Brass Check Valve with Flapper 2" Perfexim 04-020-0500-000

The Perfexim Brass Check Valve with Flapper 2" is a non-return valve designed to allow one-way flow and prevent backflow in piping systems. Constructed from brass, the valve offers corrosion resistance and mechanical durability suitable for water and other non-aggressive fluids. Its 2" nominal size and flapper mechanism provide reliable operation in plumbing, heating and irrigation applications where consistent check-valve performance is required.

Advantages

Brass construction provides good resistance to corrosion and wear while maintaining structural strength for long-term operation. The flapper design permits a quick response to flow changes and ensures tight closure under reverse-flow conditions. The valve’s simple mechanical design reduces maintenance needs and makes it straightforward to install in horizontal or vertical runs as per system requirements.

Suitable for

• Domestic and commercial plumbing systems to prevent backflow
• Heating and boiler circuits where one-way flow control is required
• Irrigation and water distribution networks
• Industrial installations handling non-aggressive liquids

Key specifications

• Nominal size: 2"
• Body material: brass
• Closure type: flapper (swing check)
• Application fluids: water and non-aggressive liquids
• Mounting: inline installation in pipeline

How to use

Install the check valve in the pipeline following the flow direction indicated on the valve body. Ensure pipe ends and threads are clean and free from debris before assembly; use appropriate sealing material compatible with brass and the system fluid. Support adjacent pipework to avoid stress on the valve body. After installation, test the system at working pressure to confirm correct orientation and leak-free operation. Periodically inspect the valve for external signs of wear, leakage or blocking debris that could impede flapper movement.

Usage recommendations

Use in systems handling potable water only if compatible with local regulations and materials; avoid aggressive chemicals or fluids that can corrode brass. For installations with frequent pressure surges or water hammer, consider additional protection such as surge arrestors or air chambers to extend valve life. Follow system-specific maintenance schedules and consult technical documentation for torque and connection details.
