Benefits of using knife-gate valves in wastewater pipeline systems

In wastewater applications there are several reasons for using stainless steel for components critical to proper function and thus ensure the long-term reliable function of a valve: Each time the valve is opened, the knife itself is cleaned by two scraper profiles integrated on both sides. These scrapers reduce unnecessary maintenance work, thus saving time and money.

An important issue in the wastewater sector is the problem of corrosion. Knife-gate valves having a knife made of stainless steel make the valve less susceptible to damage by corrosion caused by the medium and thus have to be serviced or replaced less frequently. Corrosion is not only the cause of more frequent maintenance intervals, but also involves a permanent failure risk of the valve as it prevents the valve from closing properly.
