Intelligent Pressure Modulation System with Bi-Directional Communication

Pegasus+ is a pressure regulating valve (PRV) control system for waterworks, which allows the outlet pressure to be adjusted according to time, demand or a combination of both.

In addition to adjusting pressure on demand, Pegasus+ is able to monitor critical points in the network thanks to its integrated cellular communication and coupling with the central management system DataGate/Pressview.

This optimal management of the pressure in the various zones of the network significantly reduces the risk of leaks and pipe breaks, thus ensuring more reliable, trouble free and economical operation of critical drinking water distribution infrastructures.

Pegasus+ is compatible with the vast majority of commercially available valves and can operate autonomously on battery power, making it possible to use on existing installations without the need for renovation.


Modulation of the distribution pressure of water networks based on demand.

Pegasus+ is particularly important when the network presents critical points (e.g., high points) because it then allows the optimization of the network pressure while ensuring adequate pressures at these critical points.

These critical points are generally equipped with Multilog LX2 type data loggers which communicate with the Pegasus+ system via the DataGate/PressView supervision platform.

Pegasus+ can be used with the vast majority of commercially available control valves, both new and existing. The hydraulic actuator supplied with the controller is simply installed in place of the nut used to set the valve (pilot) output pressure.

Pegasus+ can also be connected to existing flowmeters for control applications on demand or can be implemented with electromagnetic insertion flowmeters (see HydrINS2 and TORPEE-MAG products).

Main benefits

  • Flexibility and adaptability of the solution (implementation in new or existing valve chambers, on all brands of valves)
  • Operational safety:
    — minimum and maximum pressure values mechanically adjusted and locked on the hydraulic actuator of the Pegasus+; avoids any total closure of the valve in case of improper handling by an operator, electronic problems, breakage or freezing of the pipe
    — Incident monitoring (defective sensor, abnormal flow ...) with automatic switch to degraded mode (fail safe function)
    — automatic forcing of maximum opening or closing in extreme or emergency situations (e.g., needs for fire hydrants)
    — Accelerated monitoring and recording of pressure transients
    — integrated alert capabilities
    — traceability of operators' actions
  • Regulation associated with monitoring of critical points in the network
  • Possibility of use on sites without power thanks to long-lasting internal batteries (autonomy of about 5 years)
  • Availability of external battery packs to increase this duration
  • IP68 (submersible), 316 stainless steel connectors
  • Integrated telemetry compatible with the new LTE-M/NBIoT cellular networks that offer:
    — better communication in difficult locations (e.g., underground rooms)
    — reduced energy consumption
  • High level of security of communications, with SMS backup in case of reduced availability on the Data IP channel of the networks.
  • Configurable remotely
  • Recording of upstream and downstream pressure measurements and flow rates
