Ball valve kfa² 700-221-15 threaded 1/2" (nakrętno-wkrętny)

Ball valve kfa² 700-221-15 threaded 1/2" (nakrętno-wkrętny) is a compact quarter-turn shut-off valve designed for controlling fluid flow in plumbing and heating systems. The valve uses a ball mechanism operated by a 90° turn to provide a positive open or closed position. Threaded 1/2" connections make it suitable for straightforward integration into existing piping with compatible female threads. The construction and form factor are intended for residential and light commercial installations requiring reliable isolation of water or other compatible fluids.

Advantages

This threaded ball valve offers quick quarter-turn operation for fast shut-off and straightforward control. Its compact size and threaded fittings simplify installation in confined spaces and in retrofit scenarios. The ball design ensures low flow resistance when open and a secure seal when closed, reducing leakage risk. Materials and thread configuration are chosen to provide practical durability and compatibility with standard 1/2" plumbing connections.

Suitable for

• Domestic hot and cold water supply lines
• Heating circuits in residential buildings
• Valving individual appliances or fixtures (e.g., sinks, boilers)
• Light commercial plumbing where a compact shut-off valve is needed

Key specifications

• Connection type: threaded 1/2" (nakrętno-wkrętny)
• Operation: quarter-turn ball valve
• Function: on/off shut-off
• Design: compact inline body suitable for confined installation spaces
• Intended media: water and compatible non-corrosive fluids

How to use

Install the valve into a pipeline with matching 1/2" female threads, using appropriate thread sealant or tape according to installation standards. Ensure the valve is oriented for accessible handle operation and tightened to recommended torque for threaded connections. Turn the handle 90° to move between fully open and fully closed positions; intermediate positions are not intended for long-term throttling. Inspect connections after installation for leaks and verify correct operation before regular use.

Usage recommendations

For reliable long-term performance, avoid using the valve with highly abrasive or corrosive media not specified for standard plumbing ball valves. Periodically operate the valve to prevent seizing and inspect seals and threads during routine maintenance. When used in heating systems, ensure compatibility with system temperatures and follow local plumbing codes for installation and safety.
