## Long description

FERRO ZZM5 with a brass closing element and a 6/4" connection is a check valve designed to allow fluid to flow in one direction and to prevent backflow in plumbing and heating systems. The valve uses a metallic (brass) closure component for reliable sealing and enhanced resistance to wear and corrosion. It is intended for use in residential and light commercial installations where a compact, durable non-return device is required.
Advantages
The brass closing element provides improved durability and corrosion resistance compared with non-metallic closures, ensuring long-term tightness and reduced maintenance needs. The 6/4" connection size accommodates common piping configurations in heating and sanitary systems, while the metallic design supports reliable operation under typical system pressures and temperatures. The construction is compact, making installation straightforward in confined or retrofit situations.
Suitable for
 Domestic heating systems (radiators, boilers)
 Sanitary water installations to prevent backflow
 Light commercial plumbing requiring reliable non-return protection
 Retrofit projects where space is limited
Key specifications
 Closing element material: brass
 Connection size: 6/4" (female/male threaded connection as used in plumbing systems)
 Function: check valve / non-return valve for unidirectional flow
 Typical applications: potable water and heating circuits
 Construction: metallic sealing element for wear resistance
How to use
Install the FERRO ZZM5 in the piping with the flow direction matching the arrow or marking on the valve body. Ensure threads and mating surfaces are clean and use appropriate sealing material on threaded joints to prevent leakage. Tighten to recommended torque for the pipe fittings used, avoiding excessive force that could damage threads or the valve body. Verify that system pressure and temperature are within the allowed range for metal check valves and perform a leak test after installation.
Usage recommendations
For reliable performance, avoid exposing the valve to aggressive chemicals not compatible with brass. Periodic visual inspection is recommended to confirm there is no external corrosion or leakage; in heating systems, ensure the valve is accessible for service and not subjected to mechanical strain from piping. When installing in potable water systems, follow local plumbing codes and use approved sealing materials.
