CV30R - Western CV-30R Oxygen Regulator Check Valve, B-Size 9/16"-18 RH

Technical Overview of the Western CV-30R Oxygen Check Valve

The Western CV-30R is a precision-engineered reverse flow check valve designed specifically for oxygen service in industrial welding and cutting applications. Manufactured by Western Enterprises, this component serves as a critical safety barrier, preventing the accidental backflow of gases into the regulator and cylinder. The unit is constructed with a durable brass body and features internal components made from stainless steel, including the operating spring and valve disc, ensuring corrosion resistance and reliable actuation over a long service life.

Designed for seamless integration into existing gas distribution systems, the CV-30R features a B-Size 9/16"-18 UNF Right-Hand (RH) thread configuration. It is engineered to mount directly onto the outlet bushing of any standard oxygen regulator. The valve is rated for a maximum pressure of 125 PSIG and demonstrates a substantial flow capacity of 1200 SCFH at 50 PSIG, making it suitable for heavy-duty cutting operations involving up to 12 inches of steel. The valve mechanism is calibrated for high sensitivity, requiring only 3 ounces of pressure to open, thereby minimizing flow restriction during normal operation. Conversely, it requires only 10 ounces of reverse pressure to positively close, creating an immediate seal against backflow.

Compliance and safety are paramount in the design of the CV-30R. The product is UL Listed and meets or exceeds the rigorous standards set by the Compressed Gas Association (CGA) and OSHA. By preventing the mixing of gases in the regulator, this check valve mitigates the risk of contamination and potential chemical reactions within the high-pressure equipment. It is an essential component for any compliant oxy-fuel setup, providing a reliable mechanical safeguard without impeding the performance of the torch or regulator.
