Design D and DA Control Valves

Product Bulletin Design D and DA Control Valves D and DA Valves Design D and DA single-port, high-pressure valves (figure ) are widely used in oil and gas production industries. These valves are especially useful for either throttling or on/off control of liquids or gases which are gritty, sticky, or which have a tendency to build up on internal valve parts. The Design DA valve is also useful in angle piping or other applications where a self-draining valve is desired. Unless otherwise noted, all NACE references are to NACE MR075-00. Note Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use and maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user. Features Heavy-Duty Construction Massive guiding (figure ) positively aligns the valve plug in the seat ring for high pressure drop applications. The screwed-in seat ring completely encloses the seat ring gasket. Easy Maintenance Screwed bonnet/body joint allows repair or maintenance with a minimum of tools. Severe Service Capability Valve is available with VTC (ceramic) trim for service in very erosive applications. The valve plug is also available with a tungsten carbide tip and the seat ring can be fitted with a full-bore tungsten carbide insert for erosive service. Meets Variety of Specifications Valve body and end connection constructions are available for API as well as ASME standards. W7859- Figure. Design D Valve with Type 657 Actuator NACE Trim Standard NACE trim and bolting materials are standard for all applications. These materials comply with the requirements of NACE MR075-00.
