Use a three-position mid-closed or medium-pressure reversing valve to stop the cylinder (biaxial or biaxial adjustable) piston in the middle In this case, since the air is compressible, it is difficult to stop at a precise and precise position. In addition, AIRTAC valves and cylinders cannot guarantee no leakage, so they cannot remain in the intermediate stop position for a long time. If you want to stay in the stopped position for a long time, you should use other methods.

2. Pay attention to the impact of back pressure on the system that may be generated when the valve manifold is used.

When the valve manifold is used, pay attention to the back pressure. Pressure may cause malfunction of the actuator, especially when using a three-position center-relief directional valve and when driving a single-acting cylinder. If there is concern about such malfunction, separate air intake and exhaust must be provided.

3. Fully consider the residual pressure release between the reversing valve and the cylinder

Considering the need for system inspection, the residual pressure release should be set function. Especially when using a three-position center-sealed air valve, it must be considered that the residual pressure between the reversing valve

and the cylinder can be released.
