## Summary description

FERRO KP9 is a 4" ball valve designed for water installations with threaded nut-to-nut connections. It provides on/off flow control via a rotary ball mechanism and is intended for use in plumbing, heating and industrial water systems. Suitable for pipeline shut-off tasks where a threaded 4-inch connection and reliable sealing are required.

## Long description

FERRO KP9 is a 4" ball valve with threaded nut-to-nut connections designed for water installations. The valve uses a rotary ball mechanism to provide reliable on/off flow control and tight shut-off in plumbing, heating and industrial water systems. Its threaded 4" connectors make it compatible with standard pipe fittings where a nut-to-nut configuration is required, and the construction is focused on straightforward installation and maintenance in pipeline shut-off applications.
Advantages
The ball mechanism ensures quick quarter-turn operation for fast opening and closing with minimal pressure drop when fully open. Threaded nut-to-nut connections allow secure mechanical assembly without flanges or welding, while the robust body design provides reliable sealing under typical water system pressures. The valve is suitable for repeated operation, offers straightforward maintenance access, and is designed to integrate into existing piping layouts that use threaded 4" fittings.
Suitable for
 Plumbing systems requiring a 4" threaded shut-off valve
 Heating and hot-water circulation lines with threaded connections
 Industrial water distribution and process lines
 Pipeline sections where quick quarter-turn isolation is needed
Key specifications
 Connection type: threaded nut-to-nut 4"
 Operation: rotary ball, quarter-turn on/off
 Media: water (potable, heating, industrial water systems)
 Application: shut-off/isolation in pipelines
 Installation: inline, between threaded fittings
How to use
Install the valve inline using appropriate 4" threaded fittings and tighten the nuts to the recommended torque for the system to ensure a leak-free connection. Operate the valve by turning the handle a quarter turn to open or close the flow; verify correct orientation during installation so the handle position corresponds to flow state. Follow normal commissioning procedures for water systems, including pressure testing and inspection of joints after installation.
Usage recommendations
Use compatible thread sealants or gaskets as specified for the system pressure and media type. Avoid excessive torque during installation to prevent thread or seal damage. For long-term reliability, perform periodic visual inspections and operate the valve occasionally to prevent seizing in infrequently used lines.
