VAL-MATIC'S 3"-24" SERIES 2000 BUTTERFLY VALVE OPERATION, MAINTENANCE AND INSTALLATION INTRODUCTION DESCRIPTION OF OPERATION The Series 2000 Butterfly Valve has been designed to give years of trouble-free operation. This manual will provide you with the information to properly install and maintain the valve to ensure a long service life. The valve is a resilient seated, quarterturn valve capable of handling air, water, or other clean fluids.
PAGE 3
VALVE CONSTRUCTION The standard Series 2000 Butterfly Valve is constructed of rugged cast iron with a stainless steel shaft and resilient disc edge. See the specific Materials List submitted for the order if other than standard cast iron construction. The details of construction are illustrated in Figure 2. The body (1) is available with flanged or mechanical joint ends for connection to the pipeline. The body is equipped with a stainless steel seat (2).
PAGE 4
INSTALLATION AWWA Class 250B flanged valves can be mated with either ANSI Class 125# or ANSI Class 250# flanges depending on the specified flange drilling. Class 250B valves can be mated with flat-faced or raised-face flanges with full face or ring gaskets and with no bolting restrictions. The installation of the valve is important for its proper operation. Some general recommendations follow. Some specific piping problems are also shown in the figures to the right.

MECHANICAL JOINT BOLT TORQUES INSTALLATION (Cont'd) VALVE SIZE (in) In all installations, the valve and adjacent piping must be supported and aligned to prevent cantilevered stresses on the valve. Lower valve into line using slings or chains around the valve body. Lubricate the flange bolts or studs and insert them around the flange. Lightly turn bolts until gaps are eliminated.
PAGE 6
LEVER OPERATED VALVES: 8" and smaller valves may be equipped with a top-mounted lever for direct quarter-turn operation. To open the valve, slowly rotate the lever 90° in the counter-clockwise CCW direction. disc seal in the body seat. No field adjustment is necessary. VALVE SEAT ADJUSTMENT: If the valve is found to leak in service, the rubber seat can be adjusted. With the valve in the closed position, tighten the three seat bolts in the area of the leak 1/4 turn at a time until the leak stops.
PAGE 7
PACKING REPLACEMENT: To replace the packing, it is recommended that the line be drained and the actuator removed. The valve can remain in the line. MAINTENANCE The Series 2000 Butterfly Valve requires no scheduled lubrication or maintenance other than regular exercising. The exercising is achieved by fully opening and closing the valve to verify smooth operation.
PAGE 8
MAINTENANCE (Cont'd) WORM GEAR ACTUATOR MAINTENANCE: A typical worm gear actuator is shown in Figure 10 and consists of a worm (3) mounted on an input shaft (9). The worm engages a segment gear (2). When the worm is turned, it drives the segment gear through 90° of rotation. The rotation of the segment gear is displayed by the top indicator (5). The gears are lubricated with EP2 grease in a cast iron housing (1).
PAGE 9
MAINTENANCE (Cont'd) TRAVELING NUT ACTUATOR MAINTENANCE: A typical traveling nut actuator is shown in Figure 11 and consists of a threaded nut (12) which travels back and forth on a threaded stem (14). The stem is lubricated with EP2 grease in a cast iron housing (1). The nut, in turn, drives a slotted lever (4) through 90 degrees of travel. The lever (4) drives the valve shaft with a square key. The rotation of the shaft is displayed by the top indicator (19).

TROUBLESHOOTING DISASSEMBLY Several problems and solutions are presented below to assist you in troubleshooting the valve assembly in an efficient manner. Disassembly may be required to repair the valve. Work on the valve should be performed by a skilled mechanic with proper tools and a power hoist for large valves. The valve must be removed from the pipeline for disassembly. The actuator can be removed with the valve in the line (the line must be drained) or after the valve is removed from the line.
PAGE 11
REASSEMBLY SEAT REPLACEMENT All parts must be cleaned and gasket surfaces should be cleaned with a stiff wire brush in the direction of the serrations or machine marks. Worn parts, gaskets and seals should be replaced during reassembly. Bolts should be lubricated and torqued per Table 6 during reassembly. If the seat is badly worn or damaged, gain access to valve interior and remove existing cap screws, seat retaining ring, and seat.
