- A valve that closes to prevent backward flow of liquid
- A check valve, clack valve, non-return valve or one-way valve is a
mechanical device, a valve, which normally allows fluid (liquid or gas) to flow
through it in only one direction.
- A valve which will allow water to pass in one direction but will close and
prevent flow (backflow) in the opposite direction.
- Limits the flow of gas to one direction only. Use a check valve between the
bubbler and generator to prevent unwanted pressure build up in the generator,
and a safety against a low level bubbler. A check valve, such as used on
torches, is recommended.

bO's advise pays off. My 1990 Trooper's check
engine light has been coming on intermittently which made me nervous about
getting it smogged. bO had mentioned Auto Experts on Higuera St. behind Mission
Thrift Store and their reputation for giving older vehicles a few extra tweaks
and nudges to help them through the smog check. So I disconnected the battery to
clear the "Check Engine" codes (which doesn't really work), drove the Trooper
down to get smogged and crossed my fingers. An issue came up during the test and
Paco looked around and found an old, brittle vacuum hose on the EGR valve and
replaced it with no charge. Some shops would have just said, "Your car failed.
It will cost 3 million dollars to fix and we'll have to charge you for a second
smog check." Not Auto Experts! Thanks bO. Thanks Auto Experts 540 Higuera SLO,

hoses and plumbing lines of liquid oxygen carts here are in good condition. The
mission of the electro and environmental technicians is to inspect, calibrate,
repair and maintain cryogenic/compressed gas units here. They discharge,
calibrate, repair and leak test all carbon dioxide life raft inflation and small
