## Long description

FERRO KP4 is a 5/4" ball valve with a screw-handle and threaded female/male connection designed for reliable flow control in plumbing and heating systems. The valve provides straightforward on/off operation with a full-bore ball element that ensures a tight shut-off and minimal pressure drop when open. Constructed for residential and light commercial installations, this threaded ball valve suits water, heating circuits and general fluid line applications where a durable, easy-to-operate shut-off is required.
Advantages
The screw-style handle offers secure manual operation and prevents accidental movement, while the threaded connection enables simple installation into existing pipework without welding. The ball valve design gives quick switching between open and closed positions and a compact profile that fits within confined spaces. Materials and construction provide corrosion resistance appropriate for typical potable water and heating system conditions, ensuring long-term functionality with routine maintenance.

How to use
Install the valve in a pipeline with compatible threaded fittings, ensuring correct thread orientation for the female and male ends. Tighten using appropriate tools without over-torquing to avoid damaging threads or the valve body. Operate the screw-handle to move the ball between open and closed positions; the valve is designed for simple quarter-turn actuation. Before installation, flush the pipeline to remove debris that could affect sealing. Perform a pressure test after fitting to verify leak-free joints.
Usage recommendations
Use the FERRO KP4 ball valve within the manufacturer’s recommended temperature and pressure limits for typical water and heating systems. Avoid using the valve with aggressive chemicals or abrasive media. For long service life, cycle the valve periodically in systems subject to long idle periods and inspect seals during routine maintenance intervals.
