Severe Duty (SD) Control Valve

SD-Severe Duty 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 of cast construction, all standard castable materials are available. When necessary, due to customer preference or technical requirements, forgings are utilized for both body and bonnet. Depending upon size and pressure class, ends are available as threaded, flanged or welded.
