Check Valve

These Sanitary Check Valves, often referred to as Non-Return Valves, are used to ensure fluid flows in a single direction within process piping systems, preventing any undesired reverse flow. Designed to meet stringent hygienic and sanitary requirements, Cipriani Harrison’s 64-Series and 65-Series Check Valves deliver exceptional reliability, cleanability, and performance across a range of applications.

Product Range

64-Series Check Valve

  • Design: Two-part forged valve body assembled with a sanitary clamp and sealed with a standard gasket
  • Operation: Spring-assisted closure; opens when upstream pressure exceeds downstream pressure plus spring force
  • Special Features:
    • Heavy-duty disc construction resists pressure hammer
    • Guided valve plug design for consistent, repeatable operation
    • Minimal flow resistance to maintain process efficiency

65-Series Check Valve

  • Design: Forged or bar stock construction with dead-weight closure (no spring)
  • Operation: Ideal for low-pressure applications requiring non-return functionality
  • Special Features:
    • Specifically designed for horizontal installations
    • Excellent for delicate product flows and low-pressure lines
    • Fully self-draining to avoid residual accumulation
