U.S. Valve’s medical ball valve is a full-port, double seal, three piece design, with forged bronze/brass body, and chrome-plated brass ball. Only a ¼ turn of the handle is required to open/close the valve. All valves are serviceable in line, and are suitable for oxygen service per CGAG-4.1. These valves are cleaned, capped, and packaged in a polyethylene bag to prevent contamination.
