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.

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.

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 valves for both compressible and

incompressible fluids.

 Sour Service Capability—Materials are

available for applications handling sour service.

These materials comply with the requirements of

NACE MR0175-2002.

 Long Service Life—Pressure-balanced drive

shaft design with PTFE-lined bearings and

pressure-assisted shaft sealing arrangement

provides for a long life of reliable service.

 Minimum Maintenance—Two-piece ball and

shaft assembly allows for complete trim overhaul;

parts replacement is kept to a minimum.

 Excellent Environmental Capabilities—The

optional live loaded packing system is designed with

very smooth shaft surfaces and live loading to

provide excellent sealing.
