Proportional Valves at a glance
Kuhnke proportional valves are used for control and dosing of liquids like water or gases like oxygen.
The flexibility in adapting Kuhnke proportional valves regarding media compatibility or performance data creates possibilities for various applications. The flow of 2/2-way Kuhnke 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 Kuhnke proportional valves can be delivered as stand-alone product, moreover they can be designed as customer-specific valve manifolds or valve systems with control electronics.
Kuhnke standard proportional valves series 68P with 15 mm width reach flow rates of 0 to 90 Nl/min air.
The Kuhnke standard proportional valves series 63P with 10 mm width enlarge the field of possible applications in the area of low flows ranging from 0 to 30 Nl/min air.
