Due to a supply shortage of Delrin we will temporarily be assembling some valves with ductile iron cages coated with Z-PEX corrosion-resistant coating instead of the standard Delrin cages.

Substituting Z-PEX-Coated Ductile Iron Cages for Delrin Cages
Due to a supply shortage of Delrin, we will be temporarily assembling all new 2" and 3" Diaphragm-Balanced Lever-Operated Dump Valves and Diaphragm-Balanced Pneumatically Operated Dump Valves with ductile iron cages coated with Z-PEX* corrosion-resistant coating instead of the standard Delrin cages. (*This may be shown as “KC” on Kimray codes.)
- 3" Substitution
- Effective Date: 06/07/21
- First S/N Assembled: 2211580571
- 2” Substitution
- Effective Date: 7/12/21
- First S/N Assembled: TBA
Piston Balanced and Piston Balanced Throttling valves will not be affected as they do not contain Delrin standard.
We anticipate no delays in shipments as a result of this change, and there will be no change in price for any of these products.
The Z-PEX-coated cages should perform as good as or better than the Delrin cages. Based on the current information from our suppliers, we estimate that we will be able to start using Delrin again in Q4 2021.
Each product with this substitution will be clearly marked on the box and product tag.

How Z-PEX Works
Z-PEX electro-deposits a hybrid poly-epoxide coating over a zirconium oxide pretreated surface. This process creates a chemical-resistant base coat that forms an electro-molecular bond with the substrate.
Following that base coat, a fluoropolymer topcoat is spray applied to the wet surfaces and/or threads of the units and baked, creating a permanent crosslink of the epoxy and fluoropolymer coatings.
