Specification

Model 700XL • How to Order
The Model 700XL is available in a variety of inlet and outlet
sizes, thread types and connection types. Simply determine
the inlet and outlet connection as well as the location of the
union, then, select from the available configurations. The
inlet connection will always be specified first in the model
number. A union inlet connection with integral body outlet
connection is standard. For connections other than shown
below, such as BSP threads, contact your local WILKINS
representative or factory.
Example: A dual check valve is to be located on the outlet
side of a 3/4” water meter with male inlet and outlet con-
nections (see “Meter Thread Connections” on previous
page). The union will be located on the inlet side of the
valve. The outlet requires a 1” female NPT connection.
Inlet Outlet Model No.
