Series FPV Flap Check Valves

Tag : Valves & Pumps

Series FPV Flap Check Valves prevent reversal of flow in pipingsystems. They are ideal where back flow could potentially causedamage to pumps, filters, or process equipment. The valves operatewithout the need for any adjustments or settings. Line pressuremoves the solid plastic flap off the elastomer seat, opening thevalve. When the inlet flow stops, back pressure moves the flap backonto the seat, stopping the flow. These flap check valves have beendesigned to provide excellent flow characteristics. Because oftheir straight-through flow design they have a lower pressure dropthan other check valve designs, and their compact size takes upless space in the pipeline than other types of check valves.Because of their all plastic construction, these valves will neverjam or stick as a result of rust or corrosion. Additionally, theywill not contaminate sensitive fluids that come into contact withthem. Series FPV Flap Check Valves are the valves of choice forcost sensitive applications that require a full featured, nocompromise valve.
These flap check valves are supplied with o-rings set into the bodyfaces. In most cases, flange gaskets are not required. Valves up to8" usually require a spacer and should always be used with the samematerial as the valve. Spacers allow full disc opening with minimuminterference. Spacers are not required for DIN and PVDF pipe.
