Also known as 4 way and 5 2 valves.
Air control valve types.
Valve a are air to close type indicating if the air fails the valve will be fully open.
Flow control choices for air valves include unidirectional one way bi directional two way or three way.
The direction control valve generally refers to a conversion valve but more specifically it includes the conversion valve direct conversion valve check valve stop valve and shuttle valve.
B types of control valves based on number of plugs.
Pneumatic valves are one of an array of components responsible for controlling the pressure rate and amount of air as it moves through a pneumatic system.
The direct control valve controls the direction of airflow.
Directional control valves often used to extend and then retract a cylinder at different speeds these valves create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port.
Control valves can also be characterized in terms of the number of plugs present as.
Opposite is the case for valve b.
Pneumatic systems which depend on the force of compressed air to transmit power can be found in countless industrial applications from pneumatically operated power tools to diesel engines.
