Safety relief valves

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)
