DOROT S300 FR

Diaphragm-actuated, Rigid Seal, Flow Control Globe Valve

DOROT S300 FR, is a Diaphragm-actuated, Rigid Seal, Flow ControlGlobe Valve, activated by the pressure of the pipeline. The valve limits the flow rate in the system to a preset value, regardless of any upstream pressure variations. The valve fully opens when flow rate drops below a preset point.

Features & Benefits

Superior seat design, guided by the unique LTP (Linear Throttling Plug)
  • 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
