Check valves are designed to close quickly and automatically with positive shut off in either horizontal or vertical (flow up) pipe runs. Inherently, check valves have a low pressure drop and are best suitable for velocity applications. Closure design allows our swing check valve to close completely even and remain closed with no flow when installed in a horizontal pipe run.
The body is full ported and spherical in form. The design utilizes large radiuses which allow for the stresses, flow resistance and turbulence to be kept to a minimum. Seat rings are designed to greatly reduce and/or prevent any turbulence and avoid damages due to corrosion.
» Wafer, Lug, Flange options
» Retainer less design eliminates fugitive Emissions. Is firesafe by design
» Discs open 85° to ensure a low pressure drop
» Positive sealing under most operating conditions. The valve closes before the flow reverses at zero velocity.
» Dual plate, non-slam, single disc, hub end, nozzle check valve options
» Wafer Check Valves can be installed in the horizontal and vertical up positions.
