IF <J� OPW 10 SERIES L116-AGENCY SHUT-OFF VALVES DPW 10 Series Emergency Shut-off Valves are installed on fuel supply Patented Thermal lines beneath dispensers at grade level to minimize hazards associated with Low Profile Relief Valve collision or fire at the dispenser. If the dispenser is pulled over or dislodged , by collision,the top of the valve breaks off at the integral shear groove, Main Air Test activating poppets and shutting off the flow of fuel. Single-poppet models Poppet seat Pon shut off supply flow,while double-poppet models shut off supply as well as seconds prevent release of fuel from the dispenser's internal piping. The base of the Poppet ry Emergency Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within the dispenser sump or pan to ensure Fusible Link proper shearing action. The valve base is secured to the stabilizer bar using Nickel-Plated, a three-point boss mount system or with a U-Bolt Kit.Valve inlet(bottom) Teflon-Coated connections are female pipe threads and outlet(top)connections are Combination Main stem available with female threads, male threads,or a union fitting.
