Safety is critical in the manufacturing industry. Today, most manufacturers rely on a conventional system that detects danger and stops a machine during operation. In Japan, however, the trend is to utilize a Safety Monitoring System to monitor safety and allow a machine to operate after safety is confirmed. As new global safety standards are established, it is predicted that these Safety Monitoring Systems will be included in machine specifications at the design stage. Our Solenoid Valve with Monitoring Switch, Japan’s first Safety Monitoring System, is specially designed to meet the requirements of machine integration and safety.
The Nachi SAW Solenoid Valve mechanically detects the movement of the solenoid valve spool to activate the switch and to transmit an electrical ON/OFF signal. In other words, this valve monitors a spool operating condition and can be used for sequence control according to its ON/OFF signal. It is also an information source for confirming safety conditions.
