TCB dry disconnect couplings

Product catalog summary
Product Overview:
TCB dry disconnect couplings are engineered for high-flow, anti-pollution fluid transfer applications, suitable for fluid processes, container loading/unloading, and temperature control systems. They ensure safe, reliable, and easy connections in challenging environments.

Key Advantages:
  • Enhances operator and installation safety.
  • Facilitates connection operations, even under pressure.
  • Boosts performance and efficiency.
  • Constructed from robust materials for resistance to high-pressure peaks and vibrations.
  • Features anti-pollution technology with a flat-face design to minimize air introduction and workplace pollution.
  • Includes a safe bayonet locking system for quick and reliable connections.
  • Ergonomically designed with a handwheel for ease of operation.

Available Options:
  • Extended design for use in limited spaces.
  • Colour coding for easy circuit identification.
  • Mechanical coding to prevent circuit inversion.
  • Stainless steel handwheel for use in aggressive environments.

Technical Specifications:
  • Available in sizes with hose nominal diameters from DN 25 to DN 100.
  • Maximum working pressure for stainless steel and Hastelloy® versions is 25 bar.
  • Operating temperature varies with O-ring type, with options for Nitrile, EPDM, FKM, and FFKM seals.
  • Connection options include female BSP or NPT threads, flanges, and tri-clamp connections.

How to Build Part Numbers:
Part numbers are constructed based on material series, type of seal, handwheel, colour code, mechanical coding, and regulatory options, with specific codes provided for each element.

Part Numbers:
Detailed part numbers are available for hose units and tank units, including specifications for dimensions, weight, and connection types. Accessories such as assembly tools and service kits are also listed.
