Supply/Exhaust port The diameter of the port orifice has been enlarged to support high speed operation. Relief valve adjusting screw Relief valve body The relief valve body rotates 3, enabling relief adjustment from any direction.

Relief valve The relief valve is used as a cushion valve and it provides better cushioning performance than a needle throttle of a general purpose cylinder. pplication Examples Opening/closing doors ( mm/s, several tens kg) Transfer equipment kg, mm/s (For ø) High speed Z-axis (Up to 3 mm/s, several kg) Relief valve body 2.

Transferring to the opposite stroke, air passes through the cushion seal that functions as a check valve, and starts to push the piston. The cushion ring travels past the cushion seal, and the stroke becomes the opposite of step 1, and the movements shown in steps 1 through 4 above are carried out on the head cover side.

How to Rotate the Relief Valve ody (ø, ø, ø, ø) aution The relief adjusting screw can be placed in any direction by rotating the relief valve body by following the steps given below. Procedure 1. Verify that there is no residual pressure in the cylinder. Then, loosen the mounting bracket (such as foot, flange, etc.). 2. Loosen the set screw that is provided in the relief valve body retainer and rotate the relief valve body. 3. While keeping the relief valve body retainer pressed against the relief valve body, secure it with the set screw. fter having secured the relief valve body retainer, make sure that the relief valve body cannot be rotated. In the event that it does rotate, loosen the set screw again and repeat the operation described in step 3. Set screw Relief valve body retainer Relief valve adjusting screw Relief valve body Move slightly Handling aution 1. onfirm that the relief valve body does not rotate when the cylinder is mounted. If there is play in the axial direction of the relief valve body, the cushion may become ineffective. When attaching brackets (foot, flange), do so after loosening the relief valve body set screw. Retighten the relief valve body set screw after the brackets have been attached. (ø,,, ) 2. The cylinder stroke end cushion adjusting screw is adjusted six turns ( turns for ø3, ø and ø) starting from the position where it is rotated fully clockwise to counterclockwise (fully closed). It should never be rotated more than six turns (more than turns for ø3, ø and ø) from the position where it is rotated fully counterclockwise (fully open). This may damage the spring inside the relief valve. Lateral load Relief valve adjusting screw 3. The cylinder ports are designed so that a maximum speed 3 mm/s can be obtained. However, it may not be possible to attain the desired speed in the case of short cylinder strokes. It may also be impossible to attain the desired speed due to restriction by component equipment (valves, speed control valves, piping, fitting, etc.). Make every effort to ensure sufficient effective area in the component equipment. 4. void applications in which lateral loads are applied to the cylinder piston rod. Especially in the case of long strokes, implement measures such as providing a guide for the load.
