Zeiger Industries has engineered exceptional valves for unique applications with the Z4 4-piece screw-tip valve*.

The Z4 goes Xtreme!

Extreme conditions and critical applications need special attention and specialized components. Other screw-tip manufacturers can barely get by with a valve that won't fail a couple of weeks out of the box in regular conditions, let alone try to handle the harsher stuff.

Already The Ultimate for Demanding Performance, the Zeiger Z4 also gives you a great range of options for the most critical of applications where product performance is paramount. Our "no compromises" special engineered valves include:

• Spinner Valve
  
  
  • for high speed injection molding situations (non-filled resins)
  • as the name suggests, the Spinner Valve is designed to rotate in the barrel
  • this spinning reduces the heat normally caused by friction associated with an ordinary, non-rotating/stationary valve
  • predictably, as good as this is, the original Zpringlok was bound to attract some imitators: "Plasti-Co's 'Spin-Lock' 3-piece interlock sure sounds a lot like our spinner!"
    
• Zpringlok Valve
  
  
  • for low viscosity materials use
    
    
  • a special spring is inside the valve itself
    
    
  • this design is superior to any design based on a spring on the outside of the valve ("That's just useless," warns Don.)
    
    
  • retrofits any OEM screw with no needed customizations to fit the OEM envelope
    
• EXCLUSIVE: Tungsten-Carbide-Faced Valve
  
  
  • for the longest life possible, even in the toughest conditions
    
    
  • Lifetime Warranty states that this valve will outlast the injection molding machine itself
    
    
  • Don's particularly proud of this, the ultimate of the ultimate: "No one has ever worn out this valve! Ever!"
    
    
  • Germany's DeMag buys only this 4-piece carbine-faced screw-tip for their most severe customer requirements

Zeiger Z4 zaps all the rest! Never again settle for 4th rate 4-piece wannabes or substitutions by 3-piece pretenders!

Zeiger invented the 4-piece.

Zeiger re-invented the non-return screw-tip.

And Zeiger invented the full-flow valve.

So he can invent a custom solution for any situation.

Because Zeiger Industries is based around engineering original injection molding innovations instead of just back-engineering other people's ideas (unfortunately the case for most of the rest of the industry), custom designs are a natural.

Don Zeiger knows that there are plenty of applications requiring distinct design differences and is glad to accommodate with application-specific versatility. Zeiger will custom design any valve for any need and meet the challenge for any application. He gladly repeats his promise, "Tell me what you mold, and I will tell you what you need."

No matter what, Don Zeiger doesn't settle for anything less than what's necessary for an injection molding valve application. Neither should you. The Z4 is infinitely adjustable for specialty resins, applications, and process improvement at no cost to the customer.
