Service Valves, PVE1427 and PVE1449 Series (DOT)
NOTE: Sherwood’s internal excess flow valve has been field tested in both the US and Canada
on
3
⁄8-cubic inch (5.2-liter) and 400-cubic inch (6.5-liter) displacement engines. Analysis of
engine fuel requirements has confirmed that a 550 CID engine would consume less than 1.08
GPM under full load with a 50% safety factor. Restricting flow under 2 GPM minimizes the loss
of LPG in the event of a major break, while maintaining adequate flow for the LPG fueled engine
application.

PVE1427 Series Dot Cylinder Service Valves
for Fork Lift Truck Applications
t Integral excess flow check at inlet
t Flow rated at approximately 1.7 GPM LPG
t
For vapor or liquid withdrawal from fork lift truck containers
t PVE1427B — standard full size straight
3
⁄8" NPT outlet service valve
t PVE1427C — smaller body and bonnet assembly
t PVE1449 — smaller body and bonnet assembly, smaller diameter
handwheel, and lower profile than the PVE1427B and PVE1427C valves
Internal Excess Flow Valve
t Designed for both ASME engine fuel applications (PVE1447 Series) and
DOT fork lift truck applications (PVE1427 and PVE1449 Series)
t Because Sherwood’s excess flow device is internal to the valve body, it
is unaffected by internal variations in cylinder construction, which can
contribute to premature shutoff
t Designed with a low-pressure differential shutoff rated at 1.7 GPM
