DOROT S300 PS[R]

Diaphragm-actuated, Rigid Seal, Pressure Sustaining/Relief Globe Valve

DOROT S300 PS[R], is a Diaphragm-actuated, Rigid Seal, Pressure Sustaining/Relief Globe Valve activated by the pressure of the pipeline. The valve maintains a steady, preset pressure in the network, upstream of its location. Should upstream pressure exceed preset values, the valve opens to increase network flow, reducing the upstream pressure. Should upstream pressure fall below preset values, the valve closes drip-tight.

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
