3 The following careshould be taken when storing sure the Valve end connection coversremain in place during the Valve does not have an operator alreadyinstalled and the Valve will be stored outside,the open stem extension or the stem adaptershould be covered to avoid water of the most trusted valves in the petroleumindustry,Cooper Cameron valves Welded body BallValve combines the strength of forged componentswith a lightweight and compact spherical Welded body ball valves satisfy ANSI 150through 2500 (PN 20 through PN 420) and API 2000through 5000 standards. Made of forged steel toassure uniform fine grain structure and toughness,they may be specified in sizes from 2 to 56 (DN 50 to DN 1400). Engineered for heavy-dutyservice, and minimal maintenance, the CameronWelded body ball Valve is commonly selected for anumber of applications.

4 The distinctive design ofthe Cameron Welded body ball Valve gives itmaximum strength and minimum weight as wellas maximum resistance both to pipeline pressureand stresses. The compact, spherical design alsoeliminates body flanges, thus reducing overall sizeand leak long-term storage is required, the valveshould be conditioned using a corrosioninhibitor and end connection covers. Followthe guidelines found in Cameron EngineeringBulletin 476B for long term storage.

7 Thiswill allow any pipeline debris to be flushedthrough the Valve bore and out of the the piping system has been purged ofdebris and the system has been filled com-pletely with the test fluid, the ball valveshould be placed in the partially open position(approximately 10o from the fully open posi-tion). This allows test fluid into the body cavityof the Valve is now ready to be pressure completion of hydrostatic testing, thevalve should be returned to the fully openposition before removing the test fluid fromthe piping system. The test fluid in the bodycavity can be drained through the body drainport located on the lower portion of the the Valve and piping system have beenpigged and customer product is injected intothe piping system, the Valve should be movedto the partially open position (approximately10o from the fully open position).

8 Any remain-ing test fluid trapped in the Valve body cavitycan then be vented through the body bleedplug, located on the lower portion of the valvebody. If the Valve has been fitted with a stemextension, the vent fitting will be locatedbelow the mounting flange on top of the body bleed fitting will forcetrapped test fluid out of the body cavity. Keepthe bleed plug open until all fluids have beenexhausted through the body bleed the Valve body bleed fitting and returnthe Valve to the fully open position or therequired operating Valve seat pockets should be filled with anapproved Valve flush product to displace anytest fluid.
