Fluid control valve with minimized turbulence: Eclipse
A revolutionary control valve that applies stepping motors to flow control.
Eclipse is an electromagnetic proportional control valve that enables high-precision and fine fluid control. By integrating high-performance micro-stepping motor drive with a unique slide-plate valve mechanism developed through exceptional processing technology, it has successfully achieved a durable structure and high-precision continuous fluid control technology. The valve (liquid contact part) employs a ceramic plate that combines high durability and corrosion resistance, making it adaptable to a wide range of fluids from gases such as air and gas to various liquids. It also enables "zero dead volume," which is an important factor when handling high-purity fluids, providing users with more comfortable and reliable results. ● Fine resolution (flow rate: 0.2 ml/min*, position: 1.5 μm/step) *at 207Kpa, fluid: water ● Excellent response (< 2 ms) and follow-up (error > 4%), as well as reproducibility (< 0.5%) ● The valve unit, which is the liquid contact part, is made of ceramic with high durability and corrosion resistance ● Zero dead volume specification ● Adaptable to a wide range of fluids including air, gas, and liquids <Showroom> You can see a demo of Eclipse at the TFT Building, just a 3-minute walk from Tokyo Big Sight.
