## Long description

FERRO KM21 3/4" ball valve is a compact shut-off device designed for controlling fluid flow in residential and light commercial plumbing installations. The valve combines a threaded nut connection with a screw-in body for straightforward mounting in distribution and service circuits. Constructed for isolation of water and other non-aggressive media, the KM21 provides reliable performance where space is limited and a simple manual on/off control is required.
Advantages
The KM21 offers a compact design that facilitates installation in tight spaces and minimizes required clearances around piping. Its threaded-press style connection enables secure mechanical joining and simple replacement or maintenance. The ball mechanism provides a tight shut-off with low torque operation, reducing wear on the actuator and ensuring long service life under normal operating conditions.
Suitable for
Domestic hot and cold water distribution
Service circuits and branch lines in residential buildings
Light commercial plumbing where non-aggressive media are used
Applications requiring compact shut-off valves with threaded connections
Key specifications
Connection type: threaded nut and screw-in body compatible with 3/4" pipelines
Valve type: ball valve with manual actuator
Size: 3/4" nominal diameter
Design: compact body suitable for distribution and service circuits
Media: water and non-aggressive fluids
Operation: manual on/off control with low torque
How to use
Install the KM21 valve into the pipeline by screwing the body into the prepared fitting and securing the threaded nut according to standard plumbing practices. Ensure pipe threads and sealing surfaces are clean and properly sealed with appropriate thread sealant or tape for water installations. Operate the valve by turning the handle to the open or closed position; avoid excessive force when operating to prevent damage to the actuator. Before commissioning, perform a leak test at working pressure and check for correct orientation and accessibility for future maintenance.
Usage recommendations
Use the valve only with compatible, non-aggressive media and within recommended temperature and pressure limits for its materials. Regular visual inspection and periodic operation are recommended to prevent seizure and to confirm leak-free performance. If used in systems with particulates or aggressive chemicals, install appropriate filtration or select a valve constructed from materials certified for those media.
