Fisher V250 Full Bore Pipeline Ball Valve – Rotary Valves

Product Overview

Fisher V250 Valve is a full bore pipeline ball valve designed for heavy-duty throttling and on-off applications. The V250 valve is available with a single ball seal, flow ring, or dual-seal construction and depending on the size of the application the valve can be installed between CL600 or CL900 pipeline flanges.

The single seal construction of the V250 valve is used for tight shutoff applications and the double seal construction is used in bidirectional flow-shutoff applications.

The design of the Fisher V250 is typically used for applications in gas transmission lines, gas distribution, or liquid pipelines.

Fisher V250 Full Bore Pipeline Ball Valve – Product 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 and clamped splined actuator connection 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
• 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

Installing Fisher V250 Full Bore Pipeline Ball Valve

Fisher V250 full bore pipeline ball valve may be installed in any position. However, the recommended orientation is in a horizontal pipeline with the shaft positioned horizontally and the ball closing in the downward direction.
