During operation, the medium flows in the direction indicated by the arrow.

This type of valve is designed to allow fluid flow in only one direction while preventing reverse flow.

Before installation, inspect the valve cavity and sealing surfaces to ensure there is no adhering dirt or grit.

Gate valves can be classified based on the configuration of their sealing surfaces into wedge-type gate valves and parallel-type gate valves.

Forged steel flanged gate valves—also known simply as forged steel gate valves—feature a valve body manufactured via a single-piece forging process.

Before installation, remove the protective covers from both flange ends and flush/clean the valve while it is in the fully open position.

These pneumatic flanged ball valves feature nominal diameters ranging from DN15 to DN300 and nominal pressure ratings such as PN16, PN25, PN40, PN6...

Low fluid resistance; the resistance coefficient is equivalent to that of a pipe section of the same length.

Pneumatic flanged ball valves require only a 90-degree pneumatic rotation and minimal torque to achieve a tight shut-off.

Select a stainless steel valve body or a fluorine-lined ball valve.
