PIEZO

VALVES

Motorized valves are used throughout many of the largest industries such as medical devices, industrial and lab analysis equipment, food and drug, semiconductor, as well as aerospace and automotive. The vast majority of motorized valves rely on conventional EM motors, which can be bulky, slow responding and inefficient.

DTI has collaborated with a range of customers from different industries to develop customized motorized valve solutions based on DTI’s piezoelectric technology. The result has been a range of unique valves which have been shown to provide a superior slim-line and efficient design compared to conventional valves used in many applications. Furthermore, the DTI piezoelectric valves react faster and are more precise, while at the same time they consume zero energy in the hold position (for a list of advantages see table).

Conventional Motorized Valve Flow Control System

  • Two valves needed: (1) Fast-action “cut-off” (2) Precision-action “flow-control”
  • Long open/close times
  • Fluid flow control not precise
  • Reaction time slow
  • Consume power in hold position
  • Requires high energy; may spark
  • Overheating/burnout if jammed

Piezoelectric Motorized Valve Flow Control System

  • One valve performs as both “cut-off” & “flow-control” valve
  • 10-times faster open/close time
  • 50-times more precise flow control
  • 100-times faster reaction time
  • Consumes no power in hold position
  • Lower energy without sparking
  • Will not overheat or burnout if jammed
