Exact process control
KIESELMANN control valves for liquids and gases regulate volume
flows and pressures in process plants. The selection of the appropriate valve
type depends on the application. The space-saving and cost-effective butterfly
valves with positioners are ideal for simple control tasks. For processes
requiring high control accuracy, KI-DS single-seat control valves are the right
choice
Butterfly valves with positioner: Space saving, cost-effective
Butterfly valves with positioner are the cost-effective solution
for simple control tasks in piping systems. The valve is actuated and regulated
by a digital electro-pneumatic positioner. The positioner, actuator and valve
form a closed control loop. A detailed description of the positioner can be
found here.
Single-seat
control valves: Highly precise and modular
The
versatile, hygienic single-seat control valves from KIESELMANN are available in
linear and equal-percentage versions. They are based on our proven KI-DS valve
concept and are suitable for sensitive production areas in the food and
beverage industry. The modular design with the large nominal diameter range
from DN 25 to DN 125 and the functionally graded flow coefficients offers
maximum flexibility - and the right valve for every application.
High
control accuracy and cavitation resistance
A major
advantage of our control valves is the replaceable cone and valve seat. If the
process conditions change, KIESELMANN control valves can be adapted quickly and
easily - without having to replace the complete valve. Within a nominal
diameter, the valves can be converted at any time to different flow
coefficients, control characteristics and seal types. With nominal pressures of
up to PN 16 as well as metallic and elastomeric sealing concepts, the valves
enable safe and precise process control and sealing.
Electropneumatic
positioner
Positioners
with M12 round plug and Bluetooth and USB interface are available for all
control valve types. The setting of the control range can be made in the
higher-level control.
It is
even more convenient via the Bluetooth interface. This makes it possible to
configure the valve directly on site with a tablet or smartphone. This is
possible even if the valve is installed difficult to reach. This ensures the
direct access to the process that many users have requested.
