Need precise control for your air compressor? This pressure switch valve is built to handle the job. It works within a pressure range of 0.05 to 1.2 Megapascals (Mpa), has two G1/4 ports for connecting your lines, and includes a G1/8 port for a pressure gauge. The big deal here is the piston design – it gives you a flow rate about 30% higher than old-school diaphragm types and responds quickly and accurately. It uses reliable V-type sealing rings for great sealing that's wear-resistant, and the valve body even has an overflow port for fast pressure release when you need it. It's compact, lightweight (about 581g), and a breeze to install. Perfect for getting efficient, stable performance from your air system, whether you're in a workshop or on a job site.
