The Valve is located at fuelling stations throughout a ship. Model 302M maintains constant pressure and surge control during the fuelling operation of several types of aircraft during critical hot pit refuelling. The control valve also has the ability to defuel. The valve's unique three-ported design enables it to perform three different operations during critical hot refuelling operations.
