Shinwa Controls Co., Ltd. has successfully developed a three-way control valve capable of high-precision proportional flow control and will release it worldwide. Conventional three-way control valves required performance such as "quick mixing" and "rapidly achieving the appropriate temperature," but by improving the internal structure, we have realized this high-precision technology. In addition to precise temperature control, it now enables multi-stage precise temperature control, making it usable in a wide range of fields, from households to food, medical, and semiconductor industries.
