Clippard’s Eclipse proportional isolation valves are ideal for critical applications

Clippard’s Eclipse proportional isolation valves

One of the advantages of trusting industrial equipment from Wainbee Limited is the innovation. The supplier offers world-class solutions that always go a step further in fulfilling all of today’s and tomorrow’s manufacturing needs. For example, Clippard makes the Eclipse line of proportional isolation valves – two-way, stepper-controlled units that lead the industry in durability and performance. Each one achieves this stellar reputation by using the most powerful and robust miniature linear actuator available today.

Custom flow profiles enabled

The Clippard Eclipse valve series is the ideal pick for critical applications for liquid and gas delivery, and for medical, analytical, and industrial automation, when they require ultra-fine resolution and repeatability. Custom flow profiles are enabled by the unique design of these proportional isolation valves. Among other benefits are fast response (less than two milliseconds of reaction time), great linearity (less than four per cent of full-scale), no leaks (under 0.05 standard cubic centimetres per minute), life expectancy of more than 1,000,000 cycles, and repeatability of less than ½ a per cent of full travel.
