Pressure & Flow Control Applications

Pressure control in a water a distribution system can be accomplished using various methods. There are five main methods of controlling pressure and flow. It is extremely important to get the correct pump, flow and pressure devices in any water delivery system so you have the best efficiency possible to save electricity and maintenance cost while maintaining the correct pressure and water volume to suit your application. The control method is dependant on many things and very application-specific.

Five methods of controlling flow:

  • Bypass Lines
  • Throttle Valves
  • Multiple Pump Arrangements
  • Impeller Trimming
  • Pump Speed Adjustments

Common pressure and flow control devices and systems:

  • Variable Speed Pump Motors (VSP)
  • Multistage Pumps
  • Pressure Switches
  • Digital Flow Meters
  • Pressure Relief Valves
  • Pressure Tanks
  • Air Release Valves
  • Ball Valves
  • Butterfly Valves
  • Check Valves
  • Needle Valves
  • Foot Valves
  • Gate Valves

Dowdens Designed & Manufactured Pressure Setting Spool Piece

As filtered water flows vertically from the surface the pressure at the mine level can be several thousand kPa. Normal orifice or flow restrictors induce high velocities in a very short space resulting in cavitation & sonic sound which can erode the components & reduce their effect.

Dowdens Engineering Department designed and developed a Pressure Setting Spool sized specifically to meet the specific duty required. The spool was custom designed using engineered fluid mechanics to reduce the pressure before it entered the valve station, taking part of the load off the station. Pipe supports were also engineered to provide a secure installation of the station.
