We have component recommendations for these applications. Summer is in full swing, and we are reminded of our customers in the water industry with a specific focus on applications dealing with chlorine or saltwater. Due to the customizable nature of our products, we offer solutions to customers working with these highly corrosive substances. ## Check Valves for Usage in Chlorine For chlorine, our biggest recommendation is to use a specialty plastic body material, such as [PVDF](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/615ee2997c), due to its overall excellent corrosion and chemical resistance. We also recommend a [Viton®](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/96f2e04f83) o-ring option because of its excellent chemical compatibility with this substance. ## Check Valves for Usage in Saltwater Applications Saltwater applications have more flexible component options. We often recommend [Polypropylene](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/15cb1c3376) or [PVDF](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/e59fe6aa4f) for plastics. [Buna-N](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/431a3dd4e5), [EPDM](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/7b8dcb322e), or [Viton®](https://cts.vresp.com/c/?SmartProductsUSA/d0f61b422f/17f44540b4/a93fc89185) are great o-ring options. Please note when working with saltwater, we often find that customers may be concerned about the spring material being compatible with it – especially if the device is intended for long-term use. We offer springs in Stainless Steel, Hastelloy, and Titanium. Stainless steel and saltwater can lead to corrosion over time, but our additional spring materials are available as a solution. In our experience, we have found titanium to be an ideal choice in devices exposed to saline, polluted water, and/or saltwater because it can hold up in highly caustic environments over a longer period of time versus other materials. As always, it is important to discuss all liquids / gasses coming into contact with our valves, as well as application environment and intended shelf-life with us.
