BVB-SUFM20 : Ball valve DN20 (full-flow) with connections : Sanitary screw union / female | Sanitary screw union / male (DIN 11851), stainless steel / B-design

Ball valve DN20 with inlet DN20 DIN 11851 “Sanitary screw union / female thread” and outlet DN20 DIN 11851 “Sanitary screw union / male thread”. For use with pipe lines or tanks equipped with the DN20 DIN 11851 Sanitary screw union connections.

The ball valves are used to close and open the medium flow in the pipeline. When using the manual lever control, the ball valve has three basic positions: closed, open and half-open.

Closing of the ball valve with a regulating screw allows for greater accuracy of flow regulation. Control can be automated with electric or pneumatic actuators.

The ball valve consists of the valve body, two sanitary screw union connections (Standard of DIN 11851), neck, ball, seal and control lever.

The internal seal of the valve is made of PTFE (teflon).
This type of the ball butterfly valve is supplied in sizes DN10 up to DN150.

Important information regarding the chemical cleaning these ball valves (B-design) :

These ball valves feature an easy-to-clean design, free of external areas that are difficult to access, and allow for simple disassembly to clean internal components. For thorough disinfection of the internal parts, the ball valve must be disassembled, and each component treated individually in a bath containing a cleaning and sterilizing agent.
But it is not possible to fully clean the internal parts of the ball valve or achieve its complete bacteriological sterility without disassembling it.
