<p>Disclosed is: (i) a molding system (100) having a hydraulic valve (200; 300; 400), (ii) a molding system (100) having: (a) an extruder (102), (b) a hydraulic circuit (116), and (c) a hydraulic valve (200; 300; 400), (iii) a hydraulic valve (200) of a molding system (100), (iv) a method (160) of a molding system (100) having a hydraulic valve (200; 300; 400), and (v) a valve controller (118) performing a method (160) of a molding system (100) having a hydraulic valve (200; 300; 400). The hydraulic valve (200; 300; 400) includes: (i) a valve sleeve (202; 302; 402) that is configured to convey a pressurized hydraulic fluid (117), and (ii) a valve spool (210; 310; 410) that is movable relative to the valve sleeve (202; 302; 402), once the valve spool (210; 310; 410) is made to move from a valve-closed position to a valve-opened position, the valve spool (210; 310; 410) is imparted with a running start before the pressurized hydraulic fluid (117) is permitted to flow out of the valve sleeve (202; 302; 402).</p> |
