Check valve kfa² 2" with brass disc model 710-010-50

The kfa² check valve 2" (model 710-010-50) with a brass disc is designed to prevent backflow in water and heating pipeline systems. The valve is intended for inline installation in straight pipe runs and provides one-way flow control to protect pumps, boilers and other system components from reverse flow. The brass disc provides corrosion resistance appropriate for standard residential and commercial installations and supports reliable operation under normal pressure and temperature ranges common to water and heating systems.

Advantages

The brass disc construction offers enhanced corrosion resistance compared with some non-metallic alternatives, improving durability and reducing maintenance frequency. The valve’s design ensures a compact inline profile suitable for tight installation spaces and straightforward integration with standard 2" piping. Its one-way mechanism operates automatically without external power or controls and helps maintain system efficiency by preventing unwanted reverse flow.

Suitable for

• Domestic and commercial water supply lines
• Heating systems including central heating circuits and boiler protection
• Pump discharge lines to prevent backflow when pumps stop
• Straight pipe runs where non-return flow control is required

Key specifications

• Connection size: 2 inches nominal
• Internal component material: brass disc
• Intended medium: water for supply and heating systems
• Mounting orientation: inline, for straight runs with flow direction control
• Operation: automatic one-way (non-return) valve

How to use

Install the check valve in the pipeline with the flow arrow aligned with the intended fluid direction. Ensure pipe ends and fittings are clean and free of debris before making connections, and use compatible sealing materials appropriate for the chosen joining method (threaded, soldered or flanged as applicable). After installation, pressurize the system gradually and inspect joints for leaks. Verify correct operation by observing unimpeded forward flow and by confirming there is no reverse flow when the supply is stopped.

Usage recommendations

Choose the kfa² check valve 2" with brass disc for standard water and heating applications where corrosion resistance and a compact inline non-return solution are required. Periodic visual inspection and occasional functional checks during routine system maintenance are recommended to ensure continued reliability. If the system operates outside typical domestic or commercial temperature and pressure ranges, confirm compatibility with a qualified technician.
