HAMMOND VALVE INSTALLATION OPERATION AND MAINTENANCE MANUAL FOR BRONZE VALVES CAST IRON VALVES CAST STEEL VALVES SILENT CHECK VALVES THREADED END TWO PIECE BALL VALVES SOLDER END TWO PIECE BALL VALVES LUG BUTTERFLY VALVES WAFER BUTTERFLY VALVES 2003 BRONZE GATE, GLOBE AND CHECK VALVE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS INSTALLATION 1) Thoroughly clean and prepare the piping system before valve installation. 2) Remove the valve end caps if present, and inspect the valve ports and seating surfaces for cleanliness just prior to installation. 3) Support the valve to prevent unnecessary stresses induced by connecting pipe. 4) Be sure the rating of the valve is compatible with the intended service conditions. 5) Operate the valve from the full open to closed position. 6) Verify the tightness of the packing nut after installation. NOTE:Make sure check valves are oriented properly for flow and gravity effect, and that they are sufficiently distant from pump outlets or other turbulence inducing devices. OPERATION 1) Gate and globe valves are manually operated. To open, turn the handle in a counterclockwise direction. To close, turn the handle in a clockwise direction. 2) Check valves are automatic. INSPECTION & MAINTENANCE 1) Periodic inspection and preventative maintenance is not required other than adjustment of stem packing, and cycling of the valve from open to closed position. 2) If a valve develops a packing leak, adjust the packing nut to increase the pressure on the stem packing. The packing nut should be turned in a clockwise direction approximately ¼ turn, or until the leakage stops. It is not recommended that valves be repacked while under pressure. Remove system pressure before starting. 3) Whenever a new stem is installed, the packing should be changed also. REPAIR PARTS Under normal conditions, repair parts are not required. Parts that may be considered recommended spare parts are as follows: Gate Valves-handle, handle nut, packing, gland, packing nut. Globe Valves-handle, handle nut, packing, gland, packing nut, disc and seat. Check Valves-disc, holder and hinge assembly. When ordering parts, provide figure number, size, part needed and age of the valve.
