Non-return valve Stalgast C012787

A check valve maintains one-way flow in fluid lines, stopping backflow that could contaminate supplies or disrupt equipment. Inside the valve, a spring-loaded disc or ball rests against a seat. When fluid moves forward under pressure, the disc lifts, allowing passage. As soon as flow stops or reverses, the spring forces the disc back onto the seat, sealing the line. This automatic action requires no operator input and works continuously while the system runs.

In catering setups, the valve is installed inline between pumps, dispensers or holding tanks. The operator connects the inlet and outlet ports to the existing piping, ensuring the arrow on the valve body points in the intended flow direction. Once fitted, the valve operates without adjustment, responding instantly to pressure changes. There are no controls to set; the valve functions purely on fluid dynamics.

The construction uses materials suited to food-safe fluids, though the specific metals or polymers are not detailed. Cleaning follows the same routine as the rest of the fluid line: flushing with approved sanitising solutions to remove residue without disassembly. The valve's simple mechanism has no moving parts exposed to the product stream, reducing maintenance needs.

This check valve fits Stalgast equipment designed for compatible fluid handling, ensuring seamless integration in existing setups. It appears in the catalogue under fluid control components for professional catering systems.
