Directional control valves

Spool-type directional control valves have integrated sensors to signal spool position. D03 valves operate to 5000 psi with direct and piloted valves standard at up to 4600 psi. D05H to D08 sizes operate up to 6000 psi. Inductive proximity sensor with closed contacts indicates spool position when valve is de-energized. Through connection to electronic logic device, it recognizes state of valve and indicates spool movement when energized.
