Proco Products, Inc. would like to introduce the newest addition to the ProFlex™ line of Rubber Duckbill Check Valves – the newly engineered, low headloss Style 790 check valve, the only assurance to ZERO backflow. Where other products have failed in design and performance, Proco has spent countless hours in the engineering and design stages to ensure that the Style 790 will be your last and only requirement for a Low Headloss Inline Check Valve.
The Style 790 check valve is the elastomeric valve of choice for municipalities, airport runway runoffs, railway washouts, highway flood damage prevention and odor control. The 790’s unique design provides rapid dispersion of head pressures and with its low cracking pressure, it prevents upstream flooding.
The inline design of the Style 790 check valve allows the valve to be installed without having to do any modifications to existing structures or costly pre-install planning. The unique fold away design of the inner sleeve also allows for a near full port flow, allowing for quick drainage.
