Operate the valve from full open to full closed to assure operability.2. Check flange bolting, actuator mounts and hangers 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 relatedequipment for looseness and correct as needed.5. If not in use, exercise the butterfly valve (full open and close) at least once a month.Safety PrecautionsBefore removing the valve from the line or loosening any bolts, it is important to verify the following conditions:. Be sure the line is depressurized and drained.. Be sure of the pipeline media. Proper care should be taken for protection against toxic and/or flammable fluids.3. Never remove the valve without an Operator (Manual or Automatic) already attached to the valve shaft.. Never remove the Operator from the valve while the valve is in the pipeline under pressure.5. Always be sure that the disc is cracked approximately 5° off of the closed position before removing the valve.Storage of Butterﬂ y Valve Assemblies Assemblies must be stored indoors, protected from the elements. Materials received on job sites that have long installation lead timesshould receive extra protection from construction damage. Valve faces must be protected from abrasion, cutting and nicking, as this will damage the face and may cause flange area leaks. Electric actuators cannot be stored in wet, damp or caustic areas. Do not store construction material on top of valve assemblies.L-Series Butterﬂ y ValvesInstruction ManualValve Installation ProcedurePosition the connecting pipe ﬂanges in the line to insure proper alignmentprior to valve installation. Spread the pipe ﬂanges apart enough to allow the valve body to be located between the ﬂ anges without actually contacting the ﬂange surfaces. Exercise particular care in handling the valve so as to prevent possible damage to the disc or seat faces.ote: Actuator must be mounted at or above pipe center line for all actuator types.1.For Lug style valves:a. Place the valve between the ﬂ anges.b. Install all bolts between the valve and the mating ﬂanges. Hand tightenbolts as necessary.2.Before completing the tightening of any bolts, the valve should be centered between the ﬂ anges and then carefully opened and closed toinsure free, unobstructed disc movement.3.Using the sequence, tighten the ﬂ ange bolts evenly to assure uniform compression. In assembling ﬂange joints, the resilient seating surfaceshall be uniformly compressed. 4.If an actuator is to be operated, electricity should be connected to the unit in accordance with the local electrical codes.5.Cycle the valve to the fully open position, then back to the fully closed position, checking the actuator travel stop settings for proper disc alignment. The valve should be operated to assure that no binding is taking place. If no power is available, use the manual handwheel.6.The valve is now ready for operation.Max Torque for BoltsValve SizeBolt SizeMax Torque [ft-lbs]8”3/4-10”1210”-12”7/8-9”20014325678143256789101112D6..WL0/16 - Subject to change. © Belimo Aircontrols (USA), Inc.71933-00001.B RevNext >
