WESCV-31L - Western Enterprises CV-31L Fuel Gas Regulator Check Valve, B-Size LH

Reliable Reverse Flow Prevention for Fuel Gas Regulators

The Western Enterprises CV-31L is a premium-quality check valve designed specifically for Acetylene and other fuel gas regulators. Engineered to enhance safety in oxy-fuel welding and cutting operations, this valve effectively prevents the reverse flow of gases, a common precursor to dangerous gas mixing and equipment damage. Constructed from durable brass, it is built to withstand the rigors of industrial environments while maintaining a reliable seal.

This model is designed as a regulator bushing adaptor, meaning it mounts easily onto the outlet bushing of a standard regulator equipped with a B-Size outlet. The unit features a 9/16"-18 UNF Left Hand (LH) Female inlet to connect to the regulator and a corresponding Male outlet to accept standard fuel gas hoses. Its compact design, with a length of just 1.640 inches and an 11/16" hex, ensures it does not obstruct operation or add significant bulk to the setup.

Performance is a key attribute of the CV-31L. It boasts a flow capacity of 1200 SCFH at 50 PSIG, which is sufficient to match the flow capacity of most standard torches. This ensures that adding safety does not come at the cost of performance or flame stability. The valve is UL listed and manufactured in the United States, adhering to strict quality control standards. Whether for industrial fabrication, laboratory use, or general welding maintenance, this check valve is an essential component for a safe gas delivery system.
