You can measure the spring load and stroke of the spool without applying hydraulic pressure!
The device is designed to install a test specimen (3-mode valve assembly) onto an inspection manifold block and automatically perform pass/fail judgment by pressing the spool of the test specimen with a linear actuator to measure the spool's spring load, stroke, and the pressure discharged from each hydraulic port. Additionally, it is capable of measuring the spool's spring load and stroke without applying hydraulic pressure. It consists of a hydraulic unit and a DC servo motor-driven linear actuator. 【Specifications】 ■ Test specimen: Integrated VLV assembly ■ Hydraulic pressure: 300 kPa ■ Supply flow rate: 10 L/min ■ Spool pressing load: Maximum 20 N ■ Dimensions: Width 1.6 m, Depth 1.9 m, Height 1.7 m *For more details, please refer to the PDF document or feel free to contact us.
