Technical parameters
Nominal pressure: 5.2MPa
Test pressure: 7.8MPa
Applicable temperature: -45℃ ~ +120℃
Applicable medium: Ammonia, Freon, CO₂, etc.
Characteristics
ASFV are standard, back pressure dependent safety relief valves in angleway 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 refigeration plants. The spring housing is closed tightly to avoid refrigerant leakage.The inlet flow diameters of the valves are shown in below table.
The valves can be delivered with set pressures between 12 to 40 bar g.(step 1 bar)
The safety relief valve should be fully open before the pressure is 10% higher than set pressure, and fully closed before the pressure is 10% below set pressure(See fig. below)
