Quick exhaust valves, check valves and Shuttle valves.
Quick exhaust valves (QEA) increase cylinder rod speed by dumping exhaust air directly at the cylinder instead of back through the control valve. Use one QEA in each cylinder port to increase rod speed in both directions. Using a quick exhaust valve to increase cycling speed allows a smaller, less expensive control valve to be used
Check valve allows the flow of air in and prevents it from going out. They are often simply just called one-way air valves. The most common application is for an air compressor. They allow the compressor to keep certain parts pressurized and other parts de-pressurized.
Shuttle valves are designed to direct flow of fluid from two sources. A simple sealing element is designed and installed to move freely within the shuttle valve. When pressurized fluid enters the shuttle valve chamber the pressure of this fluid forces the shuttle sealing element to the opposite end of the chamber.
