## Summary description

Flap-type check valve ARCO model 190203 with 1/2" (DN15) connection. Designed to prevent backflow in liquid piping systems, this compact non-return valve uses a pivoting flap to allow unidirectional flow. Suitable for domestic and light industrial applications in water supply, heating circuits and pump discharge lines where a DN15 size is required.

## Long description

Flap-type check valve ARCO 1/2" DN15 (model 190203) is a compact non-return valve designed for preventing backflow in liquid piping systems. The valve uses a pivoting flap that opens under forward flow and closes reliably when flow reverses, ensuring unidirectional fluid movement. Its DN15 (1/2") connection makes it suitable for small-diameter water supply, heating circuits and pump discharge lines in domestic and light industrial installations.
Advantages
The ARCO flap valve offers a straightforward mechanical design that provides reliable backflow prevention with low pressure loss in the forward direction. Its compact size and standard 1/2" connection allow easy integration into existing pipework. The pivoting flap responds quickly to changes in flow, reducing water hammer and reverse-flow risks when installed correctly.
Suitable for
Domestic water supply lines with DN15 piping
Heating system circuits and radiators
Pump discharge lines to prevent reverse flow
Small commercial or light industrial liquid systems requiring a compact non-return valve
Key specifications
Valve type: flap / swing check valve
Connection size: DN15 (1/2")
Flow direction: unidirectional with pivoting flap
Typical applications: water supply, heating circuits, pump discharge
Construction: compact design for inline installation
How to use
Install the ARCO flap valve in the piping with the arrow or flow-marking aligned to the intended flow direction. Ensure pipework is supported and free of debris before fitting to avoid obstruction of the pivoting flap. Connection should be made with compatible 1/2" fittings or adapters and tightened to the manufacturer’s recommended torque values for the chosen joint type. After installation, pressurize the line and check for leaks and proper flap operation by observing flow in the forward and reverse directions.
Usage recommendations
Use this valve in clean liquid systems; avoid installing in media with high particulate content without appropriate filtration. Regular inspection and occasional cleaning of the valve area are recommended to maintain reliable operation. For installations in heating systems, verify compatibility with system temperature and pressure and follow local plumbing codes.
