FAQs:

1: Does the valve output air only when the button is pressed?

Yes. This is a momentary mechanical valve. Air flows only when the button is pressed. Once the button is released, the valve automatically returns to its original position and the air supply is cut off.

2: What is the difference between the 210 and 310 series mechanical valves?

The main difference is the body size and flow capacity.

210 Series: Compact size, suitable for applications with lower air consumption.

310 Series: One size larger than the 210 series, providing higher flow capacity.

410 Series: Larger than the 310 series and suitable for applications requiring even greater airflow.

The operating function remains the same; the selection mainly depends on the required flow rate and installation space.

3: Does the valve have a built-in filter?

Yes. The main air inlet of OLK valve is equipped with a built-in filter screen to help prevent dust and particles from entering the valve body, improving reliability and extending service life.

4: How do I choose between 4R210, 4R310, and 4R410 series valves?

If your application requires a small and compact valve, the 210 series is usually sufficient. For higher airflow requirements, the 310 series is recommended. For large pneumatic systems or applications with high air consumption, the 410 series is the preferred choice.

All three series provide the same operating function; the primary difference is valve size and flow capacity.
