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.

2-way float-actuated pilot valve
  • Controls main valve operation by modulating valve in direct relation to changes in water levels; ensuring water-level stability.
Soft closure regulation
  • Provides smooth regulation, preventing abrupt pressure changes that can cause system instability.
No overflow – drip-tight closure
  • Prevents overflow by providing a secure shutoff when maximum preset water level is reached.
Inlet flow equalized to demand flow
  • Helps maintain a constant water level, even under fluctuating system demands.
Wide application range
  • Suitable for use with any hydraulic control valve; versatile and easy to integrate into diverse systems.
Simple, easy installation and maintenance
  • Offers straightforward setup and low maintenance; reduces operational downtime.
