Dual plate check valve with centering lugs Series B6 25 Characteristics • DN 40 to 65 : 177 type. • DN 80 to 300 : 105 type. • PN 16 maximum working pressure. • Temperature: +1°C to +50°C. • Centering lugs valid for installation between flanges drillings such as ISO PN 6, PN 10, PN 16, ANSI 150, BS Table E/D, JIS 5K/ 10K. • Face-to-face dimension: • Internal coating elastomer. • Cassette type internal parts, allowing easy replacement (plates, shaft and springs). Mounting In case of a mounting on vertical pipe, the correct functioning of the valve will be ensured only if the fluid circulates from bottom to top (for fluid circulation from top to bottom, please consult us). Recommendation The minimum distances to be observed between the position of the check valve and any disturbing element (elbow, divergent, pump, valve, ...). Depending on the configuration of the circuit, certain minimum distances must be observed between the position of the valve and the one of a disturbing element such as elbow, divergent, pump, valve, etc. The mountings on the left represent horizontal pipe configurations (top view) with the check installed with axis of rotation in vertical position. The double check valve must be placed at 6 DN downstream of any disturbing element. For any disturbing element placed downstream of the valve, be sure to observe the particular instructions of the element and/or at l
