Safety engineering company Smith Flow Control has manufactured a custom-built operating panel that enables operators to control a sequence of actuated valves. The operating panel can be used in a wide variety of applications that involve the use of actuated valves, for example to launch or receive a pipeline inspection gauge (pig).
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. The operator can select the valves to be closed using the panel. Red LED lights light up when the valves are fully closed. When all valves are closed, the operator can isolate the panel by removing the ‘A’ 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.
The panel has been designed with the operator and environment in mind, making it easy to use and robust. It is made to support applications in the most aggressive environments. It comes with an anti-reflective coating that eliminates glare and is suitable for temperatures ranging between -40° to +55° C.
The panel is designed to meet strict safety guidelines and regulatory body requirements. It is made using 316 Stainless Steel and conforms to Zone 1 Ex de classification and protection class IP66. It boasts of a compact design and can be used in weight restricted and space-limited areas.
