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. As the ball closes, this V-notch creates a shearing effect, minimizing particle adhesion. This design makes it particularly suitable for handling erosive or viscous fluids, pulp, or other slurry fluids containing mixed solids or fibers. The V-notch ball has been specially contoured to increase capacity and enhance seal life and shutoff integrity.

Butterfly valves are a type of rotary valve that use a rotating disk to control flow through a pipe. The disk is generally operable through 90 degrees and provides a linear flow characteristic. For throttling control applications, one type of butterfly valve is now the industry standard: high performance butterfly valves (HPBVs) or double offset valves. Their advantages include a straight-through flow path, very high capacity, and ability to pass solids and viscous media. High performance butterfly control valves are intended for general service applications not requiring precision throttling control.

A desuperheater injects a controlled, predetermined amount of water into a steam flow to lower the temperature of the steam. To achieve this efficiently, the desuperheater must be designed and selected correctly for the application. Although it can appear simplistic in design, the desuperheater must integrate with a wide variety of complex thermal and flow dynamic variables to be effective. Steam conditioning valves control steam pressure and temperature by combining both functions within one integral control unit. These valves address the need for better control of steam conditions brought on by increased energy costs and more rigorous plant operation. Steam conditioning valves also provide better temperature control, improved noise abatement, and require fewer piping and installation restrictions than the equivalent desuperheater. Fisher offers different styles of desuperheaters that can be combined with control valves to form a desuperheating and depressurization system, effectively reduce the temperature of superheated steam to the desired set point.

Level-Trol Controllers are designed to utilize Archimedes' principle to measure liquid level, liquid interface level or changes in density/specific gravity in process vessels. The design ensures high accuracy, easy of installation and adjustment, making it a reliable solution for critical applications. These products are proven in different applications including power, chemical process, oil and gas, and the petrochemical industries.

Severe service control valves are used in extremely challenging severe service control valve installations in process plants that commonly include cavitation, erosive, corrosive, noisy, high pressure, high temperature, high pressure drop, or high velocity media. In order to extend equipment life under these severe service conditions, these control valves typically utilize extremely hard materials capable of withstanding extreme temperatures and pressures. valve bodies with special flow paths, high capacity valve cavities, and cages with unique flow passages. Fisher offers a diverse range of special valves for severe service applications to address the customer's on-site needs.
