0690-0032 - Victor CTO Oxygen Torch Check Valve 0690-0032

Reliable Reverse Flow Protection for Industrial Safety

The Victor 0690-0032 CTO Check Valve is a critical safety component designed for professional oxy-fuel cutting and welding operations. Engineered by Victor, a global leader in gas equipment, this check valve is specifically calibrated for use with Oxygen gas lines. Its primary function is to prevent the reverse flow of gases from the torch back into the hose, a dangerous condition that can lead to the mixing of fuel and oxygen within the supply line. Such mixtures are highly volatile and can result in catastrophic equipment failure or injury. By installing the CTO check valve at the torch inlet, operators ensure that gas flows in only one direction—towards the tip.

Robust Construction and Compatibility

Manufactured in Mexico to Victor's stringent quality standards, this check valve features a durable brass body capable of withstanding the rigors of daily industrial use. The internal spring-loaded mechanism is sensitive enough to open under normal flow pressure but strong enough to snap shut instantly if back-pressure is detected. The unit is designed as a "Torch Mount" accessory, meaning it screws directly onto the oxygen inlet of your cutting torch or welding handle. It utilizes standard industry threading (typically B-size 9/16"-18 RH for oxygen), making it compatible with a wide range of Victor torch handles and compatible outfits.

Essential for Compliance and Safety

In any professional fabrication shop, safety compliance is non-negotiable. The use of check valves is widely recommended and often required by safety standards such as OSHA and NFPA in oxy-fuel setups. While check valves do not stop a flame front (flashback), they are the first line of defense against the conditions that cause flashbacks. By preventing the reverse flow of gas, they stop the creation of explosive mixtures in the hose. For complete protection, this unit should be used in conjunction with a flashback arrestor. The Victor CTO 0690-0032 is compact, measuring approximately 0.9 x 3.3 x 5.8 inches in its packaging, ensuring it adds minimal weight or bulk to the operator's tool, preserving ergonomics during precision work.

Installation and Maintenance

Installation is straightforward: simply attach the valve to the torch oxygen inlet before connecting the hose. It is crucial to ensure the flow direction arrow on the valve points toward the torch. Regular testing of check valves is recommended to ensure the internal seal remains effective against reverse pressure. Trust in Victor's legacy of safety and performance with the 0690-0032 CTO Check Valve, an indispensable asset for any gas cutting or welding rig.
