The Retainer of the Z4 4-piece screw-tip valve features 17-4PH stainless steel plus a LIFETIME WARRANTY.

Steely Don

The mission: Make the gold standard of screw-tips.
The enemy: Battle heat, corrosion, and abrasion.
The secret weapon: The valve of a lifetime.

Don Zeiger took the enemy head-on with superior steel and steely determination. He challenged himself to make something unbeatable now... unbeatable next year... unbeatable forever. The forever part's important, because this gives the Z4 something no one else has, a Lifetime Warranty on the Retainer.

The Z4 4-piece is fighter-jet tough to give you the stuff of victory. When you think of fighter jets, right away you're thinking of tough conditions and rough challenges. Don chose to go all the way with 17-4PH steel for the oh-so-important Retainer portion of his injection molding gold standard.

It's wuss-prof and wimp-protected. It gives you nerves of steel for the most demanding applications because it carries a no-small-print, no-questions-asked Lifetime Warranty.

The other guys don't have those nerves of steel, but they sure has some nerve - because the so-called "competition" continue to pass off lesser steels or nitride-coated steel that's just a sorry substitute and a cheap veneer compared to the Z4.

Here's the Retainer explainer:

The Z4 is infinitely adjustable for specialty resins, applications, and process improvement at no cost to the customer. Better steel and better processing makes for the ultimate performance under the most demanding injection molding circumstances.

  • this is the core of the valve assembly, and it's made with 100% heat-corrosion and abrasion-resistant steel
  • hardened 17-4PH (17% chrome and 4% nickel) stainless steel
  • landing gear strength (like what's used on the landing gear of F-15 fighters)
  • lasts longer for lower life cycle costs and lower downtime ordinarily brought on by premature failure of ordinary valves or valve assembly
Don welcomes tough conditions and rough challenges.

Bring on the heat!

Don't hold back with those abrasives and impurities!

Take your best shot and go crazy changing materials and colors and viscosities!

Because Don Zeiger invented the 4-piece valve, he wanted it to be the best performing valve in the injection molding industry. So he uses a different steel for each part of the valve, the right steel for the right component - based on the optimum operational purpose in the valve assembly.

Don's Never Never Land

  Never Never No. 1  

nitriding is like putting lipstick on a pig!

Nitriding is a cheap trick using a cheap veneer. The coating falsely raises the Rockwell rating, so your valve can be damaged beyond repair in two weeks! Don will NEVER nitride, ALWAYS using the right steel hardened right instead. LEARN HOW YOU CAN DECREASE DEFECTS

Is a free-flow valve really free flowing?

We don't think so. Free-flow valves actually make a mess with burnt material left behind after each shot. Leakage. Labor. Downtime. Don will NEVER sell a free-flow and will ALWAYS use a full-flow valve instead. LEARN WHY OURS IS THE INDUSTRY STANDARD
