Ball valve kfa² 1" threaded union model 700-220-25, brass connection

Inline ball valve kfa² 1" threaded union model 700-220-25 is a compact brass valve designed for on/off flow control of water and other non-aggressive fluids in residential and commercial plumbing systems. The valve features a full-port ball for low pressure drop and reliable shut-off, and a threaded union connection that simplifies installation and future maintenance. Its brass construction provides corrosion resistance and mechanical strength suitable for supply and distribution pipelines.

Advantages

The full-port ball design ensures minimal flow restriction and efficient operation under typical plumbing pressures. The threaded union connection allows quick assembly and disassembly without rotating entire pipe runs, making service and replacement straightforward. Brass construction combined with precise machining delivers long-term sealing performance and resistance to common water-related corrosion. The valve’s compact body saves space in tight installations and is compatible with standard 1" threaded piping.

Suitable for

• Domestic hot and cold water supply lines
• Commercial plumbing and distribution manifolds
• Maintenance and service sections where easy removal is required
• Systems handling non-aggressive liquids such as treated water and glycol mixtures (as permitted by media compatibility)

Key specifications

• Nominal size: 1"
• Body material: brass
• Connection type: threaded union
• Port type: full-port ball
• Function: on/off flow control
• Typical media: water and non-aggressive fluids

How to use

Install the valve in-line with the flow direction matching system layout and tighten the threaded union connection to the mating pipe fitting using appropriate sealing material or tape as required by local plumbing practice. Operate the lever or actuator to open or close the ball passage; a quarter-turn operation provides rapid switching between open and closed positions. For service, loosen the union nut to remove the valve without disturbing adjacent pipework, then reassemble ensuring proper sealing and alignment.

Usage recommendations

Verify media compatibility and maximum operating pressure and temperature of the valve with system requirements before installation. Avoid using the valve with aggressive chemicals not rated for brass. Periodically cycle the valve and inspect threaded connections for leaks; tighten or re-seal connections during scheduled maintenance to ensure reliable operation.
