Unless a commercial laboratory is used for inspec'\k-' tion, the manufacturer shall furnish all measuring and test equip- Jnent required to conduct the examination and tests specified herein. The quality control procedures specified in 4.4.1 shall provide for regular calibration of Instrumentation and test equipment In accord ance with the manufacturer's established standards and procedures. Water used as the test medium for hydrostatic seat leakage tests shall be clean and free of sediment. Additives with a potential for diminishing leakage by altering suchfluid properties as viscosity or surface tension shall not be used. Oil, grease, or other compounds shall not be applied to seating surfaces as a means of effecting a tighter seal. Valves shall be shell tested before the final coat of paint is applied. For seat tests, the valves shall be closed by handwheels normally furnished on the valve without wrenches or other auxiliary means for applying abnormal closure force. 4.5.1 Shell test. Each valve shall be subjected to the hydro static test pressure specified in 3,6. The pressure shall be applied with both ends blanked and the gate in the open position. The duration of the test shall be not less than 60 seco^s. Any leakage attributable to defective workmanship or castings shall be cause for rejection of the valve. Gas test pressure may bis used for the shell test in lieu of hydrostatic,pressure at the ,option of the supplier. Gas test pressures shall.be equal to the speci fied hydrostatic test pressures. w 4.5.2 Seat test. Each valve shall be subjected to a seat leak age test to verify compliance with 3.6. Tests shall be. conducted using air, gas, or water as the test medium. The test pressure specified in 3.6 shall be applied successively to each side of the closed gate with the opposite side open for inspection. As an alternate method for type II, double disk valves, the pressure may be applied inside the body or bonnet with the disks closed and both Bides open for inspection. If no leakage occurs within 30 seconds after the test pressure has been applied, the test may be discontinued. If measurable leakage occurs within the 30 second observation period, the test shall be continued for a length of. time sufficient to permit an accurate determination of the leakage rate. (For hydrostatic seat: tests, leakage per inch of nominal valve size exceeding two drops during the 30 second initial observation period shall be considered as sufficient measurable leakage for continuance of the tests). Any leakage exceeding the maximum permissible rates specified in 3.6 shall be cause for re jection of the valve unless corrective action to renew or recondicion seating surfaces is taken and the valve is satisfactorily retested. 1 12 s. ` <t NIBCO001369 WW-V-5SB - w ' V 4.5.3 Material tests.

PREPARATION FOR DELIVERY '5.1 Cleaning, preservation, packaging and packing. Valves shall be cleaned, preserved, packaged, and packed in accordance with the specified level(s) of MIL-V-3 (see 6.2). ^ 5.2 .Marking. (see 6.2). ,4 5.2.1 Civil agencies. Each unit package shall be marked to show the Federal stock number, nomenclature, and quantity. Each shipping con tainer shall be marked in accordance with Fed. Std. No. 123 and shall include the contract and purchase order number. ' 5.2.2 Military agencies. Marking shall be in accordance with MIL-V-3. 6. NOTES 6.1 Intended application. Gate valves are intended for installations where the valve will normally be^ fully opened or fully closed and where a minimum pressure drop is required. These valves are designed for free unobstructed flow and are not suitable fox throttling. Type I, solid, wedge di8k valves are suitable for steam service where double disks would tend to vibrate or chatter. Type II, double disk valves are suited especially for HOG service. Double disks with parallel seats are more readily refaced than wedge disks and tapered seats. Valves with outside screw and yokes are used to advantage in pipelines handling materials . which might be deleterious to stem threads, and where the rising stem serves to provide a required visual indication of the disk position. Valves with nonrising stems are suited for installations with low head- r^om for handwheel operation. This specification does not cover nut- operated gate valves such as used on buried water lines and which conform to the American Water Works Association standard AWWA C5Q0; Gate Valves for Ordinary Water Works Service. < 13 NIBCO001370 WW-V-58B ? 6,2 Ordering data.
