Technical Information
General Description
Series 21100 Exectrol directional control valves are
direct solenoid operated 4-way control valves. A slide
and balanced seals are used which provides near zero
leakage. The valves have a high tolerance to media
contamination as each movement of the slide wipes
the sealing surfaces clean which in turn results in long
service life.
Internal 8 drops per min. maximum
