DOROT 70-550

Differential, 3-way / 4-way, Vertical Float-actuated Pilot Valve

DOROT 70-550, is a 3-way / 4-way, Foat-actuated Pilot Valve designed for level control valves. The float slides along the rod and positions the pilot control when it reaches either the high or low-level stoppers.
Operation principle
The pilot vents or pressurizes the main valve control chamber to open or close. The difference between high and low levels can be adjusted by positioning the stoppers on the float rod.
