User manual WA KATES 5050

[. . . ] The Kates Controller is constructed substantially, but pipe supports should be located so that the controller is not subject to mechanical load due to piping, or expansion or contraction of piping. The controller should be installed at a point in the pipe where it will be completely filled with liquid under all conditions or operation. On threaded connections, apply pipe thread compound sparingly to male threads only so that surplus will not get inside the controller and cause "sticking" or prevent operation. START UP PRODEDURE 1. The pointer on the stainless steel nameplate should be at front, readily visible to operator. [. . . ] During this warming up period, the controller may be somewhat sluggish in action. If desired, this warming up period may be eliminated by the use of a heating coil or jacket. During the first few days of operation, gasketed joints should be observed and tightened if necessary. BLT 303 - 01 SERVICE INSTRUCTIONS The Kates Flow Rate Controller has only one moving element, and is designed so that there are no complex linkages, delicate bearings, or any failure-prone components. Therefore, occasional cleaning may be the only servicing the controller will require. CAUTION: MAKE SURE THAT THE CONTROLLER IS RELIEVED OF PRESSURE BEFORE ATTEMPTING TO SERVICE OR CLEAN. TO CLEAN CONTROLLER CAUTION: in all cleaning operations, be very careful not to scratch, nick or mark any surfaces or edges. If installation includes proper shutoff and bypass valves, operate these and take controller off stream or control. Arrange a clean area where internal trim parts can be placed and kept free of lint or grit. Remove bonnet bolts, lift bonnet assembly straight up, and set it in the clean area. Remove the orifice cylinder clamp screws, lift out the orifice cylinder and put it in the clean area. Thoroughly clean all the parts which have been removed from the controller by immersing them in a suitable solvent. Thoroughly clean and flush inside of controller body with the solvent, and drain. Because of the small size of orifice opening and the closely fitted parts, it is VERY IMPORTANT that all parts and surfaces, including the orifice opening and valve ports, be COMPLETELY CLEAN. Any dirt, sediment, coating or gummy residue must be completely removed. CAUTION: in all cleaning operations, be very careful not to scratch, nick or mark any surfaces or edges. Replace orifice cylinder insuring that it seats firmly on the valve sleeve. See that the orifice sleeve is clean and that the orifice slot is clean and open. Place it on the orifice cylinder, check for free rotation, and see that it does not ride on top of the stop pin. When replacing bonnet, revolve dial and knob assembly and thus fit the cross bar into the slots in the upper end of the orifice sleeve. Place controller in service as specified under steps 2-7, "TO PLACE CONTROLLER IN SERVICE". TO REPLACE ADJUSTER SHAFT SEAL: 1. The only packing required is between the adjuster shaft and the bonnet. [. . . ] If flats on shaft do not fit into those in knob, turn knob slightly, then tap or press it down into place. Replace regulator bonnet, and put the regulator "on stream" by following Steps 2-7 listed under the heading "START UP PROCEDURE".
