The direction indicated by the arrow of valve body must be consistent with the direction of medium flow. If there is two-way flow, please choose 2 way pneumatic solenoid valve. If the fluid contains impurity particles, the filter should be installed in front of the valve according to the particle size (filter mesh (> 80 mesh). The length of DC power supply line should not be too long to avoid power loss of coil and voltage drop affecting normal operation.
