This ball valve now has a stem-position indicator disc
This company recently introduced a new stem-position indicator disc for its Camseal metal-seated forged ball valves (photo) for easy, precise on-site identification and inspection of the open-close status of the valve. The high-quality severe-service valves are available in½- through 4-in. sizes with socket weld, butt weld and flanged ends, in pressure classes from ASME 900 through 4500. The new Stem Position Indicator Disc design (patent pending) increases the visibility and accuracy of stem and ball alignment into the valve seat. This is critical in severe applications, such as steam, where positive, sustainable shutoff is critical. — Conval, Enfield, Conn.
