SVA SERIES ISOLATION VALVE ASSEMBLY
FOR INSERTION METERS

Used for pressures to 650 psig
1
(shown for use with
1/2" diameter insertion meters). Available sizes are
1/2" x 3/4" NPT (SVA05 shown), and 3/4" x 1" NPT
for use with 3/4" diameter insertion meters (SVA07).

1/2" tube x 1/2" MNPT pipe fitting (shown, not to
scale), is used for low pressure insertion applications
to 125 psig (Stainless Steel Ferrule optional for higher
pressure applications – up to 650 psig
1
). Also avail-
able in 3/4" tube x 3/4" pipe size.

1 At 650 psig, force exerted on 1/2" diameter probe is approx. 125 lbs.
2 Safety chain is designed to prevent probe from accidentally escaping from assembly during removal from pressurized pipe.
3 Insertion meters can have optional flanged mounting (generally used for high pressure or very hot gases). This adaptation is not
shown. Consult factory for details.
4 Maximum gas temperature, 200F, unless high temperature models ordered.
5 Hot Tapping is feasible by removing Weldment (upper portion of assembly temporarily removed).
6 Height of SVA07 is 12.50". Also, the SVA07 requires a 1"x1 1 ⁄

NOTE: User needs to weld a 3/4" female threadolet
(of appropriate radius) to mate with existing pipe
after a 3/4" hole has been drilled in pipe. The 3/4"
Male Coupling of the Sage Isolation Valve assembly
will thread into the user’s 3/4" threadolet.
