Rinse aid check valve Stalgast C012109

A check valve controls the flow of rinse aid liquid in commercial dishwashers, allowing it to move in one direction only. This prevents backflow, which could contaminate the rinse aid reservoir or disrupt the dosing system. The valve operates mechanically, using pressure from the liquid to open and gravity or a spring to close, ensuring that the correct amount of rinse aid is released during each rinse cycle without manual intervention.

In use, the valve is installed inline within the rinse aid feed line. When the dishwasher's rinse cycle begins, water pressure pushes the rinse aid liquid through the valve, which opens to allow passage. Once the cycle ends and pressure drops, the valve seals shut, stopping any reverse flow. This maintains the integrity of the rinse aid supply and ensures consistent performance across multiple wash cycles.

The construction of this check valve is designed for compatibility with standard rinse aid dosing systems. It fits into the liquid feed line without requiring additional adapters or modifications, making it a direct replacement for worn or faulty valves in existing equipment.

Cleaning and maintenance are minimal, as the valve has no moving parts exposed to food or debris. Periodic inspection of the feed line for blockages or wear ensures reliable operation, while replacement is straightforward if the valve no longer seals properly.

This Stalgast check valve is a spare part for professional dishwashers where rinse aid liquid dosing is part of the automated wash programme.
