Combining the double check block with a built-in pilot type double check valve and a 3-position exhaust center solenoid valve will enable the cylinder to stop in the middle or maintain its position for long periods of time. The combination with a 2-position single/double solenoid valve will permit this block to be used for preventing the dropping at the cylinder stroke end when the SUP residual pressure is released. When the manifold is mounted. Top ported (VVQ2000-23A-C�ｭ) Bottom ported (VVQ2000-23A-B�ｭ) Single unit . 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 zero air leakage is not guaranteed, it is sometimes not possible to hold a stop position for long periods of time. . Combining double check block with 3-position closed center or pressure center solenoid valve will not work. . Set the cylinder load so that the cylinder pressure will be within two times that of the supply pressure. . If the exhaust of the double check block is restricted too much, the cylinder may not operate properly and may not stop intermediately. 15 22 80 65 . 10 55 15.8 Residual pressure release Manual override Residual pressure release Manual override Color: red 2 x port on the OUT side C3: With o3.2 One-touch fitting (for top ported) C4: With o4 One-touch fitting (for top ported) C6: With o6 One-touch fitting (for top ported) C8: With o8 One-touch fitting (for top ported) B3: With o3.2 One-touch fitting (for bottom ported) B4: With o4 One-touch fitting (for bottom ported) B6: With o6 One-touch fitting (for bottom ported) B8: With o8 One-touch fitting (for bottom ported) Double check block (Direct mounting) VVQ2000-23A-BC 1060 Series VQ2000
