valves can:
open and close flow paths
regulate pressure
adjust flow volume
direct flow through various paths

directional control valves: 3/2,
5/2 control valve - for double acting cylinders

5/3 control valve - can be used in controling the position of a double acting vane cylinder
application - can hold various positions for ergonomics - the operator can start and stop the bin at any angle
AND valve - both buttons need to be pressed for the valve to open
AND valves are also called two pressure valves
OR valves - aka shuttle valves
OR application - can be used to start an operation with a push button or a foot pedal
Quick Exhaust Valve -
Pressure Valves - pressure regulator
flow control valves
one way flow control valve - consists of an adjustable flow control and a check valve
application - can control the speed of the actuator in one direction and full speed in the other
Combination Valves
Sequence Valve - the valve switches when a predetermined pressure is reached

In the application below the cylinder presses a bushing into a housing. The cylinder extends and retracts when a certain pressure is reached.
Another Combination valve is the Time Delay Control Valve
It consists of a one way flow control valve, air reservoir and directional control valve
application - can be used to hold the cyliner position for a few seconds before the next cylinder fires
