DN65 Ball Valve

Design and Features

A DN65 ball valve is a robust and high-pressure solution designed for use in CO2 refrigeration systems. With its substantial size and the capability to withstand pressures of up to 130 bar, this ball valve is a critical component in industrial refrigeration applications.

  • Seamless Bi-directional Flow
    The precision-engineered full port design allows for an uninterrupted bi-directional flow of carbon dioxide.
  • Adaptable Design
    DN65 size indicates compatibility with pipes and systems of a specific diameter, making it a versatile choice for various industrial settings.
  • Stainless Steel Body
    The NDL CO2 ball valves feature a stainless steel body for stainless steel a connections
  • Tested for High Quality
    Each valve is helium-tested at the factory to guarantee leak-free performance
  • Teflon Seals and Seats
    Reduce service calls, refrigerant loss, and environmental contamination with our cone-shaped 100% virgin Teflon seals and seats that will not shrink or leak, eliminating seal replacement during changeovers.
  • Bottom-Up Stem Installation
    Our stem placement is engineered from the bottom up. If there is an accidental over-pressurization in the valve, It will not blow the stem out and lose the charge. Plus, using the virgin Teflon seals ensures no need for seal replacement.
  • Unparalleled Warranty
    Our two-year warranty proves confidence. Every CO2 ball valve is tested and the serial number is stamped. Valves are cleanly packaged in poly bags and boxed to prevent contamination in transit to the job sites
