Where does the remote-sensing pressure reducing control on the 362AF-8 hydrant control valve sense pressure from?

The remote-sensing pressure reducing control on the 362AF-8 hydrant control valve is designed to sense pressure from the hydrant servicing vehicle venturi. This aspect is crucial because the venturi system on the servicing vehicle operates under specific flow and pressure conditions that help regulate and control the fuel flow efficiently. By sensing pressure from this location, the system maintains the desired pressure levels and ensures that fuel is delivered safely and at the appropriate rate.

Sensing from the hydrant servicing vehicle venturi allows for adjustments that are aligned with the operational parameters of the vehicle and hydrant system. This integration helps prevent problems such as over-pressurization or insufficient fuel transfer, which are critical for effective operations. The other choices do not accurately reflect the correct operational context of the pressure sensing mechanism in relation to the 362AF-8 valve.
