PI73-SS Pressure Intensifier

Brand: Bifold
Request Information
The P173-SS Intensifier amplifies the inlet pressure to a higher outlet pressure by a predetermined ratio for any given model.
 
Pressure in the high pressure line can become reduced as a result of a system leak or the use of the stored (pressure) energy. Using virtually no energy, the P173-SS restores and maintains that pressure in such instances. Rapid adjustment of the high pressure line can be achieved by varying the inlet pressure as the high pressure is directly proportional to the inlet pressure.

Check and changeover valves are integrated within the main body of the intensifier as is the pilot-operated vent valve for the versions in which it is incorporated. When the inlet pressure x the ratio = the outlet pressure, then the P173-SS is in a stalled condition and there is no consumption of fluid. The maximum outlet pressure is 1380 bar.

With the model incorporating the pilot-operated vent valve, that valve is normally held closed by the input pressure. If for any reason the low pressure supply is interrupted, the system floods with zero pressure "tank" fluid. In such a circumstance, the pilot-operated vent valve is no longer held closed by the input pressure - it opens so that the high pressure is safely vented away.

Features

  • Designed to boost the pressure of any water-based or mineral/synthetic oil-based fluid
  • Boosts inlet pressure up to 7 times without external power.
  • The maximum outlet pressure is:
    • psi:  20,020
    • kPa: 138,000
    • bar:  1,380
  • When system pressure is achieved, there is minimal consumption of expensive hydraulic fluid
  • Manufactured from 316 (standard), or from duplex stainless steels; no painting required for hostile environments
  • Costs reduced - no electrical suppl y or controls required
  • Production quality to the stringent standards required for hostile subsea environments
  • Two versions - with and without a pilot-operated vent valve for the high pressure line

Applications

The P173-SS was designed principally for applications in the offshore oil and gas industry where the highest standards of product performance and durability are essential.

The P173-SS is manufactured from 316 stainless steel to withstand hostile environments; it can operate on all water-based glycol fluids or on mineral and synthetic oils.

The PI73-SS Pressure Intensifier is ideal for charging accumulators from a low pressure umbilical; it may also be used for operating several different systems from a single supply.
