Here we have a Hale Master Intake Valve Manual Override Wheel replacement. It is used on an electric-operated valve but used to provide an additional means of manually operating the MIV valve in case of an electrical failure.
In the event of a malfunction, the Manual Override Wheel allows the MIV to be operated manually, ensuring that the pump can be isolated from the system if necessary. It ensures that the fire pump system remains functional even in an emergency situation. If yours is broken, get a new one today!
