NEEDLE VALVE SYSTEMS

VALVE GATE SYSTEM

Our valve gate systems for plastic processing are designed for a wide range of applications. That is why we offer you a broad product range with regard to drive types and drive media. The valve gate system offers the following properties and advantages: 

PERFECT INJECTION POINTS

Only a minimal edge imprint of the needle remains when injecting onto visible surfaces. The adjustability of the needle length can be absolutely level with the product surface.

OPTIMUM NEEDLE GUIDANCE

Before immersion in the sealing diameter of the mold insert, the valve gate is centered within the nozzles so that wear on the fitting in the injection mold is avoided.

ADJUSTABLE NEEDLE POSITION

Regardless of the drive medium and the type of drive you choose, the needle position can always be adjusted from the outside without dismantling.

SAFE CLOSING

Whether pneumatic, hydraulic or electric, the drives are basically designed in such a way that it is possible to comfortably close the needles with low pressure/energy expenditure.

HOMOGENEOUS TEMPERATURE AND MELT FLOW

The valve gate nozzles are distinguished by a good temperature profile and homogeneous melt mixing. The needle is supplied from up to four sides to prevent flow shadows.

ADJUSTABLE NEEDLE SEALING ELEMENTS

By means of sealing elements screwed into the manifold system, the needle fitting can be checked and adjusted during maintenance. If the needle fitting is completely worn, this element can be exchanged cost-effectively.

That what is really brilliant, is in actual fact easy.
