OVERVIEW

Techniweld Torch Mount Check Valve Pair

The Techniweld 24-CV7PRP Check Valve Pair is a fundamental safety component for all oxy-fuel welding, cutting, and heating applications. Designed to mount directly to the torch inlets, these valves serve a critical function: preventing the reverse flow of gases. Reverse flow can occur when a tip becomes clogged or when one gas cylinder runs empty, causing the higher-pressure gas to back up into the lower-pressure hose. This condition creates a potentially explosive mixture within the hose or regulator. These check valves utilize a spring-loaded mechanism that remains open during normal flow but instantly seals shut if back-pressure is detected.

Engineered with precision, the set includes two valves: one with right-hand threads for oxygen and one with left-hand threads (notched) for fuel gas. Both feature standard "B" size 9/16"-18 fittings, ensuring compatibility with the vast majority of industrial cutting torches and welding handles from major brands like Victor, Harris, and Smith. The body is machined from high-quality brass, offering excellent resistance to corrosion and physical damage in rugged workshop environments.

It is important to note that while check valves stop reverse flow, they do not stop a flame front (flashback). For complete protection, they should be used in conjunction with flashback arrestors. However, check valves are the first line of defense and are mandatory in many safety protocols. The compact and lightweight design of the 24-CV7PRP ensures that the balance and ergonomics of the torch are not compromised, allowing operators to work comfortably while maintaining high safety standards.

FAQ

A check valve prevents the reverse flow of gas, while a flashback arrestor stops both reverse flow and the flame front of a flashback. Check valves are a first line of defense.

These specific valves (24-CV7PRP) are designed to mount directly to the inlet of the torch handle.

Yes, provided your torch uses standard "B" size fittings (9/16"-18), which is the industry standard for most medium to heavy-duty torches.

Many flashback arrestors have built-in check valves. However, having check valves at the torch provides immediate protection at the point of use. Always check your system's flow requirements.

It is recommended to test them regularly (at least annually) for reverse flow leaks and replace them every 3-5 years or if they fail a test.

Yes, the fuel check valve is compatible with all standard fuel gases including Acetylene, Propane, and Propylene.

They are designed with low cracking pressure to minimize flow restriction, but all safety devices add some slight resistance. They are suitable for standard cutting and welding applications.

The fuel gas valve has a notched nut and left-hand threads, while the oxygen valve has a smooth nut and right-hand threads.
