SD Severe Duty Control Valves
The SD-1000 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-1000 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 startup, 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.
SD style control valve assemblies feature a straight through globe and angle style body design with single web internal construction.
The valve body is designed with high structural integrity, large interior flow passageways and a large capacity bowl to accommodate an extensive variety of trim designs while allowing maximum recovery within the valve.
The massive amount of body and bonnet material utilized and the thick cross sectional areas allow the SD valve to withstand the most severe operational conditions.
The valve is available in sizes .75–20" (20–500mm) and ASME pressure classes 150 through 4500 standard. Larger sizes are available as required.
Typically cast construction, all standard castable materials are available.
Depending upon size and pressure class, ends are available as threaded, flanged or welded.
Copes-Vulcan specialty trims such as Raven™, Hush™, Soft-Seated Hush, Tandem and GAD™ are readily available to meet the most severe applications. All trims are of quick change design to assure ease of maintenance and most are fully interchangeable between like sizes to ensure maximum flexibility and reduced inventory requirements.

General Service Control Valves
Suitable for controlling water, steam, gas and most other fluids, General Service Valves deliver a new standard of versatility, rugged dependability and cost effectiveness. Copes-Vulcan General Service Valves are ideally suited for non-severe flow control of most liquids, steam and gases. They provide reliable, economical performance in heater drains, gas and fuel oil control, feedwater control, steam/gas pressure reduction and many other power and process flow control operations.
Straight-through globe style body design with streamlined precision cast bodies provides smooth contours and transition areas; minimizing flow restriction and maximizing capacity.
Computer calculated cross sections and wall thicknesses assure high structural integrity while maintaining a favorable strength-to-weight ratio.
Available in 0.75–8” (20–200mm) sizes as standard, ANSI pressure classes of 150–600, and most standard castable material choices, with either flanged, welded or threaded end connections.
Can be equipped with an extensive array of standardized trims to meet virtually any general service requirement.
Raven™, HUSH™, Tandem, and GAD™ high-performance trims are available and can be used to control occurrences of cavitation, flashing or noise. All trims are quick change to assure ease of maintenance and are fully interchangeable between like sizes to ensure maximum flexibility and reduced inventory requirements.


A complete range of 700 series pneumatic diaphragm actuators are available.
