KIESELMANN Einsitzventile KI-DS


Control valves for
exact process control


Control valves are used in process systems to specifically limit the volume flows and reduce the pressures in the production of liquid media.

KIESELMANN offers a large range of control valves for this. The choice of the suitable valve depends on the field of application. The space-saving and cost-efficient butterfly control valves are appropriate for simple control tasks. For processes which require a high degree of control accuracy, single-seat control valves on KI-DS basis are the right choice.

Butterfly control valves


Butterfly control valves

Butterfly valves are normally used as shut-off valves in pipeline systems. KIESELMANN offers a cost-effective control valve on the basis of the proven butterfly valves for simple control tasks. These butterfly control valves are available with screw connection or welded design as well as in intermediate flange design which is easy to maintain. In order to adapt the valve to the process, actuations with three different power levels are available. The control possibilities are the same as with single-seat control valves, but they don’t reach the same control accuracy due to the design-related moment of inertia of the sealing washer/flap.

The advantages for your plant:
Cost-effective control valve
Three actuations with compatible connections
     PDA 75 / PDA 100 /PDA 125
Intermediate flange design easy to maintain

Single-seat control valves

The multi-purpose applicable single-seat control valves made by KIESELMANN are available both in linear and equal-percentage version. The fittings are based upon the hygienic and proven concept of the KIESELMANN KI-DS valves. Their control accuracy and cavitation resistance were optimized in simulations and tests. Owing to a large range of nominal widths and Cv values as well as different connection variants, there is the suitable component for every application. The advantageous removable seat concept allows an easy adaptation to changing process conditions. Offering nominal widths of PN 10 as well as different metallic and elastomer sealing concepts, these valves allow the user a safe and exact process control and sealing.

The advantages for your plant:
Flexible removable seat concept
Metallic or elastomer sealing
Linear or equal-percentage control
Easy adaptation
