Flange Seal Liquid Transfer Angle Valves for Bulk Storage Containers
Info
Designed especially for liquid transfer of LP-Gas from consumer bulk
storage containers when used with a Chek-Lok® or equipped with
an integral excess flow valve. May also be used for vapor LP-Gas
service.
In NH3 applicator tanks they may be used as a vapor bleeder valve
or as a liquid withdrawal valve when installed in a coupling with a dip
pipe.
These liquid transfer valves are equipped with an integral excess
flow valve for liquid transfer directly from the tank fitting, or without an
integral excess flow for LP-Gas transfer through a Check-Lok®.
When equipped with an integral excess flow valve (7550PX), the
valve should be mounted in a forged steel 3000 lb. half coupling.
When mounted in a 1¼” x ¾” NPT reducing coupling, the ¾” female
thread in this coupling must be full length — equivalent to a forged
steel 3000 lb. half coupling.
The excess flow valve will not function properly if these specifications
are not met. Refer to the Warning Bulletin in the Excess Flow Valve
Section of this catalog.

* To obtain approximate flow at other than 1 PSIG pressure drop, multiply flow in table by square root of pressure drop. Example: 7550P @ 9 PSIG = 13.3 x 9 = 39.9 GPM/propane. For NH3 flow, multiple propane flow by .90.
* * For NH3 flow, multiply propane flow by .90.
