Danfoss BSV 8 Safety Relief Valves

BSV 8 is a standard, back-pressure independent safety relief valve, designed for protection of small refrigeration components against excessive pressure — and as a pilot valve for the pilot-operated internal safety valve, type POV. The angle-way design operates reliably even with very high back pressure, and the tightly sealed spring housing avoids refrigerant leakage.
