SURESEAL Water Hammer Control Devices
SURESEAL Zero Velocity Valves and Air Cushion Valves very effectively prevent the water hammer or pressure surge in long distance large diameter cross country rising mains. The two valves complement each other to provide a complete solution for controlling both upsurges and down surges or vacuum. The Zero Velocity Valve prevents oscillation of water column after tripping of all pumps due to conditions such as power failure. And the Air Cushion Valve, by instantaneous vacuum breaking, controls the down surges or vacuum and by controlled release of air reduces the effect of secondary surges arising due to oscillation of water column.
