Featured Products

Electronic Pressure Regulator

By incorporating patented technology, Kelly Pneumatics electronic pressure regulators provide exceptional closed-loop, proportional control over output pressure. Fast response, coupled with high resolution, repeatability and excellent linearity ensure the stability needed by processes that are sensitive to pressure variations.

Mass Flow Controller

Kelly Pneumatics, Inc. offers a reduced cost, single-valve design Mass Flow Controllers with PID control circuitry. Using either an externally supplied dynamic/static input signal or an onboard adjustable set-point value, these products provide exceptional closed-loop, proportional, output flow control characteristics. By utilizing patented proportional valve technology, our Mass Flow Controllers perform with excellent resolution and repeatability.

Digital Mass Flow Meter

The Digital Mass Flow Meter accurately measures and displays mass flow rate, volumetric flow rate, gas temperature, atmospheric pressure and gas pressure, for both Air and Oxygen. Unlike most flowmeters, the Digital Mass Flow Meter has a touch screen interface, offering immediate customization in seconds.

Regulated Proportional Valve

This valve dynamically compensates for varying inlet pressures, while still maintaining consistent output flow characteristics. Effective in applications with either fluctuating or oscillating control pressures, the Pressure Compensating Proportional Valve can maintain flow rates with input pressures reaching 250 PSIG.
