This Check Valve consists of a contoured cone optimizing the pressure loss during the passage of the fluid

The spring makes it possible to control the closing of the valve regardless of its installation position. This valve can be used in a horizontal position.

A pressure of 0.1 bar is necessary to overcome the force of a standard spring or 0.5 bar for a “strong” spring in normal use in the flowing direction.

A counter pressure of 0.3 bar is necessary to keep tightness in the non-flow direction.
