OVERVIEW

Critical Safety for Oxy-Fuel Systems

The ESAB Check Valve (Regulator to Hose) is an essential safety component designed to prevent the reverse flow of gases in oxy-fuel welding and cutting setups. Reverse flow can occur when one gas feeds back into the other gas line due to a clogged tip, empty cylinder, or improper pressure settings. This condition can lead to the mixing of oxygen and fuel gases within the hose or regulator, creating a highly dangerous situation. This check valve mechanically closes the line instantly when back-pressure is detected, stopping the reverse flow before it reaches the regulator.

Robust Construction and Reliability

Manufactured from high-quality brass, this check valve is built to withstand the rigorous demands of industrial environments. The corrosion-resistant body ensures a long service life and maintains seal integrity over time. Its internal spring-loaded mechanism is calibrated to allow unrestricted forward flow during normal operation while reacting immediately to any back-pressure. This ensures that your gas supply remains stable and efficient without compromising safety.

Installation and Compatibility

Designed specifically for mounting between the regulator outlet and the hose, this valve is easy to install on standard oxy-fuel equipment. Its compact form factor ensures it does not interfere with the operation of the regulator or add excessive bulk to the setup. Regular inspection and testing of check valves are recommended to ensure they remain free of debris and function correctly, maintaining the highest safety standards in your workshop.

FAQ

The primary function is to prevent the reverse flow of gas from the hose back into the regulator, which prevents dangerous gas mixing.

This specific model is designed to be installed at the regulator outlet, connecting the regulator to the hose.

No, a check valve only stops reverse gas flow. A flashback arrestor stops both reverse flow and a flame front. For maximum safety, both are often recommended or required.

Check valves are typically threaded specifically for either oxygen (right-hand thread) or fuel gas (left-hand thread). Please verify the specific thread direction of the SKU before installation.

Check valves should be tested for reverse flow leaks at least once every six months or according to manufacturer guidelines and local safety regulations.

The valve body is constructed from durable brass to resist corrosion and withstand high pressures.

Most standard check valves are designed for typical welding and cutting flow rates. For extremely high-flow heating applications, verify the flow capacity rating to ensure it does not restrict performance.

ESAB products typically carry a manufacturer's warranty against defects. Please check the specific warranty terms for accessories and safety devices.
