Automatic Control Valves

Hydro Instruments is a leader in vacuum chemical feed delivery systems. Their success can be attributed to the redesign of their chlorine auto-valve that eliminated gears and potentiometers in the drive mechanism and went to a linear stepper motor design. Additional product options incorporated into their chlorine flow pacing valve line included valve materials and software features, which allowed the expansion of the auto valves into the vacuum chemical liquid feed applications.

As the market changed and the need for additional features became apparent, new options were developed by our engineers. Listed below are our different valve options, including the new auto valve package that combines gas flow measurement and automatic flow control with comparative analysis software.
