Fisher Vee-Ball™ V300 Flanged Control Valve

The Fisher Vee-Ball V300 Flanged control valve is your best choice for performance and cost-effectiveness across a broad range of applications. The precision-machined parts and pressure-balanced seal designs allow smooth, precise valve operation.

What is a Segmented Ball Valve?

A segmented ball valve is similar to a conventional ball valve, but with a contoured V-notch segment in the ball. This control valve has good rangeability, control, and shutoff capability. The V-notch ball provides positive shearing action and produces an inherent equal percentage flow characteristic. It provides non-clogging, high capacity flow control. The V-notch ball has been specially contoured to maximize capacity and enhance seal life and shutoff integrity.

Common Applications

V-notch ball control valve bodies are suited to control erosive or viscous fluids, paper stock, or other slurries containing entrained solids or fibers. The paper industry, chemical plants, sewage treatment plants, the power industry, and petroleum refineries use such valve designs.

Features

  • Flanged body design eliminates exposed line flange bolting, reduces alignment and installation time, and promotes secure valve installations and piping integrity.
  • The solid HD ball seal construction provides long service life in demanding applications.
  • Precise contouring of the Vee-Ball provides a modified equal percentage flow characteristic.
  • Materials are available for applications involving sour liquids and gases. These constructions comply with NACE MR0175-2002, MR0175-2003, MR0103, and MR0175/ISO 15156.
  • Ball seal inspection and replacement are done at the valve body inlet, without removing the actuator or disassembling the valve.
  • The one-piece valve body improves the structural integrity of the pressure boundary by eliminating leak paths that could be caused by the gaskets in the two-piece, bolted valve designs.
  • The optional ENVIRO-SEAL™ packing systems are designed with very smooth shaft surfaces and live loading to provide exceptional sealing.
