The SD-Severe Duty valve is Copes-Vulcan’s premium severe duty and critical service control valve design.
While virtually identical in outward appearance to the Copes-Vulcan legendarily rugged and dependable D-100 valve line which it replaces, the SD-Severe Duty line is the next generation of control valves designed specifically for severe duty applications. It is the preferred style of valve for applications such as pump recirculation, feedwater control and feedwater start-up, flashing or cavitating service, critical pressure drop gas and steam service, and any potentially noisy or vibration-prone service. It is also widely used for nuclear "N" stamp and seismic applications.
