In the simplest terms, check valves open to allow forward flow and close to prevent reverse flow. One of the most common, yet critical, uses of a check valve is on the discharge of a pump to prevent reverse flow when the pump is not operating. Pump station check valves are often subjected to rigorous operating conditions and may be required to operate without slam and waterhammer and to afford low head loss.
As a result, GA Industries offers a wide variety of standard check valves each ruggedly designed to accommodate the specialized needs of pump station use. From simple AWWA C508 swing check valves to sophisticated top mounted cylinder tilting disc check valves, there is a GA Industries check valve to suit most any water, wastewater or sewage pumping application.
In addition to check valves, GA Industries offers a full range of Pump Control Valves
for those pumping applications where conditions require the check valve to not only close to prevent reverse flow but also to control the pressure surges associated with the starting and stopping of pumps.
