Valve Gate systems, designed with robust and compact cylinders, offer superior performance and gate quality with both hydraulic and pneumatic actuation available on DF GOLD systems. Pneumatic valve gates are available on QF5 and QF8 systems.

Direct Mount Units
Actuation cylinders mount directly onto the manifold making it unnecessary to remove the valve pins before removing the entire system from the mold. Valve pin adjustment is simply accomplished without hot runner system dis-assembly.   

Integrated Compact Design
The direct mount feature also allows INCOE® DFQ hydraulic Valve Gate systems to be supplied as a completely self-contained unit, both pre-plumbed and pre-wired.

Clean Room Ready

Pneumatic DF/QF Valve Gate systems are ideal for clean room molding applications such as medical disposables.  Zero gate vestige and pneumatic actuation allows consistent and rapid closing of the valve pin, complimenting part weight and dimension requirements.

Nozzle Design
DF GOLD Systems can utilize either our threaded DFQ series of nozzles, or our compression fit DFX nozzles.

The Quick-Flo™ (QF) nozzle design utilizes a compression fit onto the manifold. The mold retainer and back plates secure the entire system into the injection half.

Shot Weights
6 nozzle sizes process from <5g up to 5900g shot weights. Nozzles are identified by runner/ channel sized in mm as follows:

Quick-Flo™ Shot Weights
2 nozzle types processing between 7-375g shot weights. Nozzles are identified by runner/ channel sized in mm as follows:

Valve Gate Performance Features:
•    Zero gate vestige
•    Cycle time reduction by fast filling and only partial use of hold pressure
•    Elimination of freezing, stringing or drooling of gates at start up or interruptions
•    Lower melt stress and low part distortion
•    Elimination of weld lines when used with Gate Sequence Control (GSC2) or
(VGC). DF Gold systems only.
•    Elimination of wrinkles in substrate in back-molding applications with GSC2. DF Gold systems only.
•    Balanced filling of different size parts in family molds

And is ideal in the following industries / applications:
