User manual WA KATES FM50

[. . . ] OPERATION OF A KATES ADJUSTABLE FLOW RATE CONTROLLER THAT IS SUPPLIED BY A POSITIVE DISPLACEMENT PUMP, WILL BE SATISFACTORY ONLY IF A PRESSURE-RELIEVING VALVE IS CONNECTED BETWEEN THE PUMP AND THE CONTROLLER. THIS IS TO BYPASS EXCESS FLUID BACK TO THE FLUID SOURCE, OR TO THE INTAKE OF THE PUMP. INSTALLATION 1. The Kates flow controller is shipped fully assembled, ready for operation, with all parts in place. [. . . ] 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. It is necessary to remove the controller from the line to clean. If installation includes proper shutoff and bypass valves, operate these and take the controller out of line. Arrange a clean area where internal trim parts can be placed and kept free of lint or grit. Pull out the valve tube, valve sleeve and spring and put it in the clean area. Remove the snap ring from the adjuster needle bore. Notice: Never perform this operation while the controller is pressurized. 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 closely fitted parts, it is VERY IMPORTANT that all parts and surfaces, including valve ports, be COMPLETELY CLEAN. Any dirt, sediment, coating or gummy residue must be completely removed. Wipe all parts and surfaces dry with a clean, lint-free cloth. CAUTION: in all cleaning operations, be very careful not to scratch, nick or mark any surfaces or edges. 14. The standard o-ring material for the Kates flow controller is PFTE, which has no elastic memory. It may be necessary to install new o-rings whenever the controller is disassembled. Holding the valve sleeve with the open end up, install the spring in the seat at the bottom of the valve sleeve bore. Still holding the valve sleeve with open end up, insert the valve tube in the valve sleeve bore.
