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.
