The CKD 4GB140R-06-E2A-3 is a pilot-operated, 5-port solenoid valve from CKD’s 4GB1R series, built for sub-base (manifold) mounting rather than in-line body piping. Because the valve seats onto a mounting base rather than being piped directly, it can be removed and replaced for service without breaking into the surrounding air lines, which is a configuration commonly used in pneumatic control panels where valves are grouped on a manifold to direct air flow to cylinders and other actuators. This unit is built with Rc 1/8 ports and a 24 VDC solenoid coil, and as an “R” series valve it includes a built-in exhaust check valve, which helps prevent air from flowing back through the exhaust port in a way that could disturb the connected actuator.
Since CKD’s 4GB1R sub-base valve line spans a range of port sizes, coil voltages, electrical connection types, and solenoid configurations, matching the complete 4GB140R-06-E2A-3 designation, not just the base 4GB140R model number, is important when replacing a valve or fitting it to an existing sub-base/manifold assembly.
