HF Pro - Proportional miniature valve
The Parker HF PRO is a miniature 2-way, normally closed (NC) high flow proportional valve. It controls gas flow proportional to the input stream and can deliver flow rates up to 60 slpm at 50 psig.
The valve can be controlled with either DC or pulse width modulation. It can also be used in conjunction with closed loop to provide optimum system performance. The Parker HF Pro miniature proportional valve is an ideal choice for applications requiring repeatable pressure and flow control, such as respiratory and patient monitoring applications.

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. -
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.
