Designed using FEA optimization, the PT utilizes a one-piece rolled worm/shaft an economical yet highly efficient process. Care was taken to eliminate unnecessary parts and standardize on parts used across the nine torque ranges. Available with both ductile iron and bronze alloy worm gears (AWWA and modulating applications), the PT can be installed in the harshest of environments to -50 C where necessary. Whether purchased for manual applications or coupled with Limitorque electric actuators, the PT will provide years of trouble-free and reliable operation. 4

7 1 Introduction 1.1 Purpose This installation and maintenance manual explains how to install and maintain the PT operator. Information on installation, disassembly, reassembly, lubrication, and spare parts is provided. 1.2 User Safety Safety notices in this manual detail precautions the user must take to reduce the risk of personal injury and damage to the equipment. The user must read and be familiar with these instructions before attempting installation, operation, or maintenance. Failure to observe these precautions could result in serious bodily injury, damage to the equipment, voiding of the warranty, or operational difficulty. Safety notices are presented in this manual in three forms: c WARNING: Refers to personal safety. Alerts the user to potential danger. Failure to follow warning notices could result in personal injury or death. a CAUTION: Directs the user s attention to general precautions that, if not followed, could result in personal injury and/or equipment damage. NOTE: Highlights information critical to the user s understanding of the operator s installation and operation. 7

9 2 Inspection, Installation, and Mounting Procedures 2.1 Initial Inspection and Storage Instructions c WARNING: Read this installation and maintenance manual carefully and completely before attempting to store the operator. If an electric operator is attached to the PT manual operator, be aware of the electrical hazards. Consult the electric operator installation and maintenance manual for guidance. 2.2 Inspection and Recording Upon receipt of the operator, inspect the condition of the equipment, and record nameplate information. 1. Carefully remove operator from shipping carton or skid. Thoroughly examine the equipment for any physical damage that may have occurred during shipment. If damaged, immediately report the damage to the transport company. 2. A nameplate is attached to each operator with the following information: Operator size Operator ratio Flowserve Order Number Operator serial number Record this information for future reference, i.e., ordering parts, obtaining further information. 9

10 2.3 Storage Procedure NOTE: The following is the recommended storage procedure to retain maximum product integrity during storage. Failure to comply with recommended procedure will void the warranty. Storage (less than 1 year preferred) Store operators on wooden skids to protect the machined mounting flange. Place the wooden skids containing the operators in a clean, dry, protected warehouse. If the operators must be stored outside, they must be covered in polyethylene protection with silica gel crystals to absorb moisture. If an electric operator is attached to the PT, refer to the storage procedures in its respective manual for appropriate storage procedures. Rotate input shafts every three months to mix the lubricant. 2.4 General Mounting Instructions a CAUTION: To avoid the potential for disengaging the worm gear segment, ensure that the pointer cap pointer is oriented to the mid-point of the 90 valve travel. Full stroke rotation of the pointer should not move past the corresponding Open or Close ID marks on the housing cover. 1. Place valve in full closed position. 2. Remove pointer cap from PT operator. Refer to Section 5.1 for removal/replacement instructions for the pointer cap. 3. PT12/14/32/C32/120/150 Slide splined adapter on valve shaft and insert key, or utilize a setscrew to eliminate movement of splined adapter on the valve shaft. 4. Mount operator on valve and bolt securely. Confirm operator stop alignment before engaging splines. 5. PTA32/65 Remove the splined adapter from the PT and mount the PT to the valve. Align the valve shaft with the bore and key of the splined adapter. Using either the PT or electric actuator handwheel, rotate the PT drive sleeve to align the drive sleeve s splines with the splined adapter. Slide the splined adapter down onto the valve stem and into the drive sleeve of the PT. 6. PT250 through 1000 Torque nuts are bolted into place from the top of the PT. Remove the torque nut and align the valve drive stem with the bore and key of the torque nut. Slide the torque nut onto the valve stem. Using either the PT or electric actuator handwheel, rotate the PT drive sleeve to align the drive sleeve s threaded holes with the torque nut s through holes. Bolt the torque nut into position. Preload property class 8.8 fasteners, securing torque nut as follows at installation. (Preload is not set at factory.) 10 Unit Size ft-lb N m PT PT PT1000 1,200 1,620 Fasteners that are stainless steel or other than property class 8.8 require different preload torque than listed above. Consult factory.

11 7. Turn PT operator input shaft to full closed position. The stops are preset for 90 travel. Be certain of correct direction of rotation. 8. For standard stop setting instructions for the PT18 through 150, see Section 5.3, Adjustment, Removal and Replacement of Stops Screws. 9. For standard stop setting instructions for the PT250 through 1000, see Section 6.3, Adjustment, Removal and Replacement of Adjustable Stops. 11

13 3 Lubrication The Limitorque PT operators are shipped with Conoco Dynalife-L-EP0, Lithium base grease in the operator. This lubricant is suitable for a temperature range of 0 F to 225 F (-18 C to 107 C). Alternative lubricants are: Triton ELL Lithium complex grease from -40 C to 88 C (-40 F to 191 F ) Troco EP-00 Calcium complex grease from -29 C to 121 C (-20 F to 250 F) (early shipments of PTs contain this grease) Mobil SHC632 synthetic oil from -30 C to 85 C (-22 F to 185 F) Standard options for arctic duty (-50 C/-58 F to 50 C) with Petro-Canada Traxon SYN75W90. The lubricant should be checked every 18 months for manual operators. a CAUTION: Do not add a different lubricant to a Limitorque operator unless it is of the same soap base as the existing lubricant or you have received the approval of the lubricant manufacturer. 13
