Materials
Top: Cast iron
Body: Cast iron
Disc: M-19
Carrier: Zinc-plated steel
Stem: Copper-nickel-chrome-plated brass
Poppet spring: Stainless steel
Seal: M-19 O-ring
Packing Nut: Brass, Teflon-coated
Inlet and outlet thread: 1 1/2″ (4 cm) NPT (British threads available)
With black Duragard E-coating
Features
High Flow Capacity – The primary poppet is held out of the flow stream while the secondary poppet is held normally open to minimize head loss across the valve and to protect the poppet seals from damage and erosion. True 1-1/2″ (4 cm) and 2″ (5 cm) body sizes ensure maximum flow.
Fire Protection – A fusible link trips the valve closed at 165° 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 assures a new, clean seating surface is installed each time the top is replaced. This design also ensures that the integrity of the seal between the valve top and bottom is verified during line testing and allows full inspection of the main poppet when the top is removed.
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.
Patented Thermal Relief Valve – Relieves excessive pressure over 25 psi caused by thermal expansion of fuel in the dispenser piping system in the event of fire (double-poppet models only).
