- *Internal pilot type: Be aware that the valve may not function properly even if the pressure on side 1 is within operating pressure range in the event that the flow rate on side 1 is insufficient due to throttling of the port, etc. See the manufacturer’s catalog for details.
- *Piping for external pilot type: Operation may be prevented if external pilot pressure is insufficient due to simultaneous operation, throttling of the air port, etc. If this happens, install a check valve (such as AKH Series) to the external pilot port, change to a port size that provides a stable pressure 0.25 MPa or above, or adjust the pressure settings.
