Safe and cost-effective 

Guth leakage double-butterfly valves are the cost-effective solution for safe product separation in process plants. With two flaps separated by a leakage space, they  offer extra safety in areas where contamination is critical. Switching is done using a handle, which switches both flaps simultaneously via a mechanism. They are used as reliable shut-off elements on panels, containers and pipelines. A leak caused by seal wear can be detected and corrected immediately.

Guth leakage double-butterfly valves are also available in the maintenance-friendly intermediate flange design. This design allows the seals to be exchanged with little effort and quickly.

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. Guth 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.
