CHECK VALVES for pipeline installation, hydraulic pilot operated, pmax. 500 bar Description: These hydraulic check valves are part of the shut-off valves according to DIN ISO 1219. With a hydraulic inlet in the connection Z the blocked flow A→B can be opened. The flow B→A is permanently open. Pressure medium: Hydraulic oil 10 68 mm²/s, (ISO VG 10 to 68 according to DIN 51 519) The valve version with pilot control contains a spherical grinded valve piston with an integrated ball check valve. Already when opening the valve piston a throttle opening is released during the unlocking process. This dampens the pilot opening movement of the unlocking piston. Pressure surges in the load volume are suppressed by that. The pilot control ensures a lower opening pressure which is suitable especially for for swing clamp cylinders. The check valves without pilot control feature a ball as a valve element. Other designs are available on request A Application: The check valves serve for blocking the supply line in the application of hydraulic cylinders. The check valve with pilot control is ideal for high operating pressure and high consumer volume.
