Direct-acting spool type sequence valves are compact and reliable pressure control devices in screw-in cartridge form, equipped with internal pilot and spring chamber vent. Sequence valves are designed to enable multiple circuits to operate in sequence in hydraulic systems. With their compact screw-in cartridge form, they offer easy integration into manifold blocks.
