Fisher® Vee-Ball™ V150

Vee-Ball™ V150 is a flanged valve for throttling or on-off operation for many different applications in the process industries. The V150 is available in NPS 1 through 20, CL150 (DN 25 through 300, PN 10/16). Trim components are interchangeable between Design V150, V200 and V300.

• Trim Versatility—Trim components are interchangeable between V150, V200, and V300 valves. This feature allows you to reduce your spare parts inventory and maintenance procedures. The seal assembly can be changed without removing the actuator or without removing the ball from the valve body.

• Easy Installation—Flanged body design of the V150 and V300 eliminates exposed line flange bolting, reduces alignment and installation time, and promotes secure valve installations and piping integrity.

• Application Versatility—The valves are available with ISA S75.04 and IEC 534-3-2 face-to-face dimensions as a standard construction, and optional ASME B16.10 short face-to-face dimensions. IEC 534.3.2 face-to-face dimensions are equivalent to S75.04 face-to-face dimensions.

• Long Service Life—The solid HD metal seal construction provides long service life in demanding applications. The constant wiping action of the seal across the ball's sealing surface prevents scale and sludge buildup, and provides excellent service on steam, gases, slurries, and various liquid applications.

• Smooth Valve Operation—Precision machined parts and pressure balanced seal designs allow smooth, precise movement of the ball.

• Excellent Flow Control—Precise contouring of the Vee-Ball provides a modified equal percentage flow characteristic. For very precise control of low flow rates, the Micro-Notch option is available on the NPS 1 valve. See the Micro-Notch Construction section of this bulletin for more information.

• Sour Service Capability—Materials are available for applications handling sour service. These materials comply with the requirements of NACE MR0175-2002.

• Quick and Easy Maintenance—Ball seal inspection and replacement is done at the valve body inlet without removing the actuator or disassembling the valve. Valve maintenance requires no special tools.

• Structural Integrity—One-piece valve body improves structural integrity of the pressure boundary by eliminating leak paths that could be caused by the gaskets in two-piece, bolted valve designs.

• Exceptional Environmental Capabilities—The optional ENVIRO-SEAL packing systems are designed with very smooth shaft surfaces and live loading to provide exceptional sealing. The seal of the ENVIRO-SEAL system can restrict emissions to less than the EPA (Environmental Protection Agency) limit of 100 ppm (parts per million).
