ball valve with angled filter 1" model 708-010-25

kfaball valve with angled filter 1" model 708-010-25 is a compact combination fitting that integrates a quarter-turn shut-off ball valve with an angled (oblique) strainer designed to retain debris and protect downstream plumbing equipment. The unit is intended for inline installation in potable water and heating circuits where a simple, space-saving solution is required to both stop flow and capture particulates before pumps, meters or fixtures.

Advantages

The combined design saves installation space by uniting shut-off and filtration functions in one body, simplifying piping layouts and reducing the need for separate components. The angled filter basket allows for effective debris retention while maintaining a smooth flow path, and the ball valve provides a reliable, fast-acting shut-off. Constructed for typical residential and light-commercial water systems, the fitting offers straightforward maintenance via an accessible strainer chamber and minimal pressure drop when the strainer is clean.

Suitable for

• Protection of pumps, water meters and heat exchangers from sediments and particles
• Inline shut-off and filtration in potable water supply lines
• Heating system branches and return lines where compact fittings are required
• Renovation projects to replace separate valve and strainer assemblies with a single compact unit

Key specifications

• Nominal size: 1" (inch)
• Function: quarter-turn ball valve with integrated angled strainer
• Connection type: inline threaded connections suitable for standard 1" piping
• Flow orientation: angled/oblique strainer chamber directing debris away from the main flow path
• Material considerations: metal valve body with removable filter insert for maintenance
• Typical applications: potable water, heating circuits, light-commercial water installations

How to use

Install the fitting in the pipeline following flow direction indications, ensuring threaded connections are sealed according to local plumbing practice. Use the ball handle to open or close flow with a 90 turn. Periodically isolate the valve and open the strainer chamber to inspect and clean the filter insert; debris can be removed and the insert reinstalled without replacing the entire unit. Observe system pressure and temperature limits defined by the overall installation standards.

Usage recommendations

For reliable operation, flush the pipeline before installation to remove loose particles, perform routine inspection of the strainer at scheduled maintenance intervals, and avoid using harsh solvents or abrasive tools when cleaning the filter insert. Ensure compatibility with system media and temperatures typical for residential and light-commercial water systems.
