Description :
The disc valves (called also butterfly valves) are used to close and open the medium flow in the pipeline. When using the manual lever control, the disc valve has three basic positions: closed, open and half-open.
Closing of the butterfly valve with a regulating screw allows for greater accuracy of flow regulation. Control can be automated with electric or pneumatic actuators.
The butterfly valve consists of the valve body, two sanitary screw union connections (Standard of DIN 11851), neck, core, internal seal and control.
The internal seal of the valve is made of silicone or EPDM (according to version choosed).
This type of the disc butterfly valve is supplied in sizes DN25 up to DN100.
