MODEL 12F-TWO

Pressure/Vacuum Relief Valve

The Groth Corporation Model 12F-TW0-0 weight loaded pressure relief valve is designed
to be used in applications where additional relief is necessary. It can be used in conjunction
for emergency relief but that is not why it was designed. Pressure relief valves
provide relief from excessive internal pressure which may cause tank damage.
