STORAGE 1.1 The seat, disc, stem and bushing of the butterfly valve should be coated with a silicone lubricant. 1.2 The disc should be opened (5º 7º) during transportation & storage. 1.3 Where applicable, the faces of each valve should be covered with cardboard, plywood or similar sturdy material to prevent damage to the seat face, disc edge or butterfly valve interior. 1.3 Valves should be stored indoors with face protectors intact. Storage temperature ideally should remain in a range from +40°F to 85°F. 1.4 When valves have been stored for more than 3 months, open and close the valves. Repeat for every 3 months of storage. 1.5 Store valves so that no heavy loads are applied to the bodies. 2.VALVE INSTALLATION 2.1 Make sure the pipeline and pipe flanges are clean. Any foreign material such as pipe scale, metal chips, welding slag, welding rods, etc. can obstruct disc movement or damage the valve. 2.2 Ensure that the entire rust preventive on the machined surface in the flow area is removed, before the valve is put in pipe-line. 2.3 Note the name plate details and arrow flow mark on valve body and install the valve in right orientation with respect to pressure gradient. Arrow on valve body should point from high pressure side to low pressure side of the pipeline. Recheck valve pressure rating adequacy with respect to operating pressure. 2.4 Align the piping and then spread the pipe flanges so that the valve body can be easily placed between the flanges without contacting the pipe flanges. 2.5 Insert the valve between the flanges taking care not to damage the seat faces. Always pick the valve up by locating holes or by using a nylon sling around the valve neck. IMPORTANT: Never pick the valve up by the actuator or operator as damage may occur. 2.6 Place the valve between the flanges, center it, and then span the valve body with all flange bolts. Do not tighten the bolts at this time. Carefully open the disc to the full open position, ensuring that the disc does not make contact with the pipe I.D. Systematically remove any jack bolts on flange spreaders and hand tighten the flange bolts. Very slowly close the valve disc to ensure disc edge clearance from the adjacent pipe flange I.D. 2.7 Operate the butterfly valve manually from full close to full open and full open to full close, with the operator hand wheel. Ensure that there is no undue resistance / friction in the operation. Ensure that the factory setting of Limiting Stopper Bolts in the Gear Box is not disturbed, for the respective limit positions. If so, adjust the same. 2.8 Before connecting valve & pipeline flanges, ensure that they do not have parallel, angular and radial gaps. While fitting the valve in pipeline, ensure that diagonally opposite bolts are simultaneously & uniformly tightened. 3.VALVE MAINTENANCE 1. Operate the valve from full open to full close to assure operability. 2. Check flange bolting for evidence of loosening and correct as needed. 3. Inspect the valve and surrounding area for previous or existing leakage at flange faces or shaft connections. 4. Check piping and/or wiring to actuators and related equipment for losseness and correct as needed. Possibilities Causes Remedies Valve opens only afew degrees andstops (Itwillnotopentothe full angle desired) Leakage between disc and valve seating Leakage between valve stem and packing Switch can’t be used freely 1.Improper installation .The valve is improperly aligned. 2.Mating pipe internal or other obstruction is interfering with disc. 3.Actuator not properly installed. 1.There is muddy sediments accumulated on seal surfaces. 2.Worn out or scored seal surface. 3.Close on the misplace. 1.Packing cap has not screwed on tightly. 2.Packing wears out. 3.The contact surface between valve stem and packing wear out. 1.Seal surface is deformed too heavily. 2.Failure of the actuator. 1.Loosen the flange bolts, realign the valve with flanges and retighten the flange bolts to correct torque per ANSI requirements. 2.Pipe does not meet standards and spacers may be required Any pipeline or disc obstruction must be removed. 3.Refer to actuator adjustment manual. 1.Clean muddy sediments. 2.Repair or replace seal surface . 3.Adjust the close position of the actuator 1.Tighten the nuts on the cap to get a uniform pressure between cap and packing. 2.Add suitable amount of packing. 3.Replace stem or repair the contact surface of valve stem. 1.Adjust the bolts on it. 2.Replace or repair it.
