## Long description

FERRO KM31 1" ball valve with threaded (nakrętno-wkrętny) connection is a compact quarter-turn shutoff valve engineered for plumbing and heating systems. The valve provides straightforward on/off control via a rotating ball mechanism and is suitable for installation in standard threaded pipe fittings. Its compact form and simple operation make it appropriate for both residential and light commercial applications where a reliable serviceable shutoff is required.
Advantages
The valve offers a robust quarter-turn ball mechanism that ensures quick and positive flow shutoff. Its threaded connection type simplifies installation and replacement in existing piping. The compact design reduces space requirements and allows fitting in confined service cabinets or manifolds. Constructed from corrosion-resistant materials, it provides long-term operation with minimal maintenance under normal plumbing and heating conditions.
Suitable for
Domestic water supply shutoff points
Heating system branch isolation and maintenance
Connection to threaded pipe fittings in boilers, radiators, and manifolds
Light commercial plumbing where durable shutoff valves are needed
Key specifications
Connection type: threaded (nakrętno-wkrętny) 1"
Operation: quarter-turn ball valve
Application: plumbing and heating system shutoff
Design: compact inline body suitable for confined spaces
Typical media: potable water, heating circuit fluids (as per system requirements)
How to use
Install the valve in a matching threaded pipe run, ensuring thread sealing with appropriate tape or sealant compatible with potable water and heating systems. Align the valve so the handle can be turned freely; a 90° rotation opens or closes the flow. For routine operation, turn the handle smoothly to avoid sudden pressure surges. When performing maintenance or replacing components downstream, close the valve fully to isolate the section of pipework.
Usage recommendations
Verify system compatibility before installation, including maximum pressure and temperature limits of the heating or plumbing circuit. Use compatible thread sealants and avoid excessive tightening that could damage threads. Periodically operate the valve to prevent seizing and inspect for leaks or corrosion during scheduled maintenance.
