Safety Relief Valves

BSV 8

BSV is a standard, back pressure independent safety relief valve, especially designed for protection of small components against excessive pressure and as a pilot valve for the pilot operated internal safety valve, type POV.BSV is an angle-way safety relief valve which can operate with a very high back pressure. The valve is designed to meet the strict quality demands and safety requirements for refrigeration installations, specified by the international classification societies.As the valve is not dependent on the back pressure, it is recommended for use as an internal safety relief valve. However, the valve can also be used as an external safety relief valve. The spring housing is tightly sealed to avoid refrigerant leakage.The inlet flow diameter of the BSV 8 is 8.0 mm (5⁄16 in.).The valves can be delivered with set pressures between 10 and 25 bar (145 and 363 psig).Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve are also available.

SFA 10 / SFA 10H / SFA 15 / SFA 15-50

The SFA 10 and SFA 15 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 spring housing is closed tightly to avoid refrigerant leakage.The inlet flow diameters of the valves are:• 6.8 mm (¼ in.) for SFA 10• 13 mm (½ in.) for SFA 15/SFA 15-50The valves can be ordered with set pressure:• between 10 and 27 bar (145 and 392 psig) for SFA 10• between 28 and 65 bar (406 and 943 psig) for SFA 10H• between 10 and 40 bar (145 and 580 psig) for SFA 15/SFA 15-50Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve, are also available.

SFV

SFV 20 - 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:• 18 mm (3⁄4 in.) for SFV 20• 23 mm (1 in.) for SFV 25The valves can be delivered with set pressures between 10 and 25 bar (145 and 363 psig).Standard pressure setting valves having "TÜV Pressure Setting Certificate" with each valve, are also available.
