Ball Check Valves
Ball Check Valve TIN Covered
For tight sealing, low wear, fast cycle times
Application Fields:
Processing of low-viscosity or abrasive melts.
Function:
The melt passes through the radial inlet channels, around the ball and into the injection nozzle. The force of the melt flow keeps the ball pushed forward. In the injection cycle, the moulding pressure presses the ball back against the sealing ring, therefore preventing backflow.
Available Dimensions:
Ball check valves are available for screw diameters = 45 mm and are used in place of conventional check valves.
Low Wear:
Unlike conventional check valves, ball check valves are subject to almost no wear. This is highly beneficial from a technical standpoint and provides substantial cost savings. In most cases, only the sealing ring and the ball need be replaced at infrequent intervals. Profiting from advantages like this, many users of ball check valves see no need to return to using conventional check valves.
