The proportional control valve "Eclipse," which enables precise flow control, was featured in the Nikkan Kogyo Shimbun.

サンワ・エンタープライズ サンワ・エンタープライズ
The daily industrial newspaper with a circulation of 420,000 copies (May 27, 2021 issue) featured the proportional flow control valve "Eclipse." Eclipse is a completely new proportional control valve that achieves precise flow control by applying a stepping motor. The slide plate (liquid contact part) uses a ceramic material that excels in durability and corrosion resistance, making it suitable for a wide range of fluids from gases such as air and gas to various liquids. It is ideal for applications that require precise and reliable fluid control, such as medical devices, analytical instruments, and pharmaceutical manufacturing processes.

Proportional control valve Eclipse that achieves precise flow control.

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 structure with excellent durability and high-precision continuous fluid control technology. The valve (liquid contact part) employs ceramic plates that possess 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 responsiveness (< 2 ms) and follow-up capability (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
