Fluid control valve with sensor

A fluid control valve with a sensor, comprising:

• a valve main body including:
• an actuator section provided with a movable member including a valve element and configured to move the movable member;
• and
• a valve section provided with a valve seat with which the valve element will come into or out of contact;
• and
• a vibration sensor which detects vibration generated in the valve main body,
• wherein the vibration is generated by a water hammer phenomenon that generates impact when the valve element comes into contact with the valve seat and no fluid leaks between the valve element and the valve seat, and
• the fluid control valve further includes an abnormality determining unit configured to determine the valve main body to be normal when the vibration sensor detects the vibration with an amplitude exceeding a predetermined threshold, and determine the valve main body to be abnormal when the vibration sensor does not detect the vibration with an amplitude exceeding the predetermined threshold.
