MANUAL PRESSURE RELIEF: PRESSURE RELIEF VALVE: <br /> Another,unique FE Petro 19N. The IST pressure relief valve is the same simple <br /> feature.When necessary valve used for years in our standard <br /> during maintenance to submersibles.Factory set to relieve 0 <br /> bleed line pressure to zero, at or above pump pressure. # <br /> a vent screw is provided. This valve is protected .' <br /> By turning this screw, from particles in the <br /> line pressure is diverted fuel by a fine ti <br /> back to the tank. <br /> mesh screen. ° <br /> d <br /> Reduces fuel discharge into the sump manhole or <br /> dispenser pan during servicing,further protecting By keeping static line pressure as high as <br /> service technicians and the environment. possible,mechanical leak detectors make <br /> fewer tests,and therefore last longer. <br /> A RELIABLE CHECK VALVE: <br /> The IST uses FE Petro's AIR ELIMINATOR: <br /> proven line check The IST uses the <br /> valve.At 2 3/4"in standard <br /> diameter, this valve FE Petro air <br /> reduces pressure loss eliminator, <br /> at high flow rates, which has a <br /> resulting in faster double function <br /> fueling times and lower as the syphon <br /> power consumption. primer for tank <br /> syphon.systems. <br /> f µ l <br /> The FE Petro check valve is proven to seal.You <br /> can avoid purchasing additional check valves <br /> when the IST is used with some electronic line 7Their eliminator is a one way valve,allowing <br /> leak detectors because of this proven reliability. return to the tank,but not renter the <br /> g system. <br /> SUPERIOR BEARING COOLING: <br /> The IST uses the SYPHON CHECK YI4LVE: <br /> exclusive Optional for syphoned tanks. <br /> FE Petra coaling <br /> system.This unique Another time proven performer. 0c <br /> system continually <br /> passes over I GPM <br /> through a fine <br /> bronze filter and <br /> directly through <br /> motor bearings <br /> whenever pump is <br /> operating. <br /> �Petroon check valve can be <br /> ��r � �easily cleaned in the field.It is not necessary <br /> 7bearing <br /> s <br /> ippe toextend critical to replace with a new valve if it becomes and motor ltfey� - blocked from particles in the fuel tanks. <br /> ,�z :.mow s���„ ,� <br />
