VSO® LowPro - Proportional miniature valve

The VSO® LowPro is a miniature proportional valve that regulates the flow rate of inert gases at pressures up to 100 PSIG (6.9 bar). Typical flow rates up to 57 SLPM with a typical power requirement of 1 watt at room temperature.

With a width of only 16 mm and a height of 14 mm, the valve can be mounted in the smallest portable devices. This improves performance, size and weight.

The valve has orifice sizes from 0.030 inch (0.76 mm) up to 0.080 inch (2.03 mm). It weighs only 12 g.

Despite this, VSO® LowPro can perform the same function as valves three times its size, without compromising on performance. The assembly requires only a simple, machined manifold.
