Compatibility
Danfoss SVL Flexline CHV-X SS check valve. Select by nominal size (25 mm / 1 in), flow body (angleway) and connection standard (ASME B 36.19M Schedule 40 butt weld). EN 10220 and ASME weld-end preparations are not interchangeable — confirm the mating pipe schedule before ordering. Check-only; where an integral hand shut-off is also required, use the SCA-X stop/check valve of the same size. Mount with the embossed arrow in the direction of intended flow.
