Instrument-Grade Proportional Valve Family Offers New Performance Range for Demanding Gas Control Applications


Parker Hannifin announces a ten-fold increase in the flow capacity of its highly successful miniature proportional valve product line. Gas flow ranges of 0.001 LPM to 240 LPM now can be controlled with common miniature form-factors, enabling a single valve to be used where two or three were previously required. The resulting space savings and reduced power consumption is critical for today’s light weight portable medical and analytical instruments.

The new capabilities build on the successful VSO® (voltage sensitive orifice) valve family which features “medical grade” leak specifications, analytically clean bodies, and proven reliability with over 100 million cycle life. The VSO proportional valves feature both barbed and face seal manifold bodies and three standard-control voltage ranges (0-5, 0-12 & -24 VDC).

The Pneutronics Division of Parker Hannifin provides precision control of inert and aggressive gas and liquid media through its full range of high performance miniature fluidic products and systems. With application-specific solutions ranging from miniature digital and proportional solenoid valves and pumps to electronic pressure control modules, Pneutronics meets the stringent operating requirements of OEM instrument builders worldwide.

With annual sales exceeding $9 billion, Parker Hannifin is the world's leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs more than 57,000 people in 46 countries around the world. Parker has increased its annual dividends paid to shareholders for 50 consecutive years, among the top five longest-running dividend-increase records in the S&P 500 index.
