Compact
and cost-effective 

KIESELMANN
leakage butterfly valves are the cost-effective and space-saving solution for
safe product separation in process plants. They are used as reliable shut-off
devices on panels and containers. In contamination-sensitive areas, you can
offer extra security. A leak caused by seal wear can be detected and corrected
immediately.

KIESELMANN
leakage butterfly valves are generally available in intermediate flange
version. This construction and the split housing allow the seals to be easily
and quickly replaced.

Modular for individual solutions

Of
course, you do not have to do without automation in this cost-effective
leak-proof valve sector. Our modular system makes it possible to change over
quickly and easily from manual to pneumatic drive without removing the valves
from the piping system. The drives are available with sensors or control head
KI-TOP. KIESELMANN pneumatic rotary actuators are characterised by a
particularly high torque. The closed version in stainless steel housing is
completely maintenance-free. We give you a 5-year guarantee. The standard
position indicator lets you know at any time how the valve is switched. The
practical end position detector ensures permanently reliable feedback without
the hassle of readjusting the limit switches. Our pneumatically driven leakage
butterfly valves can be equipped with sensors or KI-Top control heads.
