The range of pneumatic control devices, manufactured by TECHNICAL comprises pneumatic pressure switches, servovalves, excess flow valves (all models in AISI 316L) while the liquid discharge valves with execution in carbon steel (A 350 LF2 or A 182 F5a). By working in the automation of the plant controlled by air network, these devices optimize, thanks to their precision of operation, the sequence of the process. Fall into this type of production also level switches with pneumatic signal, particularly appreciated in heavy work conditions.
