Safety Relief Valves & Change Over Valves for the Refrigeration Industry


Safety Relief Valves and Change Over Valves suitable for the following industries/applications:

  • Compressor manufacture
  • Industrial refrigeration
  • Commercial refrigeration
  • Ice making machinery
  • Air conditioning
  • R744 CO2 refrigeration
  • R717 Ammonia refrigeration (stainless steel valves)


    The Seetru range of safety valves for refrigeration applications are designed to meet the needs of the refrigeration industry, offering safety valve technology for compressor manufacturers, industrial refrigeration, commercial refrigeration, ice making systems and air conditioning. Safety valves are compact and designed with bonded sealing technology and the highest possible sealing performance to comply with the most stringent environmental standards.

    We have valves suitable for refrigerants HCFC, HFC, R717 (Ammonia), R744 (CO2)

    The models that use bonded elastomer sealing are leak tested to better than 10-5 mbar litres/sec on Helium. This is equivalent to a leakage rate of less than 1oz in ten years. Suitable for operating temperature in the range -30 °C to +200 °C.

    Manufactured in accordance with a wide range of international standards and approvals such as BS EN ISO 4126, TÜV (Germany) to AD Merkblatt A2, National Board UV Stamp to ASME Section VIII Division 1, EAC customs union (Russia, Belarus and Kazakhstan), CRN and compliant with the requirements of the Pressure Equipment Directive, PED (CE marked).

    Seetru safety relief valves are now supplied UKCA approved and marked
