Line valve control system

Line valve control

The line valve control system is designed for automated remote or manual control of a line valve with an electro-pneumatic control unit. The power is supplied from a solar module, and it features diagnostics of valve site technological parameters, and continuous 24-hour operation. The system can be used independently or as part of a telemechanics system.
The equipment included in the system has the following explosion protection markings:
  • «2Exе[ib]IIBТ5 X» for the BU-025 control unit;
  • 1ExibIIВT5 Х for the DI-017 excess pressure sensors;
  • 1ExibIIAT5 X for the RG model of the HyperFlow-MK mini-communicator;
  • 1ЕхdIIВТ3 for the resistance temperature transducer.

The system provides:

  • control over opening and closing a linear valve;
  • measurement and monitoring of gas pressure before and after the valve, as well as in the reserve tank;
  • measurement and monitoring of the gas temperature after the valve, the battery and the ambient temperature;
  • signaling of the valve position, continuous monitoring of breakage or shorting of solenoid circuits;
  • signaling of deviation of technological parameters beyond the set limits;
  • signaling of unauthorized equipment state change;
  • signaling of unauthorized access to the site;
  • signaling about abnormal situations.
