摘要：
Disclosed is a flow force compensating spool valve having a flow force compensating protrusion ring at a supply channel of a sleeve on an outer circumference portion of a spool rod, and a hydraulic valve, a pneumatic valve, a three-way valve, and a four-way valve using the spool valve, in which the flow force can be compensated by a simple structure change of the spool without changing a structure of the sleeve.
