Innovative
Balanced Plug Design: Balanced Plug technology lowers the force
required to operate the valve, achieving exceptionally high
close-off of 125 psi on 2-way valves. This is up to 7 times
higher than conventional valve designs, even in the most
demanding applications. Instead of pushing against the water
flow as in conventional designs, the new Patented Balanced Plug,
with 90% less surface area than conventional valves, cuts
through the water. This greatly reduces the force required top
operate and close the valve.
Higher close-offs
are achieved without bulky, costly actuators or tandem linkages.
In addition, no expensive balancing chambers or double seals are
required. This permits more actuator options, particularly on
5” and 6” valves. With less force required to operate the
valve, actuator life is extended. A downloadable demonstration
of the Balanced Plug Technology can be found in the More
Information section of this page.
Patented Plug and
Seat Contour: The patented contoured seat precisely controls the
flow of water or steam as the plug slides, closing off the rim
of the seat. The VB-8000 Balanced Plug Valve provides
rangeability of 100:1 for more precise temperature control. Many
competitors’ valves have rangeability of 50:1 or even 10:1,
which provides only ½ to 1/10 of the control capability
of the VB-8000, resulting in poor control. More precise control,
especially at low demand, provides better comfort. It also
reduces “hunting” that adds wear and tear on the actuator.
Industry Best ANSI
IV Leakage Rating: TAC Balanced Plug VB-8000 valves feature ANSI
Class IV leakage. That’s 0.01% leakage. Most valves of this
size have 0.5% or even 0.1% leakage. The increased leakage of
competitors’’ valves means that more fluid needs to be
conditioned, resulting in greater operating costs. With
today’s energy prices, the valve can pay for itself in as
little as 3 years.
Unique 3-Way
Design: The 3-way VB-8000 valve can be used in mixing,
diverting, and 2-way angle valve applications if either side
port is sealed off. That’s because the common “AB” port is
on the bottom of the valve. A plate showing the correct piping
is installed on all 3-way valves to assist contractors in the
field. A common 3-way valve makes valve selection easier and
stock inventory of spares can be reduced.
