Pumps Reed valves are used in some reciprocating compressor designs, and in the pumping element of some musical instruments, large and small. The physical inertia of reed valves means that they are not as entirely precise in action as rotary valves, a rotary valve engine may run better than a reed valve engine at a small rpm range but the reed valve engine often runs better over a wider rpm range. Modern versions often consist of flexible metal or composite materials (fiberglass or carbon fiber). Contents Applications Traditional Reed valves, normally a leather flap covering a hole, are amongst the earliest form of automatic flow control for liquids and gases. Retrieved 2016-01-16.

Composite materials are preferred in racing engines, especially in kart racing, because the stiffness of the petals can be easily tuned and they are relatively safe in failure.

Nevertheless, current technology favors reed valves almost to the exclusion of rotary valves due to their simplicity and low implementation costs and less rotational mass. For high speed applications (compressors and engines) the dynamic response has to be considered. A simple approach consists in the evaluation of first eigenvalue that is compared with exciting frequency. Для владельцев снегоходов скай или ски ду, как их еще называют, есть отличная новость. Section of Mota-10 reed valves Reed valves are a type of check valve which restrict the flow of fluids to a single direction, opening and closing under changing pressure on each face.
