A system and method of regulating a pressure of a fluid with a valve block having a valve block inlet in fluid communication with an outlet of an extruder and a valve block outlet in fluid communication with a die. A transducer in fluid communication with the flow channel and in signal communication with a controller of the motor can sense a pressure and communicate the pressure to a controller of a motor. The motor can adjust a position of a valve to regulate the pressure of the fluid.

A method for closing a facility (1) for extrusion of a profiled element (2) comprising a roller (3) supported by a bearing (4), a tool module (10) intended to interact with the roller (3) so as to form an air gap (12) for shaping the profiled element (2), and at least a first head module (13) having a first extruder (14) comprises an engagement step (s1), during which the tool module (10) is urged against the first bearing (4) by a preload force (F_Z), in an engagement direction (Z), then a clamping step (s2) during which the tool module (10) is clamped between the first head module (13) and a second head module (23), on either side of the tool module (10), and by subjecting them to a clamping force (F_X), in a coupling direction (X) which is transverse to the engagement direction (Z).
