Product information

Description

Ball valve INVENA MILLENIUM with butterfly handle, internal/external thread 1/2" - ZK-31-015 is a compact quarter-turn shut-off valve designed for use in residential and commercial plumbing systems. The valve features a butterfly (wing) handle for manual operation and combined internal/external 1/2" threaded connections that allow installation between threaded pipe sections or fittings. It is intended for flow shut-off and basic flow control in water supply lines, heating circuits and general piping where a small, easy-to-operate threaded ball valve is required.

Advantages

The valve's quarter-turn ball design provides quick and clear on/off operation while the butterfly handle enables easy manual control in confined spaces. Combined internal and external 1/2" threads increase installation flexibility, permitting connection to different threaded fittings without additional adapters. The compact form factor makes it suitable for tight installation areas and standard household piping.

Suitable for

  • Domestic cold and hot water supply lines
  • Heating circuit branches and radiator shut-off
  • General threaded piping installations in apartments and small commercial premises

Key specifications

  • Valve type: ball valve with quarter-turn operation
  • Handle type: butterfly (wing) handle for manual operation
  • Connection: combined internal and external 1/2" threaded ends
  • Application: flow shut-off and basic flow control in water and heating systems
  • Design: compact form factor for installations in limited spaces

How to use

Install the valve in the pipeline using the 1/2" threaded ends, ensuring proper sealing with appropriate thread sealant or tape as required by the system. Operate the valve by turning the butterfly handle approximately 90 degrees: perpendicular to the pipe axis for closed position and parallel for open position. Before installation or maintenance, depressurize and drain the section of the system where the valve will be fitted. Perform visual inspection after installation to confirm there are no leaks at the threaded joints.

Usage recommendations

Use the valve for on/off control and occasional throttling only; it is not intended for fine flow regulation. Avoid using excessive force on the butterfly handle to prevent damage to the operating mechanism. Periodically check threaded connections for tightness and inspect for signs of leakage; if used in heating systems, follow system-specific maintenance intervals and water quality recommendations to prevent premature wear.
