A valve () comprising a bore () extending about an actuation axis (A), wherein a spool () inside the bore () is actuated between a first working position and a second working position, and a first circumferential seal wing (A) and a second circumferential seal wing (B) being arranged on the spool (). In the first working position, the first seal wing (A) abuts to an outer first recess wall () and the second seal wing (B) abuts to an inner second recess wall (), so as to open some flow paths and close other flow paths. In the second working position, the first seal wing (A) abuts to an inner first recess wall () and the second seal wing (B) abuts to an outer second recess wall (), so as to close some flow paths and open other flow paths.

Directional control valve and a sealing arrangement therefore

A stretch blow molding system () is provided. The stretch blow molding system comprises a cylinder () including a movable stretch rod () and a blow-mold valve (). The blow-mold valve () comprises a first fluid port () in fluid communication with a first pressurized fluid source (). The blow-mold valve () also includes a second fluid port () in fluid communication with a second pressurized fluid source (). A third fluid port () of the blow-mold valve is in fluid communication with the cylinder () and selectively in fluid communication with the first fluid port () and the second fluid port ().
