During the assembly process, the valve does not switch when manually operated (internal pilot) 5-way valve. The cylinder is not piped for the time being and is in an open state of atmosphere.
When the 2 (B) and 4 (A) ports of the valve are not piped and compressed air is continuously released into the atmosphere from the valve port, the internal pilot pressure used to switch the main valve will not increase to the necessary minimum pressure, which may cause the main valve to fail to switch.
Please manually operate the valve after the cylinder is piped.
