## Long description

FERRO ZZM1 is a 1/2" check valve with a brass closing element designed for water installations. The valve allows fluid to flow in one direction while preventing backflow, helping to protect pumps, boilers and piping from reverse flow. Its brass closing component offers corrosion resistance and a reliable seal suitable for potable water and common heating system conditions.
Advantages
The compact 1/2" design fits standard domestic and light commercial plumbing connections and provides straightforward inline installation. The brass closing element increases durability and corrosion resistance compared with standard non-metallic closers, maintaining sealing performance over time. The valve's simple mechanical construction reduces maintenance needs and supports reliable operation under typical water system pressures.
Suitable for
Domestic water supply lines
Boiler and heating circulation loops

Light commercial plumbing installations
Key specifications
Connection size: 1/2" compatible with standard pipe fittings
Closing element material: brass for corrosion resistance
Function: one-way check valve to prevent reverse flow
Typical applications: potable water and heating systems
Construction: inline body suitable for standard installation positions
How to use
Install the check valve in the intended pipeline with the flow direction aligned to the marked direction on the body. Ensure threaded or fitted connections are properly sealed using appropriate sealing tape or compound suitable for potable water. After installation, pressurize the system and check for leaks at the connections and around the valve body. Regularly inspect the valve for signs of leakage or wear during routine system maintenance and replace if sealing performance deteriorates.
Usage recommendations
Use the valve within the pressure and temperature limits of the installation and avoid exposure to aggressive chemicals that could affect brass components. For potable water systems, follow local plumbing codes and use potable-water-approved sealing materials. If installed in a pump discharge line, include accessible shut-off valves and serviceable unions to simplify future inspection or replacement.
