NBVメタルタッチボールバルブの特徴
使用範囲、耐久性、開閉トルクなど、総合力なら、NBVメタルタッチボールバルブ。
For overall strength, including range of use, durability, and open/close torque, NBV’s metal touch ball valves are the best possible choice.
The high sealing ability and low resistance to passing
fluid of ball valves means that they are commonly used
in a range of industrial plant piping. A ball valve’s sealing
ability is maintained by a ball and seats that hold it at
both ends, which are typically constructed from resin and
known as soft seats.
The distinctive feature of NBV’s ball valves is their metal
touch, meaning that both the ball and the seats are
made of metal. As they are made only of metal, our ball
valves are a clear departure from typical ball valves,
and exhibit a number of superior features. Just some of
the characteristics only found in metal touch ball valves
are the ability to deal with high temperature and high
pressure conditions or highly abrasive fluids such as
slurries, pellets, and powders, and such performance is
beyond the scope of soft seat ball valves. Using metal
touch requires the use of advanced technology, such as
high precision lapping and adhesion between the ball and
seats, as well as preventing seizing.
In 1965, NBV successfully developed technology for
performing high precision polishing processing and
hardening treatment as well as developing a new contact
mechanism and launching our metal touch ball valve. This
development has not stopped as we continue to work on
developing our technology in response to our customers’
stringent demands.
Our ball valves can be used under high temperature
and high pressure conditions unsuitable for soft seat
ball valves, as well as with all kinds of fluids, including
slurries, pellets, and powders.
Reliable durability
The metal ball and seat are connected using a disc spring.
As fluid only causes minimal damage to the contact parts,
durability is high and the valve can be used reliably over
long periods.
Sealing ability and stable open/close torque
The elastic force from a disc spring connects the ball and
seat and provides a consistently high sealing capability.
The disc spring also follows thermal expansion arising
from temperature changes, allowing a stable open/close
torque to be maintained.
Other structural features
The valve’s body is an integrated casting that encloses
the ball and is capable of withstanding high internal and
external pressure. This also allows for easy production of
multi-way valves such as 3-way, 4-way, and 5-way valves,
or jacketed valves.
With their combination of ball and seats, metal touch ball
valves require extremely high precision in the ball and its
sphericity and in the surface of the seats to maintain the
seal. NBV’s ball valves are polished to an extremely high
precision with a ball out-of-roundness of less than 5/1000
mm, while the elastic force of the disc spring provides
correct surface pressure, ensuring an unparalleled sealing
ability.

NBVメタルタッチボールバルブの標準用と高温用の違い
Differences between standard and heat resistant NBV metal touch ball valves
200℃までの標準用、800℃までの高温用で異なるメタルタッチボールバルブの性能。
Performance differs between our standard (for use up to 200ºC) and heat resistant (for use up to 800ºC) metal touch ball valves.
We produce two types of metal touch ball valves, classified by
temperature.
Standard (O-ring type) Room temperature to 200ºC
★
Heat resistant 200 ºC to 600ºC (Tested at approximately 800ºC)
★
The valves’ seat rings are metal and can therefore be used
under high temperatures, but limitations do arise due to the
sealing method.
Sealing ability in our standard valves is ensured by the
insertion of an O-ring between the outer circumference of the
seat ring and the inner surface of the body (see Figure below).
O-rings cannot be used in high temperature conditions,
however, which led us to use gland packing (or a metal seal
ring).
The increase in torque in a high temperature environment due
to thermal expansion can lead to the valve malfunctioning.
NBV’s products, however, are constructed following calculation
of thermal expansion coefficients, and the tightening force of
the disc spring – which responds to temperature – ensures the
valve’s seamless operation.

NBV’s original valve structure since
establishment, this valve is capable of forming
a seal when pressure is applied from either left
or right (bi-directional type). Disc spring force is
adjustable, allowing the valve to display stable
performance under a range of conditions. Our
standard type valve is also suitable for use in
conditions requiring abrasion resistance, such
as highly abrasive powders and slurries, which
are difficult to handle using a PTFE seat.
This valve’s compatibility is underscored
by its face-to-face dimensions and other
measurements being identical to standard
ball valve dimensions. Unlike our 102F-type,
disc spring force is not adjustable, but this bidirectional type is fully capable of handling
ordinary powders and gases.
With the same basic shape as the 102F-type, this
bi-directional type valve uses gland packing in
place of an O-ring as the seal material. Can be
used with high temperature fluids over 200 ºC.
The [A] type valve joins our existing 102F-Htype lineup, further increasing NBV products’
reliability in high temperature conditions.
This valve’s compatibility is underscored
by its face-to-face dimensions and other
measurements being identical to standard ball
valve dimensions. Unlike our 102F-type, disc
spring force is not adjustable, but the valve’s
structure is kept simple by not using an O-ring.
Pressure direction is limited to one direction.
This valve can be used with high temperature
fluids over 200 ºC.
This valve can be used to switch a fluid’s flow
path, and both T-port and L-port circuits can
be selected. Can be used with highly viscous
and high pressure fluids, which are difficult to
handle using a PTFE seat.
Examples of use: Gases, exhaust fumes,
powders, polymers, and slurries, etc.

Features
Continuous seal struc ture
Constant contact between the seat and drum ensures
burst-type leaks cannot physically occur. This prevents
any pressurized air loss, allowing stable supply
and discharge and makes our drum feeder ideal for
conveying high-pressure and high-concentration
materials.
Sharp e dge prevents jamming
The drum opening has a V-cut part, which splits fluids
with a sharp scissor-like shearing force, ensuring that
any impact and abrasion does not affect other parts.
Even if the slide seal surface is worn the amount of
leakage is stable
The seat ring is supported by a spring that follows the
drum if wear accelerates, ensuring the drum feeder’s
sealing ability.
Difficult to crush par ticulate materials
The drum feeder performs a closing action in every
rotation, which reduces the probability of crushing due
to jamming and helps maintain particle shape.
Prevents scoring and seizing
The drum feeder’s metal sliding parts are subject to an
established surface hardening process used with metal
touch ball valves. This improves abrasion resistance,
prevents seizing and scoring, and maintains the feeder’s
extremely high durability.
Easy Adjustment of Seating force
The seat ring’s compressive force,which is optimally
suited to the nature of the fluid and the function of the
equipment, can be adjusted while still installed in the
pipe.
Quantification through adjusting feed amount
The feed amount can be controlled by adjusting the
speed of rotation using the inverter control. The feeder
also uses the drum (bucket) method to ensure a stable
and highly-precise quantitative capability.
