Butterfly valves, type 440xx-448xx

The use of butterfly valves has proven effective for many years in hygienically non-critical processes in the food industry. They represent a cost-effective possibility for the control and regulation of process media.

The wide range of versions available offer an optimal valve solution for almost every application. The butterfly valve can also be used in the conveying of liquids in other industrial areas.

Control butterfly valve

Simpler and more cost-effective solutions can also often be used in liquid and gas control such as the Handtmann control butterfly valve.

A modified Handtmann rotary drive is equipped with a specially developed and adjusted control unit.

The foreseen control range of the butterfly valve is "intelligently linearized" by means of the control unit. There software contains correction factors, which can adjust the theoretical opening value of the butterfly valve to the linear value depending on the nominal size. This allows considerably improved control characteristics. The tolerance range is 1-2% in the control in the CIP circuit and pressure tank cellar.
