New! The Eclipse: Proportional Isolation Valve

A proportional isolation valve like no other...

Utilizing the industry's most robust and powerful miniature linear actuator, the patent pending stepper-controlled Eclipse proportional isolation valve leads the industry in performance and durability. This valve is ideal in critical applications for liquid and gas delivery, medical, analytical and industrial automation requiring ultra fine resolution and excellent repeatability. In addition, the unique design allows for custom flow profiles.

Eclipse Proportional Isolation Valve

Primary Eclipse Benefits:

  • Leak free (<0.05 sccm)
  • Excellent linearity (<4% of full-scale)
  • Fast response (<2 ms reaction time)
  • Cycle life of typically >1 million
  • Repeatability <0.5% of full travel
