VIS Hydraulics SQC2.S08

The SQC2.S08 is a screw in, cartridge style, direct acting, spool type hydraulic sequence valve with internal pilot. This valve has aspring chamber drain and is designed to direct oil to a secondary circuit once a predetermined pressure level is reached in theprimary circuit. In the idle condition, the SQC2.S08 blocks flow at 1, and also allows no connection between 2 and 3. Once pressuresetting is reached, the spool shifts and puts in connection ports 1 and 2, while blocking flow at 3. Note that the back pressure at port3 is directly additive to the spring setting value.
