Proportional valve ECLIPSE EIV-series

electrically-actuatedisolationfor water

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. Primary Eclipse Benefits: •Leak free (<0.05 sccm) •Excellent linearity (<4% of full-scale) •Fast response (1 million •Repeatability <0.5% of full travel Medium Liquids and gases Typical Cycle Time for Full Travel 1.1 seconds at 1,000 steps per second Wetted Material Ceramic (others depending on porting option) Pressure Range Vac to 30 psig (highly modifiable) Proof Pressure (Overpressure) 50 psig Flow Range Air: 0 to 8.0 l/min -0/+10% (0.28 scfm) @ 30 psig Water: 0 to 210 ml/min -0/+10%(0.0074 scfm) @ 30 psig Flow Resolution 0.19 ml/min water and 0.007 l/min air max @ 30 psig per full step depending on pressure Position Resolution 0.00006" Ambient/Environment 32 to 180˚F Driver Bipolar chopper drive required Supply Voltage to Motor Driver 20 VDC @ 30 psig Current/Phase 0.49 amps Mounting Manifold or flat bottom (ZDVF) Power Consumption 2.5 watts nominal only during adjustment, zero power consumption to maintain position Seals Valve: None Port: FKM standard, EPDM and others upon request
