Check Valve

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.

Common applications of Check Valves include:

  • Food & Beverage
  • Dairy & Brewing
  • Pharmaceutical & Biotechnology
  • Cosmetics & Personal Care
  • Chemical

Features & Benefits

  • Hygienic Design: Crafted to meet the highest sanitary standards for clean-in-place (CIP) and sterilisation-in-place (SIP) processes
  • Forged Construction: Produced from high-grade, non-porous stainless steel forgings for corrosion resistance
  • Self-Draining: Eliminates product retention and ensures sanitary operation
  • Versatile Sealing Options: Multiple seal material choices available to suit a range of thermal and chemical environments
  • Long Seal Life: With adaptable sealing material choices

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 forces

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
