Fisher Vee-Ball Control Valve:

The Fisher Vee-Ball valve with its
V-notch ball provides positive
shearing action and a nearly equal
percentage flow characteristic. It
provides non-clogging, high-capacity
flow control of gas, steam, clean
and dirty fluids, abrasive chemicals,
and fibrous slurries. You will find
this valve hard at work in the pulp
and paper, power, chemical, and
petrochemical industries.

components work together, delivering superior dynamic

performance and low operating cost.

Easy Installation

To reduce installation time and
headaches, the Vee-Ball rotary
control valve is available with
either a flangeless ANSI body or
an integral flange body. The
flangeless design uses integral
centering lugs to help simplify
alignment procedures.

Money and Time-Saving Benefits

Regardless of the application, incorporating the Fisher
Vee-Ball valve into your process can have significant
money and time-saving benefits:

•

Improve Total Cost of Ownership - Quality Fisher construction

enables long-term performance from your Vee-Ball valve.

•

Reduce Process Variability - The Vee-Ball rotary control valve

is a highly engineered component essential to the accuracy
and controllability of your flow system. Extensive flow loop
testing has demonstrated the Vee-Ball valve’s low friction
performance advantage in controlling process variability.

•

Reduce Downtime - The rugged Vee-Ball valve incorporates

large margins of safety in its design. This, coupled with
extensive flow testing and evaluation, results in a rotary
control valve that is the industry standard for reliability.

•

Improve Operational Efficiency - The Vee-Ball valve’s high

capacity and excellent characteristics mean your process can
be controlled with less system pressure drop across the
control valve.

•

Reduce Parts Inventory - Commonality of parts across the

Vee-Ball line helps you trim inventory costs to a minimum,
resulting in bottom-line savings.

•

Reduce Maintenance Costs - The V-notch ball seal can be

replaced without valve disassembly or actuator removal.

•

Reduce Training Costs - The Vee-Ball valve meets the

requirements of a broad range of applications, which means
engineering and maintenance training can focus on a single
valve design. Your staff can quickly take advantage of the
Vee-Ball valve’s flexibility, saving training time and expense.

•
