As industrial processes continue to increase in complexity and risk, valve design and performance is crucial to maintaining consistent plant operation and maintaining your bottom line. Valves are critical to protecting your workers and the environment; they need to be reliable in the harshest of conditions.
CGIS’ DSS Valves is known for creating dependable Severe Service Valves that outlast the competition in any scenario. The preeminent Severe Service Knife Gate Valves (SSKGVs), made entirely in North America.
