Series 80 Stainless Steel Knife Gate Valves

The Series 80 Stainless Steel Knife Gate valves are designed to deal with chemicals and high temperatures. When corrosion is accruing in your application these valves will work great. We currently offer two different stainless steel valves which serve two different types of applications. The main difference between the two valves is the rubber seat that is bonded to the SSRS valve.
