Maintenance Procedures
Valve Identication
Installation Instructions
The WILKINS Model 48 Resilient Wedge Gate Valve can be distinguished from other gate valve
brands by observing the unique lettering on the valve body. One side designates the valve size,
model, pressure rating, year of manufacture, and the UL/FM logos. The opposite side displays the
valve size and “WILKINS” in vertical lettering. See pictures below.
Gate valves that do not contain the name WILKINS in raised cast letters on the valve body are not
WILKINS brand.
Proposition 65 Warning This product contains chemicals known to the State of California to cause cancer or birth defects
or other reproductive harm.
CAUTION: Installation of WILKINS Model 48 Gate Valves must be performed by qualied, licensed
personnel.
1. Cycle valve open and closed to ensure proper operation. Check that valve end connections
are clean. Fully close valve prior to installation. NOTE: For OS&Y valves, a small amount
of packing rubber may exit the valve via the stem during initial operations. This is normal
and does not affect valve performance. If stem leakage occurs, lightly tighten bronze gland
nuts evenly until leakage stops.
2. Install valve per proper methods according to end connection type.
3. If used in buried service, a valve box or vault should be provided for each valve.
4. Ensure all bolts are sufciently tight prior to pressurization.
5. Once pressurized, open valve and thoroughly ush line to remove debris.
6. Inspect valve for external leaks. If a leak is detected, see TROUBLESHOOTING section.
7. Fully close valve and listen for leaks past the wedge. If a leak is detected, see TROUBLE
SHOOTING section.
8. Fully open valve. WILKINS Model 48 Gate Valve is now in service.
