For years, DSM has worked with companies to develop proportional valve products using piezo actuators.  The interest has grown as product designers and managers learn how valves with proportional control capability can simplify and improve their systems. 

DSM does not design valves, but has learned how to work closely with valve designers to create efficient and cost effective solutions to drive valves.  Most applications require some actuator modification. However, as they are typically derivatives of our standard architectures, your project can be completed quickly with confidence in the outcome.  

Our customer's confidential data is treated with extreme care.  Much of what has been created over the years is proprietary and cannot be shown.  A few simplified examples can be seen above and below.  Most of DSM's actuator architectures are compatible with valve driving conditions and can be considered for your valve applications.

Contact DSM today to explore proportional piezo valves for your application.


Commercial Hydrocarbon Piezo Micro-Valve Actuator

Example of PRECISION piezoelectric actuator integrated into valve. 

DSM designed and fabricated a piezo actuator intended to control a microvalve.  The actuator was successfully incorporated in the path of flow.  Highlights included:

  • Proportional flow
  • 0 to 10 sccm
  • Up to 50 psi change in pressure
