DOROT S300L FLDI/PS

Diaphragm-actuated, Rigid Seal, Differential Float Level Control and Pressure Sustaining Globe Valve

DOROT S300L FLDI/PS, is a Diaphragm-actuated, Rigid Seal, Differential Float Level Control and Pressure Sustaining, Globe Valve. When this automatic, float actuated and pressure sustaining, pilot-controlled valve opens, it sustains a minimal required upstream pressure as water levels reach a set opening height and closes when it reaches a set lower/higher level. The differential between opening and closing levels is adjustable. In cases where the upstream pressure is lower than the set-value, the valve will maintain a closed position, regardless of the water levels.

  • Enables regulation to ‘near-zero’ flow as standard for all valve sizes
  • Provides high reliability and operational stability
Stainless Steel control port sleeves
  • Protects against corrosion and blockage, reducing time and cost on maintenance
Self-cleaning inline filter
  • Cuts down on frequency of inspections and maintenance, significantly reducing labor costs
Low cavitation index
  • Eliminates conditions leading to cavitation over a wide operating pressure range
No dynamic O-rings
  • Superior design reduces ongoing maintenance due to leakage or breakdowns
Safety air release
  • Easily removes air from the control valve chamber, to ensure stability and optimal system performance
