Brass Check Valve with Poppet 5/2" Perfexim 04-020-0650-000

Perfexim brass check valve with poppet, nominal connection size 5/2" is a compact non-return valve designed to allow flow in one direction and prevent backflow in plumbing and light hydraulic systems. The valve features a poppet sealing element housed in a brass body, providing resistance to corrosion and consistent sealing performance for residential and light-commercial installations where space and reliability are important.

Advantages

The brass construction offers good durability and corrosion resistance in typical water and low-pressure hydraulic environments. The poppet design ensures rapid and positive sealing under backflow conditions, reducing the risk of leakage. Its compact dimensions and standard 5/2" connection make installation straightforward in existing piping layouts. The valve requires minimal maintenance and provides stable operation over repeated cycles.

Suitable for

• Domestic water supply lines and heating systems
• Light-commercial plumbing installations
• Applications requiring prevention of backflow into source lines
• Compact or confined piping runs where a small non-return valve is needed

Key specifications

• Body material: brass for corrosion resistance
• Sealing element: poppet-type for positive shut-off
• Connection nominal size: 5/2" compatible with standard fittings
• Function: unidirectional flow / check (non-return) valve
• Typical installation: inline between pipe sections

How to use

Install the valve in the pipeline ensuring the flow direction marking matches the intended flow. Use appropriate fittings or adapters for the 5/2" nominal connections and tighten following plumbing best practices to avoid over-torquing the brass body. After installation, perform a pressure test at working pressure to verify there is no leakage and that the poppet closes reliably under backflow conditions. Regular visual inspections are recommended to check for external corrosion or mechanical damage.

Usage recommendations

Use the valve within the pressure and temperature ranges suitable for brass components and the poppet sealing material. Avoid exposure to aggressive chemicals or abrasive particulate-containing fluids that could impair sealing performance. For systems with higher pressures, velocities, or aggressive media, select a valve specified for those conditions and consult technical documentation or a professional installer.
