Corrosion resistant cartridge models including stainless steel hex body, titanium or brass adjust screw, are designated by /AP appended to the standard model code. Complementing already available corrosion resistant valves, Sun Hydraulics now offers zinc-nickel plating on an initial selection of cartridge valves. Zinc-nickel cartridge models are designated by /LH appended to the standard model code. (Corrosion resistant models were previously depicted with a P for Buna-N and W for Viton in the 7th position of the model code.) New codes will be developed as new material/coating choices are made available.

Below is an example of the model code structure:
