OPW 10 SERIES E ERGENCY SMUT-OFF VALVES OPW 10 Series Emergency Shut-off Valves are installed on fuel supply lines beneath dispensers a1 rade level to minimize hazards associated with Patented Thermal p g Law Profile Relief Valve collision or fire at the dic;.enser.

Single-poppet models Poppet Seat shut off supply flow,while double-poppet models shut off supply as well as secondary prevent release of fuel from the dispenser's internal piping. The base of the Poppet 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.
