Safety relief valves, type SFV 15 - 25

Introduction

SFV 15 - 25 are standard, back pressure dependent safety relief valves in angle-way execution, specially designed for protection of vessels and other components against excessive pressure. 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 inlet flow diameters of the valves are: - 13 mm (1/2 in.) for SFV 15, - 18 mm (3/4 in.) for SFV 20, and - 23 mm (1 in.) for SFV 25. Features Applicable for the refrigerants R 717 (ammonia, NH3), HFC, HCFC (e.g. R 22, R 134a, R 404a) and other refrigerants (dependent on sealing materials compatibility) within a temperature range of ­30°C/+100°C (­22°F/+212°F).

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.

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 R 717 (ammonia, NH3), HFC, HCFC (e.g. R 22, R 134a, R 404a) and other refrigerants dependent on sealing material compatibility 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)

Pressure Equipment Directive (PED) The SFV-valves are approved in accordance with the European standard specified in the Pressure Equipment Directive and are CE marked. For further details / restrictions - see Installation Instruction

Opening degree

SFV is designed as a standard safety relief valve (DIN 3320), which are recommended for refrigeration plants. On a rise in pressure above the set pressure, the safety relief valve will initially start opening slightly, to minimise the outlet of refrigerant. If the pressure continues to increase, the valve will open Connections Available with the following connections: Outside pipe thread T (ISO 228/1) Welding fittings (DIN 2448) Housing Made of special steel approved for low temperature operation. Spindle and seat are made of stainless steel, to ensure precise operation even during extraordinary conditions. The gasket of the valve cone is made of a special cloroprene (neoprene) compound. Installation To ensure exact operation of the safety relief valve it should be installed with the spring housing upwards. If the valve is mounted as an internal safety relief valve without any demand for exact opening pressure, the valve may be fitted with the spring housing in other positions. When the valve is mounted, it is important to avoid the influence of static, dynamic and thermal stress. A very precise technique has been applied for the production of the seal. However, this seal can still be damaged, if dirt is blown from the pipe system into the valve. It is recommended that safety relief valves exhaust into the open air with a U-pipe filled with oil on the discharge branch, to prevent dirt from penetrating into the valve. It is also recommended that the valves be installed in pairs in conjunction with the double stop valve type DSV 15 or 32. For further information please see the DSV data sheet.

fully. The safety relief valve will be fully open before the pressure is 10% higher than set pressure, and fully closed before the pressure is 10% below set pressure.

Re-calibration/servicing In certain countries the authorities demand that the valves are readjusted at least once a year (see local rules). Control/Identification After adjustment of the set pressure at Danfoss, the valves are sealed. For that reason Danfoss can only guarantee correct operation, as long as the seal remains unbroken. All valves are provided with a metal plate with the following information: - Flow diameter - Set pressure - Date of production - Production number - Type approved code. Transport/Handling The valves are fitted with special protection covers and packed into purpose made transportation cartons. It is important the cover remains fitted around the valve until it is installed. To ensure the exact and precise operation of the valve it must be handled with care.

Capacity

The design and construction of the safety relief valve has been tested and approved by TÜV. This test comprises control of the function of the valve as well as measuring of the capacity, which is the basis of the curves and tables on the following pages. The values in the table are based on saturated gas. Table 1.
