10 Series Emergency Shut-Off Valves
OPW 10 Series Emergency Shut-off
Valves are installed on fuel-supply
lines beneath dispensers at grade-level
to minimize hazards associated with
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, activating
poppets and shutting off the flow of fuel.
Single-poppet models shut off supply
flow, while double-poppet models shut
off supply as well as prevent release
of fuel from the dispenser’s internal
piping. The base of the emergency valve
is securely anchored to the concrete
dispenser island through a stabilizer bar
system within the dispenser sump or pan
to ensure proper shearing action.
The
valve base is secured to the stabilizer
bar using a three-point boss mount
system or a U-Bolt Kit (not included)
10UBK-015 (1-1/2") and 10URK-0200
(sold separately).
Valve inlet (bottom)
connections are female pipe threads
and outlet (top) connections are
available with female threads, male
threads or a union fitting.
Other options
include suction system models with a
normally closed secondary poppet which
maintains prime, and models
with external threads on the inlet
body which connect to secondary containment systems.
