- Key Products/Technologies
- Electronic Pressure Regulators: A wide range of pressure control capabilities from 0-2 inches of water column to over 5,000 psi. Key models include QB1X, QB2X, QB3 (up to 25 SCFM), QB4 (up to 200 SCFM), QBS (high pressure, low flow from vacuum to 500 PSI), QPV, MPV (ultra-high resolution ±0.005% F.S.), and MM Series. These are core products for precise pneumatic pressure control.Electronic Pressure Regulators: A wide range of pressure control capabilities from 0-2 inches of water column to over 5,000 psi.

These are core products for precise pneumatic pressure control.
- Air Flow Control Valves: Solutions for precise closed-loop control of compressed air, gases, and liquids. The FCV (Flow Control Valve) is an electro-pneumatic proportional angle seat valve, featuring closed-loop control via LVDT feedback and a high resolution of ±0.3%. It offers a maximum Cv of 19 and handles pressures up to 250 psi.Air Flow Control Valves: Solutions for precise closed-loop control of compressed air, gases, and liquids.

- Mass Flow Control Valves and Transducers: Closed-loop electronic mass flow controllers managing flow rates from 2 SCFH to 250 SCFM. The F-Series is a real-time mass flow transducer for air and inert gases, providing fast response (<10ms) and robust resistance to shock and vibration. DSB, DST, and DSW Series industrial pressure transducers accurately measure gas and fluid pressures, converting them into electrical signals.Mass Flow Control Valves and Transducers: Closed-loop electronic mass flow controllers managing flow rates from 2 SCFH to 250 SCFM.

DSB, DST, and DSW Series industrial pressure transducers accurately measure gas and fluid pressures, converting them into electrical signals.
- Advanced Control Technology: Unique control technology for superior accuracy, resolution, and repeatability. Implementation of 'dual loop' closed-loop control, combining internal transducers with external downstream sensors for precise control in diverse processes and applications. Ultra-high resolution pressure control achieved through a true proportional solenoid valve coupled with an analog PID control circuit. Robust product design, immune to shock and vibration (up to 20-25 Gs).Advanced Control Technology: Unique control technology for superior accuracy, resolution, and repeatability.
