Ball draw-off valve kfa² 3/4" model 704-010-20 for water installations

The Ball draw-off valve kfa² 3/4" model 704-010-20 for water installations is a quarter-turn ball valve with a 3/4" threaded connection intended for isolating and controlling water flow in supply systems. Designed for use in domestic and light commercial plumbing, the valve provides a simple shut-off solution for fixtures, appliances and maintenance points where a reliable closed/open action is required. The construction combines a conventional ball mechanism with a compact body suitable for inline installation in copper, brass or plastic piping arrangements.

Advantages

This kfa² ball draw-off valve delivers a fast quarter-turn operation for quick shut-off and minimal flow resistance when fully open. The ball mechanism ensures tight sealing and reliable isolation for routine maintenance and repairs. Its standard 3/4" connection makes it compatible with common plumbing fittings, while the compact form factor facilitates installation in confined spaces. Materials and design focus on corrosion resistance and consistent performance in water supply applications.

Suitable for

• Isolating sinks, toilets and other sanitary fixtures
• Connecting water-using appliances such as washing machines and dishwashers
• Temporary shut-off during plumbing maintenance or repair
• Use in domestic and small commercial water distribution lines

Key specifications

• Type: Quarter-turn ball valve (draw-off valve)
• Connection size: 3/4" threaded
• Operation: Manual lever, quarter-turn
• Medium: Cold and hot potable water
• Application: Inline installation for isolation and flow control
• Body: Compact design suitable for confined installation spaces

How to use

Install the valve in the water line using appropriate threaded fittings and sealing tape or joint compound to ensure leak-free connections. Operate the valve using the lever: a 90° turn closes or opens the ball bore. Before installing, depressurize the system and drain the section of pipe where the valve will be fitted. After installation, check for leaks at threaded joints and operate the valve to confirm smooth rotation and full shut-off.

Usage recommendations

For reliable long-term performance, avoid overtightening threaded connections and ensure that the valve is compatible with the system’s water temperature and pressure. Periodically cycle the valve to prevent sticking and inspect for signs of corrosion or wear. Use appropriate sealing materials on threads and follow local plumbing codes when integrating the valve into potable water systems.
