HIGH RESOLUTION
ELECTRO-PNEUMATIC PRESSURE CONTROL
High resolution pressure regulators are ideal solutions for sensitive applications like low-pressure leak testing, micro-unit dispensing, and microfluidics. These devices can be used in any pneumatic process where accuracy and repeatability are important.

The MPV and QPV are ultra-high resolution, electro-pneumatic, closed-loop pressure control regulators. These units make use of true proportional valves instead of traditional on/off solenoid valves.
This feature and the field adjustable hysteresis potentiometers allow the MPV/QPV to achieve superior system resolution, accuracy and repeatability.
