## Long description

FERRO KM3 is a 1" female-to-female ball valve engineered for water installations. The valve delivers reliable on/off control with a quarter-turn operation and is designed for inline connection where a 1" threaded female coupling is required.

Advantages
The FERRO KM3 ball valve offers simple and fast operation via a 90° turn, enabling quick shut-off and flow restoration. The female-to-female threaded ends allow easy integration into existing pipe runs without additional adapters when mating threaded fittings are used.

Key specifications
 Connection type: 1" female threaded on both ends
 Operation: quarter-turn ball valve (90°)
 Media: potable water and heating water
 Function: manual on/off isolation
 Design: compact inline body for limited-space installations
How to use
Install the FERRO KM3 ball valve inline between matching 1" male threaded fittings or pipes. Ensure thread sealing with an appropriate tape or sealant compatible with potable water systems before tightening. Operate the valve by turning the handle 90° to open or close the flow; position of the handle indicates open (aligned with flow) or closed (perpendicular to flow). For system maintenance, fully close the valve to isolate downstream equipment, then relieve any residual pressure before disassembly.
Usage recommendations
Before installation, confirm compatibility with the installation’s water quality and local plumbing standards. Tighten connections to avoid overtightening that could damage threads. For long-term reliability, periodically cycle the valve and inspect for leaks; replace if seats or seals show deterioration. Use pipe sealants approved for potable water when installed in drinking water systems.
