ewo-stuttgart valves are directional control valves with more than two flow patterns and more than two oil ports. They are valves that realize the communication, cutoff, and reversal of hydraulic oil flow, as well as pressure unloading and sequential action control. Directional control valves rely on the relative motion between the spool and the valve body. There are two types: rotary valve type and slide valve type. They are classified into two-position, three-position, etc., according to the number of working positions where the spool stays within the valve body; they are classified into two-way, three-way, four-way, and six-way, etc., according to the number of oil circuits connected to the valve body; the methods for operating spool movement include manual, mechanical, electric, hydraulic, and electro-hydraulic.
