Ansi forged swing check valves extract catalog api din - Fig. 39 | Comeval

The Ansi forged swing check valves from Comeval, as detailed in the extract catalog API DIN - Fig. 39, are designed to prevent reverse flow in piping systems using an articulated disc with a metal seat. These valves are known for their robust and simple design, making them easy to maintain and suitable for a wide range of applications. They offer diverse design combinations with various end connections such as flanged, BW, SW, and threads, and are constructed from different materials and trims. The nominal size range is DN10-DN50 (3/8"-2"), and they can handle design pressures from PN16 to 420 (ANSI Class 150-2500). Commonly referred to as non-return valves or backflow preventers, these valves are ideal for use in HVAC systems, steam, gases, and compressed air applications. They come with several certifications, including the Comeval PED Module H Certificate of Conformity and various EAC certifications and declarations.
