APCO CVS-6000/6000A SWING CHECK VALVES

APCO CVS Swing Check Valves are recommended for clean and dirty services such as Water, Sewage or Industrial applications. CVS-6000/6000A Swing Check Valves are a heavily constructed, full waterway flow area, premium design with multiple features and options. The CVS-6000/6000A is designed to handle higher flow rates, pressures and withstand shock.

Available in sizes 2-66" (50-1700mm), the CVS-6000/6000A Swing Check Valves are available with Acrylonitrile-Butadiene (NBR), Terpolymer of Ethylene, Propylene and A Diene (EPDM) or Fluoro Rubber (FKM) 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. Body seats are available with a NBR, EPDM or FKM resilient seal.

High Strength ShaftOne-piece shafts are constructed of Type 303 or 17-4 PH stainless steel for high strength. Through-shaft design, with an integral retainer, prevents axial shaft movement.

Full Waterway Flow AreaThe 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.

Double Clevis, Self-Aligning DiscThe 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 Without Removing Valve from the LineTop 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.

Closure Control DevicesAir Cushion Side Mounted Cylinder (AC)For Free Open, Fast Close applications, the air cushioned check valve utilizes a totally enclosed

cushion cylinder externally mounted to the side of the main valve body. A 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, compressing the trapped air and creating a cushion during valve closure.

Principle of Operation1. Discharge velocity head from the pump

against the disc (10) opens the disc and raises the weighted lever (29) outside of the valve upward. At 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. When 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. By restricting the air escape through the adjustable control check (30) air cushioned closing is accomplished.

3. Air 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.

See pages 9 and 10 for lever and weight and lever and spring closure control devices.

Principle of Operation1. Discharge velocity head from the pump causes

the disc (10) to open and raises the outside weighted lever (29). Except 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. Each 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.

b. The second stage of closure is provided by the Flow Control Valve (30) that varies speed toward final closure.

c. The final stage of closure is provided by internal adjustment of the cylinder (20) that controls variable speed closure to shut-off.

d. Additional disc closing adjustments can be made by moving the weight on the pivot shaft.

Closure Control DevicesOil Controlled, Side Mounted Cylinder (OC)For Free Open, Slow Close applications, CVS-6000 Swing Check Valves are available with an Oil Controlled, Side Mounted Cylinder closure control device. The totally enclosed oil cylinder is protected from the elements. Three-stage closure on valves 6-20" (150-500mm) minimizes damaging water hammer.

Closure Control DevicesOil Controlled, Bottom Mounted Buffer (BMB)Bottom Mounted Buffers have been used successfully for decades to reduce slamming of the valve disc and resultant water hammer. For Free Open, Controlled Close applications, CVS-6000 Swing Check Valves sizes 8-66" (200-1700mm) are available with an Oil Controlled, Bottom Mounted Buffer closure control device.

Bottom Mounted Buffers 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.

4

Principle of Operation1. 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. After 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.

Closure Control DevicesConvertible Swing Check Valves (CLW & CLS)If hydraulic conditions exceed those anticipated, CVS Convertible Swing Check Valves can be converted in the field to closure control devices that reduce moderate or severe slam. For moderate slam, CVS-Convertible Lever & Spring Valves (CLS) or CVS-CLW Convertible Lever & Weight Valves (CLW) can be converted to an Air Cushion Side Mounted Cylinder. For severe slam, CVS-Convertible valves can be retrofitted in the field to Oil Controlled Side Mounted Cylinder or Bottom Mounted Buffer closure control devices.
