Product benefits Highly reliable function as check disc is accurately guided by three guide pins (up to DN 100). Integrally cast centering aid for easy installation. Low maintenance requirements due to corrosion-proof body made of brass (DN ) and spring made of stainless steel (all nominal diameters). Universal use: Valve can be installed between flanges to DIN EN PN 6-16, DIN EN PN 6-16, ANSI B /125, BS 4504 PN 16 and in any installation position. Short face-to-face length and low weight reduce transport and handling costs. Hydraulically favourable flow passage for minimum pressure drop.

5 Check Valves and Strainers Valve characteristics Volume flow rate (water) Vw (m 3 /h) DN Pressure loss p in mbar The values indicated in the diagram are valid for water at 20 C. They have been measured on valves installed in horizontal pipes. In vertical pipes insignificant deviations occur when the valves are partially open. To read the pressure drop for other fluids, the equivalent water volume flow rate must first be calculated using the following formula: Key Symbol Name V ẇ Equivalent water volume flow rate in m³/h ρ V Density of fluid handled (during valve duty) in kg/m³ Volume flow rate of fluid handled (during valve duty) in m³/h BOA-RVK 5
