Feature Highlights

Solid Zirconia Ceramic ComponentsThe disc, liner, stub shaft and stem shroud are all manufactured of solid zirconia ceramic; the flow-path is therefore fully enclosed by ceramic components ensuring exceptional erosion-resistance.

Blowout-Proof StemAn internal stem retention ring ensures the stem cannot blow out if the actuator is removed or if the gland is serviced when the pipeline is under pressure.

Downstream Pipe ProtectionThe valve center line is offset toward the valve inlet; the extended-body therefore absorbs the erosive effects of slurries and prevents downstream pipe erosion.

Zirconia Stem ShroudThe valve stem is completely encased by the unique Z-Max™ zirconia ceramic protective sleeve system to eliminate wear.

Hardened Stainless Steel StemEqual-strength stem and disc connection is designed to reduce stress propagation in the disc. The top of the stem extends into the actuator on most valve sizes to offer precise positioning and control.

PTFE-Encapsulted O-Rings...are durable, resist abrasion, and offer excellent chemical compatibility.

ISO Mounting Pad...is offered as standard, and allows for automation flexibility and compatibility with popular actuators.

Stainless Steel Hardware...resists corrosion and allows for easy maintenance.

Durable, Cast Steel Housing...securely protects the ceramic components and offers increased rigidity and strength. White epoxy coated as standard for corrosion-resistance and for ease of identification.

Position IndicationThe top of the stem features an indicator for quick and easy identification of disc position when installed in the pipeline.

Matching Pipe and Valve BoresThe Z-Max™ bore is manufactured to match standard pipe I.D.’s to avoid disjointed alignment. Matching bores increases valve life and reduces maintenance.

Retention Ring Back-SealingLimited leakage is observed if the stem packing is removed while the pipeline is under pressure.

Serialized ValvesEach valve is individually-serialized and supplied with a riveted nameplate.

Magnesia partially-stabilized zirconia exhibits 2.5 times the fracture toughness of any alumina, nitride, or carbide ceramic. The result? A ceramic valve that resists impact fractures and mechanical failures.

The Z-Max partially-stabilized zirconia ceramic butterfly valve offers significant advantages over conventional butterfly valves:

Erosion ResistantPartially-stabilized zirconia is 12 times more erosion resistant than stainless steel.

Corrosion ResistantCeramics are inherently corrosion-resistant materials, and often at a cost lower than exotic alloy valves.

Cavitation ResistantCeramics are not affected by cavitation, and will therefore not degrade in high differential-pressure applications that are subject to cavitation.

High Differential AbilityThe Z-Max™ valve is designed to operate under full differential pressure in any ANSI Class 150 or Class 300 service - not possible with any other ceramic valve.

Ceramic Properties

Magnesia partially-stabilized zirconia exhibits exceptional transformation toughening properties – which is the material’s ability to prevent existing cracks from propagating through the ceramic. This “self-healing” composition is the most cost-effective ceramic for use in applications that require maximum strength and toughness.

Prime features of zirconia:

• Very high mechanical strength

• Excellent wear, erosion, and abrasion resistance

• Excellent corrosion resistance

• High impact resistance and toughness

• Excellent thermal shock resistance

• Very low thermal conductivity

All Z-Max™ valves are manufactured in an ISO 9001:2008 certified plant
