[Hardware Net] The A28X-16T safety valve is used on the air compressor to provide safety protection in the air compressor working system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas/fluid in the system is discharged into the atmosphere/pipe, so that the system pressure does not exceed the allowable value, thereby ensuring that the air compressor does not cause an accident due to excessive pressure.
The price specifications of A28X-16T safety valve are as follows:

The main parameter of the air compressor safety valve is the displacement. This displacement is determined by the diameter of the valve seat and the opening height of the valve disc. It is divided into two types: the micro-open type and the full-open type. The micro-open type means that the opening height of the valve flap is 1/40 to l/20 of the throat diameter of the valve seat. Full-open means that the opening height of the valve flap is 1/4 of the throat diameter of the valve seat.
Air compressor safety valve selection
The operating pressure determines the nominal pressure of the safety valve, and the operating temperature determines the operating temperature range of the safety valve. The calculated constant pressure value of the safety valve determines the constant pressure range of the spring or the lever, and then determines the material of the safety valve according to the medium used. According to the structure type, the throat diameter of the safety valve is calculated according to the relief valve discharge amount. The following are general rules for the selection of safety valves. (l) Hot water boilers generally use a non-closed wrench with a micro-opening safety valve. (2) Steam boilers or steam pipes are generally closed with a full-opening safety valve with a wrench. (3) Liquid incompressible medium such as water generally uses a closed micro-opening safety valve or a safety relief valve. (4) High-pressure feed water generally uses closed full-open safety valves, such as high-pressure feed water heaters, heat exchangers, etc. (5) Compressible media such as gas generally use closed full-open safety valves, such as gas storage tanks, gas pipes, and the like. (6) Class E steam boilers generally use static weight safety valves. (7) Large-diameter, large-displacement and high-pressure systems generally use pulse-type safety valves, such as temperature-reducing and decompressing devices, power station boilers, etc., as shown in Figure 8. (8) Built-in safety valves for train tank cars, car tankers, storage tanks, etc. for transporting liquefied gas, as shown in Figure 4. (9) The top of the tank is generally equipped with a hydraulic safety valve, which is used in conjunction with a breathing valve. (10) Pilot-type safety valves are generally used for downhole drainage or natural gas pipelines, as shown in Figure 6. (11) A safety return valve is generally used on the liquid phase return pipe at the outlet of the tank pump of the LPG station. (12) Vacuum negative pressure relief valves are generally used in systems where negative pressure or negative pressure may occur during operation. (13) Bellows safety valves are generally used for containers or piping systems where the back pressure fluctuates greatly and is toxic and flammable.
