Chemvalve 880S-150 Check Valve

ChemValve Model 880S-150 is a spring-assisted, fully lined ball check valve designed to prevent backflow in aggressive chemical service. The valve's rugged construction pairs a ductile iron body with a solid PTFE ball and a Hastelloy C-276 spring, secured with Grade 5 alloy steel bolting, and it is rated ANSI Class 150 for downstream piping. As part of ChemValve's fully lined ball-check family (which includes 880-150, 880S-150, and 880S-300), the 880S-150 can be paired with a range of chemically compatible liners to tailor resistance to specific media while preserving tight shut-off. Typical applications include water demineralization and ion-exchange process loops and other chemical processing lines where backflow prevention is critical, with the valve offering inline installation and maintenance-friendly features designed for long service life in corrosive environments. ChemValve's design emphasizes reliability in fluctuating flow or pressure conditions through its spring-assisted mechanism, which helps ensure quick reseating and minimizes the risk of reverse flow in demanding plant layouts.
