Check valve FERRO ZZM2 with brass closing element 3/4" — plumbing backflow valve

FERRO ZZM2 with brass closing element is a 3/4" check valve designed to prevent backflow in plumbing systems. The valve uses a brass sealing/closing component to provide corrosion-resistant contact with the medium and to ensure reliable sealing under normal operating pressures. Intended for standard 3/4" pipe connections, this non-return valve is suitable for potable water installations and heating circuits in domestic and commercial applications where prevention of reverse flow is required.

Advantages

The brass closing element reduces the risk of corrosion and increases service life in water and heating applications. Its 3/4" size makes it compatible with common plumbing fittings and connections. The valve's straightforward construction offers reliable one-way flow control with minimal maintenance needs. Materials in contact with the fluid are chosen to meet requirements for potable water use and to provide stable performance in heating circuits.

Suitable for

• Domestic water supply systems
• Commercial water installations
• Heating circuits and boiler protection
• Applications requiring backflow prevention for potable water

Key specifications

• Connection size: 3/4" compatible with standard pipe fittings
• Closing element material: brass (corrosion resistant contact parts)
• Type: check valve / non-return valve for one-way flow control
• Installation orientation: inline, for standard plumbing lines
• Intended media: potable water and heating fluids

How to use

Install the FERRO ZZM2 in the pipeline in the flow direction indicated by the valve design. Use appropriate threaded or fitted connections compatible with 3/4" pipe size and ensure sealing with suitable tape or sealant where required. Verify that materials and sealing methods comply with local regulations for potable water systems. After installation, pressurize the system and inspect for leaks and correct one-way operation before returning the installation to service.

Usage recommendations

For reliable long-term operation, periodically inspect the valve and surrounding connections for signs of wear, leakage, or corrosion. In systems with particulate contamination, consider installing a strainer upstream to reduce the risk of debris affecting the closing element. Follow local plumbing codes for installation and maintenance intervals to ensure continued suitability for potable water use.
