Testing

Research and Development activities are conducted in our state-of-the-art technical center in Sartell, Minnesota. High Performance Butterfly Valves. AWWA Butterfly Valves. Eccentric Plug Valves. V-Port Ball Valves. Rotary Control Valves. Knife Gate Valves. No matter the valve, or the industry it serves, every DeZURIK product undergoes a stringent set of tests. Capabilities include high and low pressure flow loop testing for verification of capacity, characteristics, product performance, and noise levels. The computer data acquisition center captures the test parameters and results.
