Cartridge directional 2 2 way valves are intended to act as a blocking or load holding device for low flow circuits.
The at rest box or the normal condition is the one with the flow lines going to and from it.
A 2 way directional valve has two ports normally called inlet and outlet.
These two valves vary simply by the fact that one has a normally open passageway while the other has a normally closed one.
The normally closed 2 position and 3 way pneumatic solenoid valve means that the gas circuit is off when the coil is not powered on the inlet and the outlet are shut off or that a and p are disconnected with power off a and t are connected with power on.

When the inlet is blocked in the at rest condition as shown in figure 8 1 it is referred to as normally closed nc.
If the 3 way valve is needed for more complex functions either the 3 way directional control or the 3 way multipurpose valve can be used.
Circuit function of a normally closed 3 2 way valve most valves are mono stable and return to their default position when not actuated this is achieved with a spring mechanism.
