Product Introduction
Corrosion resistant valve cores address a failure mode that is distinct from rubber degradation: attack on the metal substrate. In standard valve core constructions, the metal - carbon steel, brass, or aluminum - is exposed at the sealing interface, at fastening features, and along any surface that the rubber layer does not fully cover. In corrosive media, this exposure allows electrochemical corrosion to progress from the metal surface inward, undermining the rubber-metal bond from below and causing delamination and dimensional loss without any degradation of the rubber compound itself.
Our corrosion resistant valve cores address this through two coordinated strategies: corrosion-resistant metal substrate selection, and compound selection for the chemical environment. The result is a component where neither the metal nor the rubber is the failure point.

Processing Techniques and Materials
For highly corrosive environments - strong acids, chloride-rich solutions, oxidizing chemicals - stainless steel or nickel alloy substrates are specified.
For Corrosion Resistant Valve Cores, the rubber compound selection follows the corrosive medium: FKM for acids, solvents, and elevated-temperature chemical service; EPDM for oxidizing aqueous media and ozone-rich environments; HNBR for sour oil and gas streams.
Typical Applications
Typical Applications of Corrosion Resistant Valve Cores include:
· Chemical processing isolation and control valves in acid and alkali service
· Seawater and marine environment valve cores - deck, hull, and subsea
· Desalination plant valve cores - brine and hypochlorite service
· Pulp and paper industry chemical circuit valves
· Water treatment valves in chlorinated or ozonated water systems
Advantages
Designing corrosion resistance into the construction - through substrate selection, adhesive system, and rubber encapsulation - eliminates this failure mode entirely rather than managing its progression.
We select the substrate alloy, adhesive system, and rubber compound as an integrated design for the specific corrosive environment. Technical review of your operating medium and concentration is provided before compound and substrate selection.
FAQ
Q: If I don't know what kind of the product I need, what should I do?
A: Don't worry. You just need to provide us operation conditions such as "working pressure", "temperature" and "media", etc., then, we can suggest the most suitable product to you.
Q: Which industry is your product used for?
A: Our products have been used for multiple industries such as railway transportation, construction machinery, aviation, marine, automobile, etc.
Q: Do you make rubber compound by yourself or do you buy it from others:
A: We make rubber compound by ourselves, with multiple rubber mixing machines in our factory. We can also design the rubber formulation to meet the performance requirement of different applications.
