Specifications

  • Sizes: 3/8" to 2.1/2"
  • Connections: Flanged or Screwed
  • Materials: Steel or Stainless Steel
  • Medium: Glycol-based cold brine refrigerant EN 378 p. 1, including NH3, R134a, R290 (propane), R507, and blends with refrigerator oil, as well as neutral gas and liquid media
  • Set Pressure: 4 to 63 Barg (dependent on size)
  • Temperature Range: -60 to +180 °C Max

Design Notes: Custom designs to alleviate back pressure can also be provided.

Investing in our refrigeration safety valves will enhance the safety and reliability of your industrial refrigeration systems, ultimately ensuring operational efficiency and compliance with relevant safety standards.
