## Summary description

FERRO KPO4 is a 5/4" ball valve with threaded (female-to-female) connections designed for water installations. The valve provides on/off control of water flow in plumbing systems and is intended for use in residential or commercial piping where a threaded metal shut-off valve is required. Suitable for installation in cold and hot water lines with standard threaded fittings.

## Long description

FERRO KPO4 5/4" threaded water connection is a metal ball valve designed for on/off control of water flow in plumbing systems. The valve features female-to-female threaded ends and a full-port ball mechanism that enables quick shut-off and reliable sealing for both cold and hot water lines. Constructed for standard threaded fittings, it fits residential and light-commercial installations where a compact, durable shut-off valve is required.
Advantages
The FERRO KPO4 ball valve offers straightforward operation and long service life thanks to its robust metal body and ball mechanism. Threaded female-to-female connections simplify inline replacement or integration into existing piping with standard threads. The design minimizes pressure drop when open and provides a tight seal when closed, reducing the risk of leakage. Its compatibility with both cold and hot water applications makes it a versatile choice for a variety of plumbing tasks.
Suitable for
Shut-off and isolation of water lines in residential plumbing
Use in commercial or light-industrial water supply systems
Inline replacement of threaded shut-off valves
Installation on standard hot and cold water pipelines
Key specifications
Connection type: female-to-female threaded ends
Nominal size: 5/4"
Flow control: quarter-turn ball valve (on/off)
Material: metal body with machined ball and sealing components
Application: suitable for hot and cold water lines
How to use
Install the valve inline by threading the female ends onto compatible male-threaded pipe fittings or adapters, ensuring proper thread sealant (e.g., PTFE tape or suitable pipe dope) is applied to the mating threads. Orient the handle so it is accessible for operation; a quarter turn of the handle opens or closes the valve. Verify correct installation by pressurizing the system gradually and checking for leaks around the threaded connections and the valve stem. Perform routine visual inspections and operate the valve periodically to prevent seizing in long-term installations.
Usage recommendations
Use standard thread sealants on mating threads and avoid overtightening to prevent damage to threads or valve body. Ensure the valve is specified for the system temperature and pressure ranges in your installation, and consult relevant plumbing standards for mounting orientation and support of connected piping.
