Metric Cartridge – 300 bar
Direct acting with external Pilot and Vent
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 design 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.
All External surfaces are zinc plated and corrosion proof.
All valve parts are made of high strength steel. Spool and cage are
hardened and micron finished to guarantee minimal wear and to
extend service life.
