PVP-SYSTEM
Measuring, storage and control device for injection parameters, able to control up to 2 injectors
INDUSTRY 4.0 READY
The operator can easily control and drive up to 2 injectors together. The control of the injection can be manual (START-STOP) or automatic according to the achieved limit of pressure or volume or to the Gin number previously set up. The system also manage the switch from high to low pressure and the continuous adjustment of the injection flow, controlling the proportional valve of the injector (where is available).
PVP SYSTEM is already equipped with the capability to be connected to a 3G, or wireless or Ethernet network so that it could be remotely monitored giving the chance to load programmed injection recipes into the system, download data collected or run maintenance tests and procedure.
The parameters can also be displayed on the customer's fleet management portal, where all the customer's devices along with their locations, acquired datasets, and a real-time telemetry dashboard can be viewed.

Info Request
PVP-SYSTEM is a system for the measuring, storage and control in the soil consolidation process with grout injections; thanks to a 10” touchscreen display, the system can control up to 2 injectors with just a box and one display that could be 7” or 10 “.
The system has the dual function of automatically control the injectors and of measure/supply the characteristic parameters by which the injection has been carried out for statistic control analyses. For each injection, the device allows to measure and store the following parameters:
Parameters measured
- Injected mixture pressure
- Injected mixture instantaneous flow rate
- Injected mixture volume
- Valve break pressure
- Maximum Pressure in low pressure phase
- Final pressure
Plant Management
- Injector START-STOP automatic control
- HIGH-LOW pressure automatic control
- Proportional valve automatic management
- Pressure controlled injection, max. volume and GIN automatic management
Management can be carried out using manual commands (START-STOP) or automatically once the previously set pressure limit, volume, or number of Gin is reached.
The instrument also manages the switch from high to low pressure for each injector and the continuous adjustment of the instantaneous injection flow rate by controlling the injector's proportional valve (if equipped), allowing the injection flow rate to be gradually reduced in order to achieve a higher filling factor without the risk of injecting at excessively high pressures.
For each concrete injection, the system stores the name of the injection, the valve number, the mixture type, the duration of the operation, the date and time of execution, the number of the injector used, the default limit values (max. pressure, max. volume and GIN number), and the cause of the injection stop. The LCD displays the trend in time of the pressure and instantaneous flow rate for each ongoing jet operation or it allows to monitor simultaneously the state of 8 injectors with the values of flow rate, pressure and volume.
By using VISUAL-SGD software, it is possible to carry out the statistical analysis of stored data during the operation, as well as other quality controls, including the printing of records with the typical graphs of each injection executed. It is possible to customize the printing configuration by modifying the display scales, the printing colours, etc. following the customer needs. You can display and print a final report (e.g., for the current day) such as a list of the injections carried out, including the main values for each operation as described above. The START-STOP and HIGH-LOW PRESSURE controls is given by electric contacts. The system is equipped with linear variable outlets for the direct control of proportional valves: these manage the flow rate of the injectors in order to inject even minimum quantities of mixture by achieving a higher level of refilling without the risk of sudden changes in pressure.
