Conval: Camseal Metal-Seated Ball Valves Feature New Stem Position Indicator Disc
Conval recently announced that its popular Camseal© metal-seated, forged ball valves feature a new Stem Position Indicator Disc for easy, precise on-site identification and inspection of the open-close status of the valve.
Patented, top-entry in-line renewable Camseal ball valves provide significant savings in labor, materials and downtime. In-line renewability is typically accomplished within 30-minutes in the event of process application abuse. The cartridge is conveniently removed for on-site parts replacement, reassembly and re-installation. No welding is required, which is especially important with F91 valves.
Camseal ball valves feature zero body, seat and stem leakage on stand-alone and actuated valves. Each valve is manufactured in the U.S.A. to rigorous global QA qualifications including ASME, ISO 9001, CE and Canadian Registration numbers for all provinces. As a result, Camseal ball valves offer exceptionally reliable and long life far beyond industry standards. Fire-safe, N and NPT stamp, TPD-1-2013 compliant, and full port valves are also available. Standard materials include carbon steel SA-105, stainless steel SA-182-F316/F316L, Alloy SA-182.F22 CI.3, SA-182-F91. Other materials are available upon request.

Q: I’ve heard that cobalt-base Alloy 6 materials should not be used in boiler feedwater service.
Q: I need to qualify a welding procedure specification per the ASME Boiler and Pressure Vessel Code.
For decades, valve manufacturers have provided the maximum recommended working pressures and temperatures for their products, based on the materials used in the pressure-containing parts.
