DOROT S300 BC/PS

Diaphragm-actuated, Rigid Seal, Pump Control and Pressure Sustaining, Globe Valve

DOROT S300 BC/PS, is a Diaphragm-actuated, Rigid Seal, Pump Control and Pressure Sustaining Globe Valve. This automatic control valve is activated by the pressure of the pipeline. The valve minimizes pump starting/stopping surges by slowly opening at pump startup and slowly closing prior to pump shutdown. The valve maintains a pre-set upstream pressure, limiting flow velocity at line filling stages.

  • 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
