Proportional Pressure Regulators
Proportional Pressure Regulators
- Complete closed-loop servo system. Comprising of two solenoid valves, an internal pressure transducer, and electronic controls. Based on analogue signals, the pressure is controlled by two solenoid valves to maintain precise pressure; one valve functions as inlet control, the other as exhaust. The pressure output is measured by an internal or an external feedback pressure transducer that provides a feedback signal to the electronic controls

Proportional Flow Control Valves
Proportional Flow Control Valves
- Proportional solenoid valve:The proportional flow control solenoid valve converts the input current signal into a mechanical signal output, and then controls the flow. This type of proportional valve has fast response time, compact in size, and is suitable for installation on manifolds. Available flow ranges are 0-32L/min, 0-140L/min, 0-300L/min.
- Stepper-controlled proportional valve for air and liquid:Kao Lu stepper-motor driven proportional valves control flow ranging from 0 to 20 LPM, 120 LPM, 300 LPM and up to 1000 LPM. Our stepper-motor driven proportional valves are ideal for controlling a variety of media such as water, gas, oil, etc. Kao Lu stepper-motor driven flow proportional valves also have the advantages of low hysteresis (<2%) and high resolution (20ml/min)
Proportional Pinch Valves
Proportional Pinch Valves
- KAO LU Pinch Valve range:KAO LU is one of the biggest pinch valve manufacturers and supplies three types of high-quality pinch valves that can be used for high-precision sterile flow control: proportional pinch valves, pneumatic cylinder pinch valves, and miniature solenoid pinch valves. KAO LU solenoid pinch valves have the advantages of strong clamping force, low power consumption, high stability, durability, precise flow control, and fast loading and unloading.

Medical Biotechnology Valves
- The KAO LU range includes solenoid valves for running fluid, fittings, proportional flow control valves, various sensors... and other products. Various solenoid valves have the characteristics of fast response time, low power consumption, miniature design and long life time. There are various solenoid valves for oxygen, analytical equipment and are corrosion resistant.
The solenoid valve for fluid uses a separate membrane to minimize the uncontrollable interval and is not easy to be contaminated. Fittings series are made of PPSU high temperature resistant material, PVDF corrosion resistant material, stainless steel material... etc., all comply with FDA regulations and are very suitable for food, chemical industry, medical equipment industry and other applications. In addition, there are various sensors used in medical equipment, such as non-invasive flow sensors, single-point liquid level sensors, air bubble sensors, metal pipe air sensor, etc
