Proportional Valves

Low hysteresis, compact and versatile

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.


Kendrion Proportional Valve

Even more efficient and versatile – the new proportional valve 68P!

Precise and reliable control of liquids and gases is essential for the high quality demands of medical and analytical technology. The 15 mm proportional valve by Kendrion is versatile and features optimal control characteristics, combining both - an unseen performance with an even higher commercial benefit.
Just in time for this year's world-leading trade fair Analytica 2022 in Munich, Kendrion has expanded the 68 series with the 15 mm proportional valve...



The Proportional Valve 68P offers precise control charcacteristics

Optimal control and dosing of gaseous media

The new 15mm Proportional Valve is efficient and versatile with a scalable nominal size from 1.3-2.5 mm.

It features optimal control and dosing of gaseous media such as inert gases or medical oxygen. Our animation shows the precise control characteristics and flow rates in the various opening positions. 

Discover how the new 68P proportional valve operates on the right.
