1 ULLTIN 00/579 JUN 2016 PO S-00/00 SING K LS PO S Swing heck s are recommended for clean and dirty services such as ater, Sewage or Industrial applications. S-00/00 Swing heck s are a heavily constructed, full waterway flow area, premium design with multiple features and options. The S-00/00 is designed to handle higher flow rates, pressures and withstand shock. vailable in sizes 2-66" (50-10mm), the S-00/00 Swing heck s are available with crylonitrile- utadiene (NR), Terpolymer of thylene, Propylene and iene (PM) or luoro Rubber (KM) resilient disc seats, or cast aluminum bronze or stainless steel metal seats for durability. The body seat is long-wearing centrifugally cast aluminum bronze or Type 316 stainless steel. ody seats are available with a NR, PM or KM resilient seal. igh Strength Shaft One-piece shafts are constructed of Type 303 or 17-4 P stainless steel for high strength. Throughshaft design, with an integral retainer, prevents axial shaft movement. ull aterway low rea The valves feature a full waterway flow-through area and low head loss. The pivot point of the disc is located outside the port opening, allowing the entire disc to lift clear of the flow area. This is particularly important in sewage, slurries or other dirty service applications. ouble levis, Self-ligning isc The double clevis design securely connects the disc to the disc arm in two places. The double clevis hinge assures self-leveling and even load distribution upon closing, minimizing seat wear. The full open disc stop can be independently adjusted. The disc arm is ductile iron for high strength. Internals Removable ithout Removing from the Line Top entry design allows all internal parts, including the body seat, to be easily replaced in the field by removing the cover. The seat ring is field replaceable without the use of special tools.

2 losure ontrol evices ir ushion Side Mounted ylinder () or ree Open, ast lose applications, the air cushioned check valve utilizes a totally enclosed cushion cylinder externally mounted to the side of the main valve body. heavy outside lever, positively clamped to an extra-large diameter pivot shaft, forces the disc to close immediately upon pump shut down and before reverse flow takes place. The weighted lever drives the piston into the cushion chamber, 30 compressing the trapped air and creating a cushion during valve closure. ast losing ith ushion t Shut-Off Principle of Operation 1. ischarge velocity head from the pump against the disc (10) opens the disc and raises the weighted lever () outside of the valve upward. t the same time, the piston inside the cushion cylinder (20) is pulled upward, drawing free air into the cushion cylinder through the one-way control check valve (30). 2. hen reverse flow occurs against the backside of the disc (10), pressure forces the disc toward the shut-off position against the seat (5) at the same time forcing the cushion cylinder downward. Moving downward, the piston compresses the air in the cushion cylinder because the air cannot readily escape through the one-way control check valve. y restricting the air escape through the adjustable control check (30) air cushioned closing is accomplished. 3. ir cushioning is field adjustable by adjusting the flow control valve (30) for increased or decreased cushioning, or moving the weights on the pivot shaft for more or less rapid disc closure or Sizes 2-6" ( mm) See pages 9 and 10 for lever and weight and lever and spring closure control devices ezurik, Inc.

3 losure ontrol evices Oil ontrolled, Side Mounted ylinder (O) or ree Open, Slow lose applications, S-00 Swing heck s are available with an Oil ontrolled, Side Mounted ylinder closure control device. The totally enclosed oil cylinder is protected from the elements. Three-stage closure on valves 6-20" ( mm) minimizes damaging water hammer. Principle of Operation 1. ischarge velocity head from the pump causes the disc (10) to open and raises the outside weighted lever (). xcept for frictional resistance, the disc is free opening. 2. Three-stage closing is achieved by the oil dashpot/ timing valve system which minimizes damaging water hammer. ach stage is independently adjustable. a. The initial stage of closure is provided by the timing valve (45). The timing valve allows very fast closure of the disc from full open to any degree of closure. This feature greatly reduces the volume of backflow and flow reversal that occurs with on valves with only two stages of closure. Timing not supplied on sizes 2-4" (50-100mm) b. The second stage of closure is provided by the low ontrol (30) that varies speed toward final closure. c. The final stage of closure is provided by Timing internal adjustment of the cylinder (20) that controls variable speed closure to shut-off. d. dditional disc closing adjustments can be made by moving the weight on the pivot shaft.

4 losure ontrol evices Oil ontrolled, ottom Mounted uffer (M) ottom Mounted uffers have been used successfully for decades to reduce slamming of the valve disc and resultant water hammer. or ree Open, ontrolled lose applications, S-00 Swing heck s sizes 8-66" (200-10mm) are available with an Oil ontrolled, ottom Mounted uffer closure control device. Principle of Operation 1. The unique buffer arrangement allows the valve disc (10) to open fully without interference and to close freely for approximately 90% of its stroke. 2. fter the disc is 90% closed, the disc comes in contact with the buffer rod (33). The oil hydraulic buffer makes contact with the disc and controls closure during the final 10% of the stroke. 3. The flow control valve (41) on the cylinder (39) easily adjusts closing time to suit flow conditions reducing slam, water hammer and pressure surges. The color-coded micrometer type control valve adjusts the final closure, and has a locking set screw that is used to secure the final setting. ottom Mounted uffers are recommended for larger sized valves and for vertical upward flow installations. They are also recommended where instantaneous flow reversal caused by a hydro pneumatic surge tank or open line discharge is so fast that a free closing check valve cannot shut prior to reverse flow, and therefore slams. rain Opening Note: ashing ction utomatically leans the uffer rea 4
