With the rapid advancement of automation and smart manufacturing, production equipment now demands increasingly higher precision and stability in fluid control. KaoLu Enterprise Co., Ltd., the first Taiwanese manufacturer to independently develop I/P and E/P proportional pressure regulators, has specialized in proportional valve technology for over 40 years. Guided by the philosophy of “Quality First, Innovation Always,” KaoLu is committed to delivering precise and stable flow control solutions widely applied in the plastics and rubber industry, medical equipment, and automated production lines.

KaoLu focuses on pressure proportional control solutions for the plastics and rubber sector, offering low-, medium-, and high-pressure proportional regulators to meet diverse application requirements. Our products feature high resolution and stable closed-loop control technology, enabling fast and accurate pressure output in processes such as compression molding, tire forming, and plastic/rubber blow molding.

Our latest ultra-high-flow proportional pressure regulator is specifically developed for PET rotary blow molding machines. Designed to maintain stable air pressure under high-speed, large-flow dynamic conditions, it meets the strict consistency requirements of bottle formation in the beverage packaging industry.

In addition, KaoLu provides a comprehensive range of water flow controllers for mold temperature controllers and chillers. By integrating proportional control technology with intelligent sensing, our systems precisely regulate cooling and heating water flow, improving operational efficiency and temperature stability.

Beyond our core proportional valve products, KaoLu has recently launched three new digital flow meters (for gas, water, and high-viscosity or corrosive fluids). Designed with lightweight construction, high accuracy, and modular integration in mind, these flow meters can be paired with proportional flow valves to provide monitoring and feedback control solutions for gas, water, and high-viscosity liquids.

Mr. Wu Jia-Mou, Founder of KaoLu Enterprise, stated:

“We understand that industrial customers do not simply need a valve or a sensor — they need a complete solution. From pressure proportional regulators to flow control systems and temperature control modules for mold temperature machines and cooling systems, our product lines are designed to help customers achieve the highest standards in efficiency, stability, and controllability.”

He emphasized that all KaoLu proportional regulators are independently designed and developed in-house, with continuous R&D investment to strengthen global competitiveness. With decades of expertise in proportional control technology, KaoLu products have been successfully implemented in semiconductor manufacturing, food processing, precision coating, medical equipment, and automated production lines.

Looking ahead, KaoLu will continue optimizing product structures to enhance control accuracy in high-flow and high-pressure environments while promoting the integration of intelligent sensing modules with IIoT systems, enabling more industries to achieve Industry 4.0 smart manufacturing goals.
