The inventor of Zeiger's Z4TM 4-piece*
now innovates with an affordable best-in-class 3-piece.

You've always known the Zeiger 4-piece non-return valve as the gold standard of injection molding valves, but maybe didn't need that premier degree of performance and longevity. Now, Zeiger engineering - the same design experts with the same manufacturing technologies - introduces the first advanced 3-piece screw-tip valve for better, more affordable performance made specifically for general injection molding operations.

self-cleaning convenience/efficiency: full-flow, self-scrubbing channels

easy maintenance with standard tools: fast-installing hex wrenching flats

accuracy and repeatability: excellent shot-to-shot control
