Operating Principle of SV / SVS Valves
The SV / SVS series valves are butterfly shut-off devices designed to control the flow of liquids in processing pipelines. They operate in two positions:
-
Open – allows free flow of the product
-
Closed – completely blocks the flow
Switching between these positions is done by rotating the disc 90°:
-
In the manual version, the operator turns a handle.
-
In the pneumatic version, the disc opens using compressed air and closes via the force of an internal spring.
This makes the valve a simple and reliable solution for a wide range of hygienic and industrial processes.
