Proportional Valve

Clippard released its Eclipse stepper-controlled proportional valve that features a patent pending ceramic sliding seal and allows for custom flow profiles. Designed for industrial automation applications requiring ultra-fine resolution and repeatability, the valve is liquid and air capable with flow resolution to 0.19 ml/min water and 0.007 l/min air max at 30 psig. It has zero dead volume and is leak free (< 0.05 sccm) with linearity at <4% of full-scale and repeatability at <0.5% of full travel. www.clippard.com
