❑ Verify all fasteners used are Grade 5 or better. Apply Loctite™ #242 or
equivalent, to any threaded fasteners used to install an adapter.
❑ Verify the valve body is
installed with the flow arrow
(
D
), embossed on the valve
body, pointing in the direction
of flow. (See Figure 3-1:
“Sample Embossed Arrow
and Adapter Mounting
Screws.”)
❑ Select an outboard adapter
suitable to the desired appli-
cation. Center the valve
body assembly onto the out-
board adapter and the pump
side adapter.
IMPORTANT !
WHEN MOUNTING ADAPTERS
TO THE SVS VALVE, TIGHTEN
AND TORQUE THE FOUR 3/8”-16 SCREWS TO 20 FT.-LBS. (27 N-M) IN A CRISS-
CROSS PATTERN TO ENSURE AN EVEN, WATERTIGHT SEAL. (SEE FIGURE 3-1:
“SAMPLE EMBOSSED ARROW AND ADAPTER MOUNTING SCREWS.”)
❑ Use joint sealing compound (e.g., Loctite PST or equivalent) on all NPT
(threaded) adapter fittings.
❑ If the valve-to-pump side adapter and/or the outboard adapter uses a
Victaulic™ fitting, connect the apparatus piping using the appropriate
Victaulic connector.
After lubricating the inner coupling seal with a Victaulic approved lubricant,
seat the coupling in both pipe connection grooves. Install the outer metal
split coupling body over the inner seal and tighten fasteners to the recom-
mended torque specifications.
❑ Use new gaskets and apply gasket adhesive as required.
❑ If an electric actuator is used, route the wire harness away from potentially
hot and/or moving parts. Secure the harness every 10” to 12” (254-309mm)
to insure against movement. Such movement could interfere with other actu-
ators and, in the case of cabled actuators, inhibit operation of the valve.
❑ After installation, verify the valve cycles properly from fully OPENED to fully
CLOSED without excessive effort. If equipped with a hand wheel or electric
control, verify the indicator lights sequence properly, indicating valve OPEN,
CLOSE, or IN BETWEEN. If a problem exists, see Section 5 “Troubleshoot-
ing” on page 21.
