1 Example: The figure below is based on the condition of set values as P1 = 40 [kPa] and P2 = 20 [kPa].
mm Round head combination screw Note) DC AC CEcompliant LN, MN type: With 2 sockets.
The valve element of the C.O. type, which has no return spring, is in an arbitrary position when air is exhausted through the ports 12(P1) and 10(P2). When pressurized air enters the port 12(P1) (exhaust from the port 10(P2)), the valve element opens, and it closes when pressurized air enters the port 10(P2) (exhaust from the port 12(P1)). Component Parts No.
(Return spring normally open) In contrast with the N.C., when the pilot solenoid valve is not energized (or when air is exhausted from the port 10(P2) of the air operated type), the valve body is opened by the return spring. When the pilot solenoid valve is energized (or when pressurized air enters through the port 10(P2) of the air operated type), the valve body closes.
Pilot port P1 and P2 piping Please arrange P1 and P2 piping as follows according to the model.
"LN", "MN" types: with 2 sockets. For connector cable of M8 connector, refer to page 562.
