Safety Devices and Tools

DCU-2

The DCU-2 type valves, with integrated the U-6 check valve is for Vapor/Liquid refrigerant applications.

Key Features

  • Tamper Proof: The unique check valve design prevents tampering such as using the cylinder for recovery.
  • Pressure retaining function: Maintains the integrity of the refrigerant gas in the cylinder and prevents gas contamination.
  • Backflow prevention: Keeps the inside of the cylinder clean and extends the life of the cylinder. Plus, prevents oil-containing contaminated gases from entering the cylinder.
