Non-explosion-proof position feedback

Overview:

Non-explosion-proof valve limit switches, also known as pneumatic valve feedback devices, are mainly used in pneumatic butterfly valves and other pneumatic valves. Their function is to convert the on-off position of the pneumatic valve into a passive contact signal and provide feedback in the on-site PLC. The "OPEN" and "CLOSE" marks are displayed on the shell to facilitate on-site personnel in identifying the valve status
