CAUTION: Installation of ZURN WILKINS Model 48 Gate Valves must be performed by qualified,
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 sufficiently tight prior to pressurization.
5. Once pressurized, open valve and thoroughly flush 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
TROUBLESHOOTING section.
8. Fully open valve. ZURN WILKINS Model 48 Gate Valve is now in service.
