Datasheet and documents

Description

ARI-CHECKO®-D Disc Check Valve:

  • Material: Stainless steel (1.4408).
  • Design: Clamping version, with a metallic sealing plug and optional soft sealing for low temperature applications.
  • Applications: Typically used for smaller diameter systems (DN15 to DN100).


Technical Data:

  • Kvs-Values: The flow capacity of these valves varies with size, ranging from 3.3 m³/h to 5207 m³/h for the larger valves.
  • Zeta-Values: The pressure loss factor ranges from 2.5 to 10.73 depending on the valve size and design.


Important Notes:

  • Operating Conditions: The valves are designed to function within a set pressure range, and the operating point should not fall into the unstable region.
  • Leakage Rate: The standard leakage rate for metallic sealing is Class C as per DIN EN 12266-1, while soft sealing can achieve Class A for better performance.
