Diamond Series 3 Pressure Relief Valves

Designed to meet the changing needs of the process industry, the new Series 3 Pressure Relief valve uses elements of the DPL single and double seat valves to produce a full bore, self draining device ranging in size from 1-4”.
Available in manual and actuated format, the Series 3 valves have a tamper-proof pressure setting mechanism which can be adjusted in-line.
The valve can be disassembled for servicing without affecting the factory pressure setting.

  • Full bore.
  • Self draining to reduce the risk on contamination
  • Profiled seat seal to ensure a secure seal
  • 316L forged material for better corrosion resistance
  • Captive spring to ensure consistent system pressure settings
  • Wide range of seat materials appropriate for a wide range of applications
  • Suitable for CIP for full compatibility with your process systems
  • Steam sterilisable giving you complete peace of mind
  • Serviceable in-line to avoid costly downtime during maintenance
