OPW  10BF-5725 1-1/2 inch Single Poppet Emergency Shut-Off Valve - Female NPT

OPW 10BF-5725 1-1/2 inch Single Poppet Emergency Shut-Off Valve - Female NPT

Item #10BF-5725

Strategically designed to install beneath fuel dispensers at grade-level to minimize the hazards resulting from fire or collision 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, activating poppets and shutting off the flow of fuel. Equipped with 1-1/2 inch female NPT threaded outlets for fast- reliable connection. The 10BF-5725 is also equipped with a 3/8 inch test port.



  • Fire Protection – a fusible link trips the valve closed at 165º F to shut off fuel supply to the dispenser.
  • Main Poppet Seat Integral to the Top Assembly – having the main poppet seat as an integral part of the valve top ensures a new, clean seating surface is installed each time the top is replaced.
  • Duragard® Coat Finish – provides superior corrosion resistance.
  • Reliable Shut-off – a stainless steel main spring, a teflon-coated brass packing nut and a copper/nickel/ chrome-plated brass stem are designed to prevent tar build-up and corrosion from interfering with poppet operation after long periods of normal service without activation.
  • Integral Test Port – a 3/8" (9.5 mm) test port allows the piping system to be air-tested without breaking any piping connections.
  • Multiple Mounting Options – valves are boss-mounted to stabilizer bars in sumps and pans or mounted to bars embedded in the island with optional U-Bolt kits 10UBK-015 (not included).
