I. Application:

The A28Y-16P stainless steel safety valve is suitable for equipment or pipelines with corrosive media at working temperatures ≤200°C, serving as an overpressure protection device. The A28HY type full-lift safety valve with handle, A28H full-lift safety valve are suitable for equipment or pipelines containing media such as air, steam, water, nitrogen-hydrogen mixture, etc., at working temperatures ≤200°C.

II. Principles for Selecting Safety Valves:

1. For steam boiler safety valves, generally choose open full-lift spring safety valves;

2. For safety valves used with liquid media, generally choose micro-lift spring safety valves;

3. For safety valves used with air or other gas media, generally choose closed full-lift spring safety valves;

4. For safety valves used in liquefied petroleum gas tank trucks or liquefied petroleum gas railway tank cars, generally choose full-lift internal safety valves;

5. For safety valves at oil well outlets, generally choose pilot-operated safety valves;

6. For high-pressure bypass safety valves in steam power generation equipment, generally choose pilot-operated safety valves with both safety and control functions;

7. If periodic opening tests are required for the safety valve, choose a safety valve with a lifting wrench. When the medium pressure reaches 75% or more of the opening pressure, the lifting wrench can be used to slightly lift the disc from the seat to check the flexibility of the safety valve opening;

8. If the medium temperature is high, to reduce the temperature of the spring chamber, generally when the operating temperature of a closed safety valve exceeds 300°C and that of an open safety valve exceeds 350°C, choose a safety valve with a radiator;

9. If the backpressure at the safety valve outlet is variable and its variation exceeds 10% of the opening pressure, choose a bellows safety valve;

10. If the medium is corrosive, choose a bellows safety valve to prevent critical components from failing due to corrosion by the medium.
