The Bio-Chem Valve™ Isolation Valves described elsewhere in this
brochure are supplied with threaded ports making them suitable
for installation with standard 1/4”-28 UNF fittings and flexible tubing.
However it is common within modern analytical instruments to use
manifolds instead of tubing and multiple fittings. Custom manifolds
save space and eliminate complicated plumbing inside instruments.
To meet this demand, Bio-Chem Fluidics offers both normally closed
and normally open isolation valves with a manifold mounting
option.
Typically, manifold mounted valves have a threaded collar that
attaches the valve to the manifold. A locating pin ensures the
correct orientation and an elastomer gasket seals the flow path.
Contact your local Bio-Chem Fluidics office for more information and
complete manifold interface details.

Customized Solutions
We understand that many applications require customized solutions. Our design and prototyping expertise enables us to offer
simple modifications of standard products as well as completely customized designs. Many of the Isolation Valves we sell are
customized to one extent or another. Customizable options include (but are not limited to):
•
Materials of construction
•
Mounting options
•
Tagging / labeling
•
Length and/or style of connecting leads
•
Electrical terminations
•
Custom manifolds
We look forward to working with you to meet your design engineering objectives!
The Bio-Chem Fluidics
CoolCube™ “Hit and Hold”
circuit has been used very
successfully with the full
range of Isolation Valves to
reduce opening times. The
CoolCube™ provides the
ability to use a temporary
higher voltage “hit” at the
start of the energizing
cycle. This over-voltage can
significantly reduce the valve
opening time - depending
on the conditions and
voltage applied the opening
time can be reduced by 50% or more.
After 100ms the CoolCube™ automatically reverts to the normal
voltage acting as a fuse to protect the circuitry of the valve. There is
no power storage and the valve turns off immediately when power
is cut to the circuit. The CoolCube™ includes terminal pins for easy
in-line installation.
Availability:
CoolCube™ is available for ALL Isolation Valve configurations. 038T2
Isolation Mini-Valves require the CoolCube-50R, all other sizes use
the CoolCube-R.
