Reducing and Regulating

Protection of Low Pressure Level Networks

  • Reducing an upstream pressure to an adjustable and regulated downstream pressure
  • To regulate multi pressure level networks
  • To supply water to a low pressure level network from a high pressure level network
  • To protect devices, installations or sections of the network against high upstream pressure
  • Direct acting pressure regulators often have simpler designs with no external sensing lines, they have a faster response time compared to a pilot operated pressure reducing valve and are also more compact in size. Direct acting pressure regulators however, are more susceptible to the “droop” effect under high flow rates, hence, often getting a lower pressure on the downstream side. Pilot operated pressure reducing valves are responsive to changes in the flow conditions whilst maintaining the accuracy of the set pressure point i.e. they help to reduce the effect of “droop”.
