Cla-Val Model 302M is an Automatic Fueling and Defueling Control Valve
used to control pressure and surge on navy fueling systems such as
CVN, LHA, LHD, LPD and LPH Class vessels.
The valve is located at fueling stations throughout a ship. Model 302M
maintains constant pressure and surge control during the fueling
operation of several types of aircraft during critical hot pit refueling. 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
refueling operations.
The Model 302M valve is operated in conjunction
with Cla-Val Model 345GF Semi Dry-Break
Disconnect Assembly. The Dry-Break is equipped
with a continuity switch that makes and breaks signal
for pump control, as well as energizes a solenoid on
the 302M to start the refueling process.
The Model 345GF Semi Dry-Break Disconnect retains fuel in hose or
pantograph when disconnected. The unique butterfly valve configuration
of the 354GF seals tightly under any pressure and provides extremely low
pressure drop.
The 345GF is strong enough to withstand hydrostatic hose testing (when
closed/disconnected), provides easy access to the strainer in male
adapter when disconnected and functions as swivel joint when
connected.
