Proportional Valves

KENDRION proportional valves are used for control and dosing of liquids like water or gases like oxygen. The flexibility in adapting KENDRION proportional valves regarding media compatibility or performance data creates possibilities for various applications. The flow of 2/2-way proportional valves can be controlled by current input variation. If used in closed-loop with appropriate electronics and sensors, the flow can be continuously regulated to specific levels.

Not only can KENDRION proportional valves be delivered as a stand-alone product, moreover they can be designed as customer-specific valve manifolds or valve systems with integrated control electronics.KENDRION standard proportional valves series 68P with 15 mm width reaches flow rates of 0 to 160 l/min air.The KENDRION standard proportional valves series 63P with 10 mm width enlarges the field of possible applications in the area of low flows ranging from 0 to 30 l/min air.

The Kendrion proportional valves of the series 63, 65 and 68 are used in dental treatment units, e.g. to supply drive air for drilling turbines or to control the spray water. The cost-effective design and the possibility to adapt the valve according to customer requirements ensure easy integration.

The proportional solenoid valves from Kendrion are used in ventilation and anaesthesia equipment. Due to the high cleanliness requirements and proportional characteristics the Kendrion proportional valves meet the high quality demands of medical technology.

The proportional valve of the 65 series is used to switch the water flow within washrooms. Due to its low power consumption, mechanical robustness and reliability, this valve type meets the high requirements of the aviation industry.

The electromagnetic proportional valves from Kendrion are used in mass flow controllers and measuring devices. Due to the optionally integrated control electronics for the integration of sensor signals, the valve is suitable for the reliable control of mass flow.
