Detailed Safety Instructions


1.To adjust the speed of the actuator, gradually turn the needle from the fully closed position to increase the air volume. If the needle is open, there is a risk of the actuator move suddenly and violently. Turning the needle clockwise closes the valve, while turning it counter-clockwise opens it.

2.When adjusting the flow rate of the equipment, the needle should be turned to open gradually from the fully closed position. If the needle is in open position, a high flow rate will be instantly applied to the equipment and there is a risk of damage to it.

3.After the threaded body is tightened, the resin body must be rotated in a clockwise direction when adjusting the tube fitting port position, as the screws may loosen.


1.Leakage is allowed for the control flow even when the needle is fully closed position and should not be used in such a way that zero leakage is required.
