Actuated valve control

The panel works as a communication and proofing system to improve efficiency and safety. A typical application often includes two interlocked key units to isolate power to the panel and ensure a specific sequence of operation.

Using the panel, the operator can select to close the valves. Red LED lights prove that the valves have reached their fully closed position.  When all valves are closed, the operator can isolate the panel by removing the ‘A’ Key.  The ‘A’ key is entered into the solenoid key unit and only when the SAS (safety and automation system) confirms all valves are closed, a permissive signal is sent to energise the solenoid and release the ‘B’ key.  This allows the operator to safely continue the mechanical interlocking sequence, for example, to manually unlock a pig trap door to load or unload a pig.
