The pneumatic-manual double-control rotary valve relies on the integrated pilot air circuit and worm gear compound transmission, and performs excellently in the emergency cutoff of industrial processes. Its pneumatic-assisted design not only achieves a fast switching response of ≤0.5 seconds, but is also widely used in petrochemical ESD systems, dust explosion-proof isolation cabins, and pharmaceutical sterile pipelines, especially in Ex ia IIC T6 explosion-proof scenarios to maintain IEC 61508 SIL3 level safety interlock reliability.
It is widely used in the on-off logic control of pneumatic circuits in industrial automation, the start-stop safety interlock of vacuum systems in packaging machinery, and the safe switching of ventilator gas circuits in medical equipment. It also has significant application value in other industrial fields.
Description
