DOROT 70-400

Modulating, 2-way, Float-actuated Pilot Valve

DOROT 70-400, is a 2 way, Foat-actuated, Pilot Valve designed to control constant-level control valves. The float-actuated pilot valve will vent / pressurize the control chamber of the main valve to open or close, in direct proportion to water level variations.
Operation principle
The pilot proportionally modulates, opens or throttle-closes the main valve; maintaining a constant water level, regardless of ﬂuctuating demand.
