American PARKER proportional valve structure principle

Brand PARKER/American Parker Features of PARKER proportional valves (USA): 1) Enables stepless adjustment of pressure and speed, avoiding the shock phenomenon during directional switching of normally open on/off pneumatic valves. 2) Enables remote and program control. 3) Simplifies the system and greatly reduces the number of components compared to intermittent control. 4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its re
