The valve element for the C.O. type, which has no return spring, is in an arbitrary position when air is exhausted through the ports P1 and P2. When pressurized air enters the port P1 (exhaust from the port P2), the valve element opens, and it closes when pressurized air enters the port P2 (exhaust from the port P1).

In contrast with the N.C., when air is exhausted from the port 10(P2), the return spring opens the valve element. Pressurized air that enters through the port 10(P2) closes the valve element. Component Parts Material Bronze No.
Example: The figure below is based on the condition of set values as P1 = 40 [kPa] and P2 = 20 [kPa].
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.
