VSO Max Miniature High Flow Proportional Valve

VSO Max Miniature High Flow Proportional ValveThe VSO®- MAX is a high flow miniature proportional valve that provides maximum flow capabilities to 240 s/lpm while consuming less than two watts of power. The valve delivers a high rate of controllable flow while consuming 25% less power than comparable miniature proportional valves. The VSO®- MAX miniature high flow proportional valve is an ideal solution for applications requiring low hysteresis and fast response, such as ventilators with fresh breathing circuit gas delivery, as well as other medical, analytical, and pathogen detection devices. This valve can be used with inlet pressures of 5 to 60 psi/g and features three standard control voltage ranges (5, 12 and 24 VDC).
