## Summary description

ARCO 191206 is a mushroom-type check valve with anti-scale design, sized 1 1/4" female thread to 1 1/4" female thread. It prevents backflow in plumbing systems and reduces scale buildup thanks to its construction. Suitable for installation in water supply and heating lines where reliable one-way flow and protection against deposits are required.

## Long description

ARCO 191206 mushroom-type anti-scale check valve with 1 1/4" female threaded connections is designed to allow one-way flow while reducing scale formation. The valve's mushroom internal mechanism provides reliable sealing against backflow in water supply and heating systems. Its anti-scale features and threaded female ends make it suitable for inline installation where prevention of deposits and consistent directional flow are required.
Advantages
The mushroom-type design offers stable sealing under variable flow conditions and limits the accumulation of mineral deposits on critical sealing surfaces. Female threaded connections simplify installation into existing pipelines without special adapters, and the compact body fits standard piping runs. Materials and geometry are selected to provide long-term operation with minimal maintenance in potable water and heating applications.
Suitable for
Domestic and commercial water supply lines
Heating system circulation loops
Return lines where backflow prevention is needed
Installations requiring reduced scale buildup in valves
Key specifications
Connection type: 1 1/4" female threaded inlet and outlet
Valve type: mushroom-style check valve
Function: one-way flow / backflow prevention
Design feature: anti-scale construction to reduce deposits
Typical application medium: potable water and heating fluids
Installation orientation: inline, compatible with horizontal or vertical piping depending on system design
How to use
Install the check valve in the intended section of the pipeline with the flow direction aligned to the valve marking. Threaded female ends require a matching male-threaded pipe or fitting; apply appropriate thread sealant or tape to ensure a leak-free joint. Tighten connections with suitable tools without over-torquing to avoid damaging threads or valve body. After installation, pressurize the system slowly and inspect for leaks, then cycle the system to confirm unobstructed one-way flow and proper sealing against backflow.
Usage recommendations
For longer service life, avoid installing the valve in lines with excessive particulate load; install upstream strainers if necessary. Periodic inspection during routine system maintenance is recommended to verify sealing surfaces remain free of heavy scale. Use compatible thread sealants for potable water systems and follow local plumbing codes for installation and maintenance.
