The GA Figure 220 Swing Check Valve is designed for wastewater and clean water systems, providing dependable backflow prevention in pump discharge lines. Its adjustable counterweight assisted closure ensures smooth opening at pump start and rapid, quiet closure at pump shutdown, effectively reducing water hammer and pipeline stress.

Built to AWWA C508 standards, this valve combines rugged construction with customizable options to suit demanding pump station environments. The design allows full flow area with minimal headloss, lowering pumping costs. A replaceable rubber disc seat ensures tight sealing under both low and high pressures, while the lever and weight assembly can be field‑converted for right‑hand or left‑hand operation, and for horizontal or vertical installation.

With corrosion‑resistant materials and epoxy coating, the GA Figure 220 is ideal for municipal waterworks, sewage treatment plants, and industrial pumping systems requiring reliable check valve performance.
