r u MAHUAL PRESSURE BELIEF: <br />Another unique FE Petroa <br />feature. When necessary <br />9 C \ during maintenance to <br />bleed line pressure to zero, <br />a vent screw is provided. <br />By turning this screw, <br />line pressure is diverted <br />back to the tank. <br />J <br />`a <br />Reduces fuel discharge into the sump manhole or <br />dispenser pan during servicing, furtherprotecting <br />service technicians and the environment. <br />EETNG�UOIUIT. A RELIABLE CHECK VALVE: <br />The IST uses FE Petro's <br />Proven line check <br />valve. At 2 3/4" in <br />diameter, this valve <br />reduces pressure loss <br />at high flow rates, <br />resulting in faster <br />fueling times and lower <br />Power consumption. <br />The PE Petro check valve is proven to seal. You <br />can avoid purchasing additional check valves <br />when the I$T is used with some electronic line <br />leak detectors because of this proven reliability. <br />SUPERIOR BEARING COOLING: <br />The IST uses the <br />exclusive <br />FE Petro cooling <br />system. This unique <br />system continually <br />passes over 1 GPM <br />through a fine <br />bronze filter and <br />directly through <br />motor bearings <br />whenever pump is <br />operating. <br />This system has been designed to extend critical <br />bearing and motor life. <br />�1 J <br />UARt nu+rEp #"M- PRESSURE RELIEF VALVE: <br />The IST pressure relief valve is the same simple <br />valve used for years in our standard <br />submersibles. Factory set to relieve i" <br />at or above pump pressure. <br />c <br />This valve is protected <br />from particles in the. <br />fuel by a fine t. <br />mesh screen <br />JI <br />yinn: <br />By keeping static line pressure as high as <br />possible; mechanical leak detectors make <br />fewer tests, and therefore last longer. <br />The IST uses the <br />standard <br />FE Petro air <br />eliminator, <br />which has a <br />double function <br />as the syphon <br />primer for tank <br />syphon systems. <br />I AIR ELIMINATOR: <br />The air eliminator is a one way valve, allow" <br />air to return to the tank, but not reenter. the <br />piping system <br />W1r71A SYPHON CHECK YALYE: <br />Optional for syphoned tanks. <br />Another time proven performer., }' <br />`r 100 <br />- <br />The FE Petro syphon check valve can be <br />easily cleaned in the field. It is not necessary <br />to replace with a new valve if it becomes <br />blocked from particles in the fuel tanks, <br />
