Precision Redefined: KaoLu’s Smart Valves for Plastics & Rubber Machinery

KaoLu has a history of 45 year in Taiwan mainly manufacturing high-precision Proportional Pressure Regulator and modules that feature high pressure 50 bar, and high flow DN 45, which can be used industrial equipment such as linear/rotary PET bottle Stretch Blow Molding Machines that require high speed dynamic pressure change.

KaoLu is located in Taichung, Taiwan with manufacturing facility only in Taichung. KaoLu’s customers spans from industrial equipment ( PET bottle blow molding, laser cutting, tire making, automotive), medical device ( invasive, microfluidics), semiconductor ( wet and dry process, testing), aerospace( high pressure testing, mimetics)..etc. KaoLu’s distributors and sales partners are located in 13 countries. KaoLu is a ISO 13485 certified company.

Boosting Precision and Productivity in Plastics & Rubber Machinery with KaoLu’s Smart Proportional Valves

KaoLu specialize in delivering high-performance proportional control solutions that redefine precision, efficiency, and reliability in the plastics and rubber industry. KaoLu’s lineup of advanced Proportional Pressure Regulators, Proportional Flow Control Valves, and Proportional Pinch Valves is engineered to meet the dynamic needs of extrusion, injection molding, blow molding, and other key processes in the polymer field.

Unmatched Control with KaoLu’s Proportional Pressure Regulator

Designed for fast response and high accuracy, our electro-pneumatic pressure regulators ensure precise air pressure control in pneumatic-driven systems—essential for consistent product quality in molding and extrusion applications. With digital control and wide pressure range options, KaoLu’s Proportional Pressure Regulator help reduce cycle times, minimize waste, and boost overall machine performance.

Intelligent Flow Management with Proportional Flow Control Valve

KaoLu’s Proportional Flow Control Valves enable smooth and adjustable airflow regulation, making them ideal for temperature-sensitive and pressure-critical processes. Whether you're operating automated material handling or thermoforming equipment, our valves support fine-tuned flow modulation for better energy efficiency and process stability.

Clean and Contact-Free Operation with Proportional Pinch Valves

KaoLu’s Proportional Pinch Valves are a game-changer for applications requiring hygienic, contamination-free flow control, especially when handling viscous or abrasive media. With no direct contact between valve mechanism and media, they extend tubing life and reduce maintenance needs—perfect for precision dosing or feeding systems in rubber compound or additives.
