New Clippard DV Series
High Flow In A Miniature
Clippard’s entry into the miniature electronic
valve market began in 1973, when Leonard
Clippard, founder, introduced the EV line of
valves which utilized only one moving part,
the “spider”. Today, the EV valve is still serving a very horizontal market with thousands
of installed applications in a multitude of industries. Since the initial introduction, several
new series have been added to the line, including; Corrosion-Resistant, Oxygen Clean,
Analytical, Proportional Control, Intrinsically
Safe, EM/ES series, all utilizing the “spider”
design. Enter the New DV valve.
New Design Challenges
According to Dave McBreen, the DV valve
Design Engineer at Clippard, the all-new design began with the coil. “It’s not that we designed the valve around the coil, but we knew
our design parameters called for the coil to be
less than 2.0 watts, so we began there. The
process for determining the correct coil was
enhanced by a coil calculator which was designed by Clippard’s own Engineering department.
Once he had the design criteria, McBreen felt
as though his biggest challenge was to con-
sider the manufacturing processes and the
need to get the product out the door. How to
get a cost-effective, optimized design through
manufacturing and yet be fairly simple to as-
semble. Yet, he had other criteria to consider,
including size, power, flow, pressure and ma-
The all stainless housing provides many envi-
ronmental advantages along with delivering a
very robust package. “It can be taken apart
and put back together in seconds,” said
McBreen. One of the main reasons for this is
that the valve only has one moving part…the
The all new stainless steel spi-
der is capable of flows to 100
l/min at 100 psig. With a pre-
load of approximately 0.017”,
stroke up to 0.018”, and re-
sponse time of 10-15 milliseconds, the DV
Series can be utilized in many applications.
And, with the over-molded seal, the valve will
continue the high standard set by the industry
leading EV line for leak-free operation, which
is particularly meaningful for analytical appli-
Another feature not readily found in other
miniature valves: bi-directional flow. It is designed to serve as a dual flow valve within a
certain pressure range.
The series is offered with various orifice sizes,
mounting styles and voltage options, and is
highly modifiable for specific applications.
The DV line is assembled in Clippard’s
Cincinnati, Ohio plant where there is capacity
to produce and test thousands of valves per
week due in no small part to the straight-for-ward design.
Where will the valve be used? According to
Rob Clippard, Vice President of Sales & Mar-
keting, “One of the key applications will be
in the medical field. Although there are nu-
merous applications within the medical indus-
try, none will be more applicable for this valve
than blood pressure cuffs. Additionally, appli-
cations requiring some sort of pressure mon-
itoring, pulse monitoring of the heart or
perhaps oxygen therapy have a great amount
of potential. With its high flow capability, res-
pirator applications will definitely be one of
the most common uses. Other applications in
the medical field would include ventilator and
kidney dialysis machines”.
Yes, medical will be a primary focus however
there are many other applications and markets,
including gas chromatography, liquid chro-matography/mass spectrometry, and other applications requiring analysis. Clippard noted
the valves would be used throughout the packaging industry, especially where small banks of
manifold-mounted valves would be needed.
So, what’s ahead for the DV valve? According
to John Campbell, President, “This is one of
the new generational valves, and we believe it
will contribute to the success of the company
for a long time. From this basic design, we expect to be successful from the start; we’ll be
growing into many other products as we continue to invest in engineering and new product
development as critical keys to our future”.
