Signal Switch Feedback Device
The feedback signal of the limit switch is combined to indicate the valve opening and closing position. The appearance design is exquisite, and the installation with the actuator is more compact and convenient. The device can effectively monitor the specific switching status of the valve and realize the local and remote monitoring functions.
Precautions for testing and maintenance:
When testing or repairing the fused emergency shut-off valve, the switch device (valve) installed upstream must be turned off. The fused emergency shut-off valve only operates in emergency situations. In order to enable it to operate correctly in an emergency, it should be manually opened and closed more than three times a year to avoid debris deposits or other conditions that may cause the valve to not work properly.
