VSO Miniature Proportional Valve

*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

The Parker VSO® miniature proportional valve provides enhanced flow control for applications where precise control flow control is required up to 56 slpm. The VSO® valve provides precise flow control of gas in proportion to input current. The valve can be controlled with either DC current or pulse width modulation along with closed loop feedback to deliver optimal system performance. Together with its ability to provide precise control over varying temperatures and media types, the VSO® miniature proportional valve is ideally suited for manufacturers of medical and analytical equipment.
