O P W4* <br /> 83= oonv" <br /> Overfill Prevention and Venting Equipment <br /> 71SO Testable Overfill Valve <br /> The OPW new patent-pending Testable 71504 Overfill Prevention Valve is the easiest, <br /> quickest and most cost efficient way to ensure that your overfill valves will operate <br /> when called upon - verifiable without removing them from the tanks. The OPW ILL <br /> 7150-T Testable Overfill Prevention Valve is the only UST Overfill Prevention Valve x <br /> that is testable from the surface without removal from the tank. <br /> 6150 & 7150 Overfill Prevention Valves <br /> §, ,. ... <br /> The OPW 61 SO and 71 SO vapor-tight Overfill Prevention Valves are two-stage I- i <br /> shut-off valves designed to prevent the overfill of underground storage tanks by <br /> providing a positive shut-off of product delivery. Models of the 61 SO and 71 SO are <br /> available to meet virtually any UST application, including two-point, coaxial, poppeted " <br /> coaxial and remote fill. The 71 SO vapor-tight model is designed for enhanced vapor x rTy ;s <br /> recovery (EVR) applications. Both the 61 SO and 71 SO are designed for use on tight-fill <br /> gravity drop applications only, and can be installed in the fill riser of both new and <br /> existing underground storage tanks. <br /> Ball Float Vent Valves and Extractor Fittings ry4 F <br /> OPW Ball Float Vent Valves protrude into underground storage tanks from the <br /> Stage I vapor return riser pipe. As the tank becomes full during a product drop, the <br /> ti <br /> ball seats most restricting the flow of vapors back to the transport truck or through <br /> the tank vent. As the vapors are compressed in the tank, product flow into the tank {. <br /> is severely restricted. <br /> OPW ball floats are mounted in OPW extractor fittings to maintain access through r <br /> grade-level manholes. ; <br /> g F ➢ bxr " <br /> Drop Tubes and Accessories4 } <br /> OPW drop tubes are installed inside tank fill risers to prevent fuel from contacting riser c <br /> joints. Drop tubes extend close to the bottom of the tank to minimize turbulence and <br /> vapor production. Tank bottom protectors are installed on the bottom of drop tubes to <br /> prevent tank erosion at the fill point. <br /> 114 Lt <br /> Pressure Vacuum Vents and Adaptors . <br /> Pressure Vacuum Vents are installed on the top of vent pipes from underground or m " s }� <br /> aboveground fuel storage tanks. The vent cap and internal wire screen are designed _ <br /> to protect the tank vent lines against intrusion and blockage from water, debris or <br /> insects. A normally closed poppet in the valve opens at a predetermined pressure or <br /> vacuum setting to allow the tank to vent. <br /> f <br /> 3. 1141 21t t <br /> 14IV 41 <br /> LII <br /> 110 9393 Princeton•Glendale Road .
