User manual WA KATES MODEL L016 FLOW RATE CONTROLLER

[. . . ] All controllers are constructed substantially, but pipe supports should be located so that the controller is not subject to mechanical load due to piping, or to the 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 of operation. The preferred axis of the controller is vertical, with the bonnet up. INLET IS AT SIDE and outlet connection is at bottom. [. . . ] NOTE: Normally it is not necessary to remove the valve tube to clean it sufficiently. If it must be removed, follow instructions below "TO REMOVE VALVE TUBE". Thoroughly clean all parts that have been removed from the controller by immersing them in a suitable solvent. Clean and flush inside of flow controller body and the valve tube with the solvent, and drain. All surfaces, especially the metering orifice, the valve tube and integral valve ports, must 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. Replace orifice cylinder, and tighten clamp screws; replace the spring, impeller, and valve sleeve assembly on the valve sleeve. Make sure that the valve sleeve will slide freely on the valve tube with no sticking. Replace orifice sleeve, and make sure that the slot faces the inlet of the body. Install a new body O-ring, then lower the bonnet slowly making sure that the scored line is in line with the scored line of the body, at the same time turning the flow rate setting handle until the key on the end of the adjuster shaft fits into the slots in the orifice sleeve, and the shoulder on the lower face of the bonnet fits into the body. When properly assembled, bonnet will seat squarely on the body all the way around. (See figure 1) See that the pointer is in front where set point can be read. Replace and tighten the bonnet bolts (300 ft. lb of torque required). Place controller in service as specified under steps 2-7, "START UP PROCEDURE". TO REMOVE VALVE TUBE 1. If the valve tube must be removed, for cleaning or replacement, first remove all other internal parts of the controller. (Steps 1-7 above) Remove the valve tube screws, lift out the valve tube, and clean with solvent. Before replacing the valve tube, be sure that it is CLEAN. Also be sure that the counter-bore at the bottom of the body is CLEAN, as it forms a seat for the valve tube. Install valve tube, replace valve tube screws, and tighten them securely. Reassemble controller according to steps 9-12 above. TO REPLACE ADJUSTER SHAFT PACKING: 1. The only packing required is between the adjuster shaft and the bonnet. [. . . ] THIS WASHER SHOULD HAVE A TIGHT FIT AROUND THE SHAFT.
