The range of safety relief valves Danfoss SFV, designed specifically to protect tanks against pressure overloads. The standard valves are dependent on back pressure. They are designed in accordance with safety requirements for refrigeration installations provided by 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. Standard pressure setting valves having "TÜV Pressure Setting Certificate".
The valves are designed for:
It is not recommended to use with flammable hydrocarbons
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. 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.
Danfoss valves are manufactured in accordance with the EU Pressure Equipment Directive (PED) and marked with the CE mark. For more information, please refer to the Installation Manual.
