7 Installation The Serie 0 check valve design allows a rapid and easy installation between standardized flanges : reduced weight and overall dimensions no additional pipe supports are required suitable for horizontal and vertical up flow no special tools are needed for installation low maintenance. The Serie 0 check valves, in the standard configuration, is offered with flat faces (FF). On request, raised faces (RF) can be supplied. The flange faces are machined Smooth finish (Ramax.:, )or Stockfinish. Optimum installation In a horizontal pipe, the check valve must always be installed with its hinge pin in the vertical position. CORRECT WRONG When the check valve is insered in a vertical pipe, it will function correctly only if the fluid moves upwards (for a fluid moving downwards, please consul us). In a piping system, some minimum distances must be rspected between the check valve position and a bend or a tee. The following drawings show some horizontal pipe configurations (viewed from above) in which the check valve is installed with its hinge pin in the vertical position. The minimum recommended distance for a check valve installed downstream from a bend, tee, pump or valve causing flow disturbance is diameters. When such a unit is downstream of the check valve, it is necessary to respect a distance of at least diameters. DN DN DN DN DN DN DN DN 7
