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 inlet flow diameters of the
valves are: 18 mm (3/4 in.) for SFV 20, and 23 mm (1 in.) for SFV 25. The valves can be delivered with set
pressures between 10 and 25 bar g (145 and 363 psi g).
