1. Structure: An air compressor pressure switch with a 1/4-inch outlet safety valve and 2 pressure gauges. It comes with a switch. The piston seal uses a V-shaped seal, which has good sealing performance, is wear-resistant, and stable. 2. Advantages: The piston structure has a flow rate 30% higher than that of traditional diaphragm types. 3. Function: The valve body structure has an overflow port for rapid pressure reduction. 4. Performance: The air compressor pressure valve switch features high precision and rapid response. 5. Features: The air compressor pressure valve switch is small in size, light in weight, and easy to install. The air compressor control valve regulator with a pressure gauge is used for rapid pressure reduction. 6. Main function: The main function of this valve is to adjust the shutdown pressure and startup pressure of the air compressor. 7. Features: It helps you save the electricity of the air compressor. It has high-precision voltage regulation and sensitive response. It comes with a switch lever and can be adjusted according to actual conditions. It is easy to install and use. 8.
