- - The shutter groups are integrated directly on the distributor or housed in the bottom plate.
- - Multiple shutter needle actuation systems for close-range applications with shutter needle adjustment and exclusion options.
- - All shut-off assemblies include a piston housing, simplifying machining and assembly.
- Durable sealing with high heat resistance to reduce premature failure.
- - Solutions with sealing groups for both hydraulic and pneumatic operation.
- - Needle and guide bushing needle plug, perfectly coupled and easy to replace.
- - Higher resistance to material loss due to the needle guide bushing.
- - Needle of the plugging group with conical or cylindrical finish.
- - Needle adjustment is possible for most shutter group cylinders without removing the mould from the injection press.
- - Variants with shut-off even for threaded nozzles, pre-wired systems with shut-off needle adjustment.
