APCO CAC-8000 Automatic Control Check Valve

Description

APCO CAC-8000 Automatic control check valves are multi-purpose valve, offering the Engineer a new

approach to pump discharge control. These valves combine the functions of flow control, check valve,

shut-off valve and reverse flow in a single unit. Available in a wide range of materials and sizes, APCO

CAC-8000 Automatic Control Check Valves are ideally suited for automatically controlled water

pumping stations. Design and operation is simple and understandable. Any maintenance required can

be handled by Municipal operating personnel – including – eventual seat replacement and the valve

need not be removed from the line.

APCO CAC-8000 Automatic Control Check Valves are more efficient than valves of conventional

design because of their multi-purpose functions. As a result, system design is simplified. Also, the full

flow Globe body compensates for the area occupied by the disc, greatly minimizing the head loss thru

the flow section of the valve.

APCO CAC-8000 Automatic Control Check Valves save power costs due to the smooth flow area and

valuable space in the Pump House due to their multi-purpose functions.

Lifting the valve improperly may damage it. Do not fasten lifting devices to the actuator, disc or through

the seat opening in the body. Lift the valve with slings, chains or cables fastened around the valve

body, or fastened to bolts or rods through bolt holes in the flanges.

The use of high quality materials of construction makes this valve practically maintenance free. A

periodic inspection and possible greasing of the gearing inside the box, perhaps once a year, is all that

is needed to keep the mechanism in good operating condition. Removing the cover (#30) will provide

access to all the internal moving parts of the gear box. Additionally the reservoirs should be checked

for correct oil levels and air pressure and the various piping around the valve inspected for oil leaks.

Valves with fusion/powder coated exterior paint require flat washers to be installed

under the flange nuts when installing the valve to the pipeline flange to prevent the

paint from cracking or chipping.
