DESCRIPTION

The SQD0.M22 is a screw in, cartridge style, direct acting, spool type hydraulic sequence valve with external pilot. Spring chamber

is constantly air vented. The valve is designed to open flow connection between two ports that were previously blocked. In the idle

condition, the SQD0.M22 blocks flow between ports 2 and 3. Once pilot pressure at 1 attains the spring setting the spool shifts and

allows flow between ports 2 and 3 in both directions.
