Combining with a 3-position exhaust center solenoid valve will enable the cylinder to stop in the middle or maintain its position for a long time. Combining with a 2-position single/double solenoid valve will prevent a cylinder from dropping at the stroke end when the residual pressure of SUP is released.

Air leakage from the pipe between the valve and cylinder or from the fittings will prevent the cylinder from stopping for long periods of time. Check the leakage using neutral household detergent, such as dish washing soap. Also, check the cylinder’s tube gasket, piston packing and rod packing for air leakage. . Since One-touch fittings allow slight air leakage, screw piping is recommended when stopping the cylinder in the middle for long periods of time. . Combining double check block with 3-position closed center or pressure center solenoid valve will not work. . When fittings, etc. are being screwed to the double check block, tighten them with the torque below. . If the exhaust of the double check block is restricted too much, the cylinder may not operate properly and may not stop intermediately. . Set the cylinder load so that the cylinder pressure will be within two times that of the supply pressure.
