The ProFlex Style 790 low-headloss check valve from Proco Products provides rapid dispersion of head pressures and with its low cracking pressure, it prevents upstream flooding. The inline design allows the valve to be installed without having to do any modifications to existing structures or pre-install planning. The fold-away design of the inner sleeve allows for a near full port flow, allowing for quick drainage. It will allow for passive flow operation, making it the fit for combined sewer overflows, sanitary sewer overflows and outfalls. It is available in many elastomers, making the valve compatible with virtually all weather and service conditions. Its neoprene elastomer is offered with an algae and barnacle-resistant compound. Internal expanding clamps are available in 304 and 316 stainless steel, or carbon steel. 800/344-3246; www.procoproducts.com
