Check valve with brass strainer ARCO 1 1/4" (model 190806)

Inline check valve with integrated brass strainer by ARCO in 1 1/4" size is a compact hydraulic component designed to ensure unidirectional flow while preventing debris from entering pumps and piping. The unit combines a spring- or gravity-operated non-return mechanism with a removable brass mesh basket that captures particles, protecting system components and reducing maintenance needs. It is suitable for water distribution systems, irrigation circuits and pump intakes where contamination and backflow must be controlled.

Advantages

The integrated brass strainer provides mechanical filtration at the valve inlet, reducing the risk of clogging and abrasion to downstream equipment. Its check valve function prevents reverse flow that can damage pumps or cause pressure loss. Constructed with corrosion-resistant materials where contact with water is expected, the component is compact for easy inline installation and allows access to the strainer basket for cleaning without dismantling large sections of pipework.

Suitable for

• Residential and commercial water supply lines
• Irrigation systems and garden watering setups
• Pump inlets and booster pump installations
• Circuits where sediment or particulate protection is required

Key specifications

• Connection size: 1 1/4" inline
• Integrated removable brass mesh strainer
• Non-return (check) valve mechanism for one-way flow
• Material: brass components in contact with fluid
• Suitable for potable and non-potable water systems (check compatibility with local standards)

How to use

Install the valve in the pipeline following the indicated flow direction marking; ensure correct orientation so the check mechanism operates properly. Fit the valve between compatible threaded or flanged connections using appropriate sealant or tape on threads if applicable. Periodically inspect the strainer basket by removing the access cap or cover, clear accumulated debris, and re-seat the basket before returning the system to service. Observe pressure and temperature limits of the piping system and avoid excessive mechanical stress on the valve body during installation.

Usage recommendations

For reliable operation, schedule regular maintenance checks and cleaning of the brass strainer to prevent buildup of sediment. Use the valve in systems where particle sizes are within the filtration capabilities of a mesh strainer; install additional pre-filtration if the water contains large solids. When connecting to pumps, ensure the valve is positioned to avoid air trapping and follow pump manufacturer guidelines for inlet fittings.
