## Summary description

ARCO Arco STOP is a mushroom-type check valve with anti-scale (anti-limescale) design, featuring 1" female (1GW) inlet and outlet connections. It prevents backflow in plumbing systems, protects installations from reverse flow and reduces limescale buildup on the closing element. Suitable for residential and light commercial water supply and heating applications.

## Long description

ARCO Arco STOP is a mushroom-type check valve with an anti-scale design and 1" female inlet and outlet connections. It prevents backflow in plumbing and heating systems by allowing fluid to flow in one direction and closing reliably against reverse flow. The valve's anti-limescale feature reduces scale accumulation on the closing element, helping to maintain consistent operation and extend service intervals in residential and light commercial installations.
Advantages
The mushroom-type seat provides a compact, reliable sealing surface that minimizes pressure drop while ensuring tight closure under reverse flow conditions. The anti-scale design slows limescale formation on the moving parts, reducing maintenance needs and preserving valve performance over time. Standard 1" female connections make the valve compatible with common pipe fittings, simplifying installation and replacement in existing systems.
Suitable for
Domestic water supply lines
Heating circuits and boiler return lines
Light commercial plumbing installations
Applications requiring backflow prevention and reduced limescale on valve components
Key specifications
Type: Mushroom-seat check valve
Connection size: 1" female inlet x 1" female outlet
Function: Prevents reverse flow (non-return valve)
Anti-scale feature: Design reduces limescale buildup on closing element
Typical use: Cold and hot water systems, heating circuits
How to use
Install the valve in-line with the flow direction indicated by the valve body markings, orienting the connections to match the system piping. Use appropriate sealing materials on threaded joints and tighten to manufacturer-recommended torque to avoid leaks. The valve operates automatically: forward flow opens the mushroom seat to allow passage, and flow reversal forces the seat closed to prevent backflow. Periodically inspect the valve for signs of leakage or reduced movement, and perform maintenance as required by the overall system schedule.
Usage recommendations
For reliable performance, install the valve in accessible locations to allow inspection and occasional cleaning. Avoid installing the valve where heavy debris or particulate-laden fluids are expected; consider upstream filtration in such systems. Verify compatibility with the system's maximum temperature and pressure ratings before installation and follow local plumbing codes and best practices.
