V-ring piston: The double pipe outlet alloy air compressor has a V-ring piston seal, which has very good sealing ability, strong wear resistance, stable performance and long service life.<br> Feature: This switch pressure regulator valve fitting has the features of high precision, stable performance, stable voltage, fast response speed, convenient and durable, easy to install and disassemble<br> Design Piston design: The air compressor control valve adopts a piston-type structure, and the flow rate is 30% higher than that of the conventional diaphragm, which is economical and efficient, and can help save electricity when used.<br> Good performance: The copper on both sides of the air regulator is the exhaust valve, which can be opened when using gas. This product can be installed with the original gas meter structure, and the original gas relief valve is widely used.<br> Convenient: The valve body structure overflows and decompression is quick and intuitive. The main function is to set the stop and start pressure of the air compressor. Users can adapt according to their actual situation.<br> The valve body structure overflows, and the pressure relief is quick and intuitive.
