TTS Series 104R – Vapor Recovery Regulator / Back Pressure Relief Valve With Integral Vacuum Relief and Weight Loaded Relief with Flame Arrestor

Model 104R is pressure vacuum relief valve with integral flame arrester and diaphragm type vapor recovery regulator / back pressure relief valve with weight loaded relief valve.

It is designed to protect your tank from damage created over pressure or excessive vacuum with bubble tight shut off technology. At the same time it provides protection from externally caused sources of heat and ignition with integral flame arrester.

The vapor recovery regulator controls vessel vapor pressure / blanketing gas pressure when the vessel is being filled with fluid or when ambient temperature causes the vapors to expand the system monitors. The increasing blanketing pressure and throttles open to pass excess blanketing gas into a vapor disposal or reclamation system thus controlling the desired set pressure of the tank. The product vapors can be discharged through the pipe away connection flange which may be connected to a vapor recovery condenser or scrubber. If there is further increase in pressure due to any abnormal condition weight loaded relief valve will be in operation. When the set pressure is reached the pressure pallet lifts and relieves the tank pressure to the atmosphere.
