APCO AVV-1800/1800K Dual Body Combination Air Valve
with CSV Surge Check Valve
Description
The APCO Dual Body Combination Valve with Surge Check Valve consists of an Air/Vacuum Valve
piped (with a shut-off valve on the 4"-24" only) to an Air Release Valve and mounted on top of a Surge
Check Valve.
The AVV-1800 and AVV-1800K are the functionally the same. The AVV-1800 with Optional CSV Surge
Check ships fully assembled from the factory. The AVV-1800K with Optional CSV Surge Check ships
with the Air/Vacuum Valve assembled with the CSV, Air Release Valve, and piping kit. The customer will
pipe the Air Release Valve to the Air/Vacuum Valve.
The CSV Surge Check Valve is designed to eliminate critical shock conditions occurring in installations
where the operating conditions cause a regular air valve to slam closed. This slow closing feature
protects the Air/Vacuum valve and also prevents the Air/Vacuum valve from creating a surge in the
pipeline by slamming shut.
The Surge Check Valve should not be considered as relief for shock conditions which develop
elsewhere in the system. However, actual field tests prove the Surge Check Valve may protect the
Air/Vacuum Valve from damage by severe shut-off shock.
Handling and Storage
Lifting the valve improperly may damage it. Do not fasten lifting devices to piping or attached
components. 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.
If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary outside
storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.) is secured
around/over the valve to keep off rain and mud. Skid and set the assembly on a flat, solid, and well
drained surface for protection from ground moisture, runoff and pooled rain water.
AVV-1800K Assembly
Assembling the Combination Valve incorrectly or while not wearing appropriate Personal
Protective Equipment (PPE) can cause personal injury. In addition, when lifting, use
appropriate lifting hooks/straps to avoid personal injury.
Do not deflect the piping joints. While applying torque to tighten components, minimize
bending stresses in the piping kit components.
For the AVV-1800K, assemble the valves together as stated below:
1. Place the fully assembled AVV (Air/Vacuum Valve) on a flat surface.
2. Acquire piping kit shipped with the valves.
