www.F D 10 00 53 X 01 2 Design V250 Rotary Control Valve The Design V250 Hi-Ball rotary control valve (figure 1) is designed for heavy-duty throttling and on-off applications. Depending on size, this valve installs between two CL600 or CL900 pipeline flanges. The Design V250 valve is available with a single ball seal, flow ring, or dual-seal construction. Single-seal constructions are used in tight shutoff applications; the flow ring construction can satisfy higher temperature requirements. The dual-seal construction, with a seal in the inlet and outlet openings, is used in bidirectional flow-shutoff applications. The Design V250 Hi-Ball valve is typically used for throttling and controlled flow applications in gas transmission lines, gas distribution, or liquid pipelines. 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 High Pressure Drop Capabilities—Depending on the construction, a Design V250 valve is capable of a maximum static pressure differential of 103 bar (1500 psi) at 82°C (180°F) for CL600, and 155 bar (2250 psi) for CL900 constructions at 38°C (100°F) for LCC steel and CF8M (316 stainless steel). Efficient Operation—Tapered-polygon ball-to-shaft connection (see figure 5) and clamped splined actuator connection (see figure 6) remove lost motion or deadband from the drive train for throttling control applications. Excellent Flow Control—Reduced ball port design provides a modified equal percentage flow characteristic and an excellent response characteristic. W4177 / IL Figure 1. Design V250 Valve with Type 1061 Actuator Tight Shutoff—Shutoff with the Design V250 ball seal is 0.0001 percent of maximum capacity. Greater Capacities—Design V250 ball valve construction offers greater capacities than conventional globe
