Installation & Adjustment
Installation
Install in a manner tension will not be applied to the coil section lead wire.
Hold the product body when carrying the product. (Do not hold onto the lead wire)
Piping
Dirt or foreign matter in fluid may prevent the product from functioning correctly. Install a filter finer than 80 mesh.
When the regulator and solenoid valve are directly connected, the parts could mutually vibrate causing resonance and chattering.
If the piping cross section on the fluid supply side is restricted, operation may become unstable because of a differential pressure fault when the valve
functions. Use a pipe that matches the port size on the supply side.
During Use & Maintenance
During use
Instantaneous leakage phenomenon
When using the 2 port pilot operated solenoid valve, sudden application of pressure (e.g. starting up a pump) could momentarily open a closed valve and

Operation
Do not place a back pressure. There is a risk of malfunction.
Water-hammer
If you experience a water-hammer problem, please consider using CKD "WHL-type" or "RSV-type" solenoid valve or a motor valve.
Differential pressure
Keep the differential pressure 0.02 MPa or above between the primary and secondary sides with the valve open.
