I would like to know the manufacturer of a small, 9mm diameter,
one-way (check) valve. They are commonly found in blood pressure cuff
(sphygmomanometer) squeeze bulbs. Its overall shape resembles a spool
of thread.
It is metal and uses a ball bearing. Look at the photo of the one I
have for reference: photo.net/photodb/photo?photo_id=4724602

Request for Question Clarification by gregaw-ga on 25 Jul 2006 06:14 PDT

There are a lot of companies that make check valves with the ball in
them.  Are you looking for any 9mm ball check valve, or are you
looking for the manufacturer of that specific valve in the picture.


Here are some manufacturers of ball type check valves:

I look forward to hearing your clarification.

Thanks!

Ideally I would like to know the manufacturer of the specific valve in
the picture. However, if you could find the manufacturer of a very
similar valve that is used in a vacuum squeeze bulb (like in a
sphygmomanometer) that would be acceptable. Simplicity and cost
effective design is essential as my company needs to make an initial
order of thousands of such a valve. Most check valves I've found so
far are of higher standard and over-engineered for use in a squeeze
bulb. I need to find something in the price range of $.5 to $.15 per
unit in a large order.

I have increased the price of the question and would like to know the
manufacturer of the specific valve in the picture.
