SAFETY VALVES

COMMON SAFETY VALVES ISSUES

The standard safety valve is similar to the standard pressure control valve with one main difference. Where the standard pressure control valve is used for operational purposes, the standard safety valve for used for safety purposes.

The malfunctioning of this type of valve can cause for greater damage. Due to Hydrocore’s simplistic design that requires minimal internal parts and no external parts, the chances for malfunctioning has been virtually eliminated.

HCA EXCESS FLOW SHUTDOWN VALVE WITH MANUAL ISOLATION FACILITY

HCS SHOCK PREVENTION VALVE

  • Description: A safety valve that prevents the occurrence of water hammer in the pipeline during an abrupt pump stop.
  • Applications: Mining, Industrial
  • Size Range: 50NB (2”) to 400NB (16”)
  • Pressure Range: 50NB to 100NB — 250 bar (3650 psi)

HC NON-SLAM CHECK VALVE

  • Description: A check valve prevents back flow while minimizing the water hammer effect during the valve’s closure.
  • Applications: Mining, Industrial
  • Size Range: 50NB (2”) to 400NB (16”)
  • Pressure Range: 50NB to 100NB — 250 bar (3650 psi)
  • 150NB to 400NB — 160 bar (2320 psi)

HC ENERGY DISSIPATER

  • Description: A valve that reduces high upstream pressure to a low downstream pressure into a water reservoir.
  • Applications: Mining, Industrial
  • Size Range: 50NB (2”) to 400NB (16”)
  • Pressure Range: 50NB to 100NB — 250 bar (3650 psi)
  • 150NB to 400NB — 160 bar (2320 psi)

THE HC NON-SLAM CHECK VALVE’S AMAZING COST SAVINGS BENEFIT

We have modelled a Standard Nozzle Check Valve (SNCV) to determine its Cv (see figures below). The table on the right shows the power penalty cost of a Hydrocore nonslam check valve (HC) versus a SNCV.

As is evident, the cost savings using a Hydrocore nonslam check valve versus a SNCV are astronomical even within the first couple of years. Assuming that the price of electricity is not going to go down in the future, those cost savings will only increase.
