Heavy Duty AWWA C508
CHECK VALVES DESCRIPTION,
OPERATION AND HEADLOSS
Description
Pump Check Operation
Golden Anderson© Heavy Duty Swing Check Valves provide longterm, dependable service in water, wastewater and raw sewage
applications. These valves are ruggedly designed to withstand the
rigors and frequent operation of pump station use, opening freely
when the pump starts and closing quickly and quietly upon pump
shutdown to prevent reverse flow. The Golden Anderson© Heavy Duty
Swing Check Valves meet or exceed the design, materials of construction and testing requirements of AWWA C508, are rubber-seated
for zero leakage and are available with either outside lever and weight
or lever and spring for installation in horizontal or vertical pipes.
At pump start, the valve disc swings away from the seat in
proportion to the fluid’s forward flow velocity, lifting the counterweight or extending the external spring as it does. The design of
the Golden Anderson™ heavy duty check valve provides a full
flow area when the disc has swung away from the seat by as
little as 22½ degrees but can open as much as 60 degrees if the
fluid velocity is sufficient.
Single- and double-increasing heavy-duty swing check valves are
ideal for small pump stations and sewage lift stations. These check
valves eliminate the increaser fitting and can shrink the pump
station footprint saving space and reducing installation cost.

At pump shutdown, the force of the heavy counterweight or
extended spring “pulls” the valve closed through the decreasing
forward fluid velocity during pump coastdown so the valve is fully
seated before fluid reversal occurs, precluding slam and bang.
The heavy closure devices needed to ensure quiet closure require
over-sized hinge shaft and bearings to withstand the forces
produced by rapid closure. Figure 1 compares the significantly
larger diameter shaft of the Golden Anderson™ heavy duty check
valve to that of a “standard” swing check. The standard valve’s
small shaft diameters could not accommodate the heavy closure
devices needed for quiet operation thus increasing the likelihood
of slam and bang.
