The valve is designed to meet the strict quality demands and safety requirements for refrigeration installations, specified by the international classification societies.

The valve is recommended as an external and internal safety relief valve in refrigeration plants. The spring housing is closed tightly to avoid refrigerant leakage.

The valves can be delivered with set pressures between 10 and 25 bar g (145 and 363 psi g).

Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve, are also available.

Applicable for the refrigerants HCFC, HFC, R717 (Ammonia), R744 (CO2) within a temperature range of -30°C/+100°C (-22°F/+212°F).

Classification: To get an updated list of certification on the products please contact your local Danfoss Sales Company.

Technical data

Refrigerants Applicable for the refrigerants HCFC, HFC, R717 (Ammonia), R744 (CO2) within a temperature range of-30°C/+100°C (-22°F/+212°F). Flammable hydrocarbons are not recommended. For further information please contact your local Danfoss Sales Company.

Pressure Pressure setting range: 10 - 25 bar g (145 - 363 psi g). For further information please contact your local Danfoss Sales Company. The valves are designed for: Strength test: 43 bar g (624 psi g) Leakage safety: Same as set pressure Important: The SFV safety relief valve is dependent on the back pressure (if the back pressure is higher than the atmospheric pressure, the opening pressure will be higher than stated set pressure). Special circumstances such as vibrations (which should be avoided) and oscillating pressure may require an increased difference between the operational pressure and the closing pressure.

Pressure setting The operating pressure of the plant should be at least 15% below the set pressure. This allows a perfect re-seating of the safety relief valve after having been activated.

Temperature range -30/+100°C (-22/+212°F)
