## Summary description

Perfexim brass swing (disc) check valve, nominal 3" size, model 04-020-0800-000. Designed to prevent backflow in pipelines, this threaded/wafer-style check valve uses a hinged disc to allow flow in one direction and close under reverse flow. Suitable for water and neutral fluids in plumbing and heating systems, pump installations, and industrial piping where corrosion-resistant brass components are required.

## Long description

Perfexim brass swing check valve with disc 3" is a threaded/wafer-style valve designed to prevent reverse flow in pipelines. The valve uses a hinged disc that opens with forward flow and closes automatically when flow reverses, providing reliable backflow protection. Constructed from corrosion-resistant brass, it is intended for use with water and neutral fluids in plumbing, heating systems, pump installations and industrial piping where a compact, durable check valve is required.
Advantages
The brass construction provides good corrosion resistance and durability in typical water and neutral fluid applications. The swing disc design ensures low pressure loss during forward flow and a tight closure under reverse flow to reduce water hammer and protect pumps and equipment. Threaded/wafer format allows straightforward installation between flanges or in-line threaded connections and keeps the valve compact and space-saving. The simple mechanical design supports long service life with minimal maintenance when installed correctly.
Suitable for
Domestic and commercial plumbing systems
Heating and radiator circuits
Pump discharge lines to prevent backflow
Industrial piping with neutral fluids
Key specifications
Valve type: swing (disc) check valve
Nominal size: 3 inch
Material: brass body and internal components suitable for neutral fluids
Connection style: threaded / wafer-compatible for inline or between-flange installation
Fluid compatibility: water and neutral fluids
Operation: gravity/flow-actuated hinged disc for one-way flow control
How to use
Install the valve in the pipeline with the flow direction marking aligned with the intended flow. Ensure compatible thread types or wafer spacing and use appropriate seals or gaskets to achieve a leak-free connection. The valve should be mounted horizontally or vertically according to manufacturer guidance and system requirements so the disc can operate freely. After installation, perform a pressure test to confirm correct sealing and check for any leaks. Routine inspections should include visual checks and functional testing to ensure the disc closes on reverse flow.
Usage recommendations
Use in systems carrying potable water or neutral fluids within the valve's pressure and temperature limits; avoid aggressive chemicals or highly abrasive media. When installed on pump discharge lines, consider a short straight run upstream and downstream to minimize flow disturbances. Periodically inspect for signs of corrosion, debris, or wear and replace the valve if sealing performance degrades.
