VSO - Proportional miniature valve
The Parker VSO® miniature proportional valve provides improved flow control for applications where precise flow control is required up to 56 slpm.
The VSO® valve provides precise flow control of gas in proportion to the input flow. The valve can be controlled by either DC or pulse width modulation along with closed loop control to provide optimum system performance.
Along with its ability to provide precise control over varying temperatures and media types, the VSO® miniature proportional valve is ideal for medical and analytical equipment manufacturers.

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 units. This improves both 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 performance. Assembly requires only a simple, machined manifold. -
VSO® LowPro - Proportional miniature valve for analysis
Parker VSO® LowPro GC is a powerful miniaturized proportional valve that regulates the flow rate of common carrier gases from less than 1 SCCM up to 6.5 SLPM. LowPro GC is less than half the size and weighs less than half the weight of competitive valves. It isolates the carrier gas from the valve spool with excellent leakage performance, very high resolution, and best-in-class flow control stability when operating under extreme environmental conditions. -
MD Pro - Proportional miniature valve
The Parker MD PRO is a miniature 2-way, normally closed (NC) proportional valve. It controls gas flow proportional to the input stream for flow rates up to 56 slpm. When used with closed loop feedback, the MD PRO is an economical solution that provides repeatable pressure and flow control. The Parker MD PRO is ideal for applications such as respiratory therapy, anesthesia delivery and patient monitoring equipment. -
