Check Valves
Check valves help guard against plugged tips, over-pressurizing
or incorrect startup procedures. Their ball valves
are held open by gas pressure, and if the gas pressure
stops or reverses, the ball seats and shuts off the flow.
(Note: Check Valves cannot stop a fast-moving explosive
pulse but can be used with flashback arrestors for
additional safety.) A-size. Mounts to torch to prevent reverse
flow at point of origin.

Flashback Arrestors
Flashback arrestors are designed to help prevent serious
accidents caused by reverse gas flows or “flashbacks”
and can help to prevent ignition of mixed gases.
Their price reflects the increased safety over simple
check valves. Available in regulator or torch models
(see photo). sold in pairs – 1 oxygen + 1 fuel gas.
