Conval: Camseal Metal-Seated Ball Valves Feature New Stem Position Indicator Disc

Camseal with new stem position indicator discConval 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. This is especially important when adding an actuator to a valve or resetting valve actuation in the field. The high-quality severe service valves are available in ½” through 4” 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) is intended to improve the accuracy of the stem and ball alignment into the valve seat. This is important in severe applications such as steam where positive, sustainable shut-off is critical and even slight mis-alignments will compromise the ball/seat sealing band. The indicator is self-securing to the stem. No set screws are required. The new disc eliminates the need for costly and multiple manufacturing features that have traditionally been used with less accuracy. This custom-engineered disc design has shown an alignment improvement of up to 3.5 times over conventional methods of position indication due to the minimization of part tolerance stack-up.

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.
