Ball valve kfa² 700-110-10, female-female 3/8" water

The kfa² 700-110-10 ball valve with female-female 3/8" threaded connections is a compact quarter-turn shut-off valve designed for water installations. Its inline construction and simple threaded ends make it suitable for fast replacement or new connections in domestic plumbing and heating circuits. The valve offers reliable sealing for potable water and central heating applications and is engineered for straightforward manual operation and maintenance.

Advantages

This ball valve delivers tight shut-off with a single quarter-turn action, reducing operating time during installation and servicing. The compact body and female-female 3/8" threads allow space-saving inline connection to small-diameter pipes and fittings. Designed for water systems, the valve provides durable sealing performance and straightforward mechanical operation, minimizing the risk of leaks when installed correctly.

Suitable for

• Domestic potable water lines
• Radiator supply and return connections
• Small-diameter heating circuits and zone valves
• Repair or replacement of existing 3/8" threaded fittings

Key specifications

• Connection type: female–female threaded
• Thread size: 3/8"
• Operation: quarter-turn ball valve (manual)
• Media: water (potable and heating systems)
• Design: compact inline body for small-diameter piping

How to use

Shut off the main supply before replacing or installing the valve. Apply appropriate thread sealant or tape to the male threads of the mating fittings, then hand-start the valve onto each threaded connection and tighten with a suitable wrench without over-torquing. Operate the lever through a 90° turn to open or close the flow; ensure the lever position matches the desired flow direction. After installation, pressurize the line and inspect all joints for leaks; retighten if necessary following manufacturer torque guidance for threaded plumbing fittings.

Usage recommendations

Use the valve only with water in temperature and pressure ranges compatible with typical domestic and heating systems. Avoid excessive torque during installation to prevent damage to threads or valve body. For permanent installations in potable water systems, use approved thread sealants and follow local plumbing codes. Periodically cycle the valve to prevent seizing in seldom-used lines.
