One-way flow control valves
One-way flow control valves combine the functions of flow control valves and shut-off valves in a single component. The compressed air flows freely in one direction. The flow rate can be changed in the reverse direction by an adjusting element. These products are often used in combination with pneumatic cylinders in order to control the speed.

What is a non-return valve or a check valve?
Non-return valve, also known as check valves, is a mechanical device that allows fluid or gas to flow in only one way valve. Stopping reverse flow and protecting against damage or malfunction in piping systems, pumps, and other mechanical equipment.

Types of non-return valves.
Basically, the following valves come under this category:

Check valves,

One-way valves,

Quick exhaust valves,

Shuttle valves (OR valves) and

Dual pressure valves (AND valves).

Check valves
Check valves are used very frequently in pneumatics. Applications range from the simple shutting off of flow directions and speed control through to logic operations. They are also used in cases where individual components are to be isolated in a circuit in order to eliminate mutual pressure induced effects or to prevent the exhausting of units or entire system sections in the event of pressure failure. Check valves can prevent water hammer. Lift check valve, swing check valves, ball check valve, diaphragm check valve or wafer check valves go under this category.
