Symbols. Pneumatic symbols are used to describe the function of the various valves and other devices which are connected together to form circuits and sub circuits. Pneumatically controlled devices use pneumatic valves to control and direct the air and enable operations such as lifting, moving, pressing,_etc.

What is a 5'2 valve? 5/2 way is a five port, two position valve that will put a fluid or_air into one end of a double acting device as well as allowing the other end vent to exhaust. Zero Differential are solenoid valves that can operate under zero head pressure (do not need a differential pressure drop across the valve to work).

What is the symbol for a check valve? An arrow or the symbol for any type of check valve (a fluidic/pneumatic logic symbol) on the outside of the body indicates flow direction.

What is a 3 2 valve? 3-Way/2 Position Valves. Three-way valves have three pipe connection s and two orifices. When one orifice is open, the other is closed, and vice versa. They are commonly used to alternately apply pressure to and exhaust pressure from a valve actuator or-a single-acting cylinder.
