If outdoor storage is necessary, support valves off the ground or pavement in watertight <br /> enclosures. ' <br /> C. Handling: Use a sling to handle valves whose size requires handling by crane or lift. Rig valves to avoid damage to <br /> exposed valve parts. Do not use handwheels and stems as lifting or rigging points. <br /> t <br /> PART 2: PRODUCTS <br /> 2.01 MANUFACTURERS <br /> A.
