Industrial QZM2VB1DSS Valve Position Indicator

QZM2VB1DSS is a StoneL Quartz Valve Position Indicator, a rugged device that provides both a clear visual status of a valve and an electrical SPDT (single-pole, double-throw) output rated for 125/250 VAC. It is designed to mount to standard actuator pads (VDI/VDE 3845/Namur-compatible) and to work with common quarter-turn valve installations, offering easy installation via compatible mounting hardware. As part of StoneL’s Quartz line—now a Valmet brand—the indicator is built for demanding process environments and delivers reliable valve-position feedback that can be read from a distance, aiding start-up checks and ongoing operation. Typical applications span chemical processing, oil and gas, pharmaceutical and biotech, food and beverage, and water/wastewater treatment, where robust washdown resistance and corrosion tolerance are important considerations. The model designation QZM2VB1DSS identifies a changeover-contact arrangement suitable for signaling valve status to control systems or interlocks without requiring external power for the switch itself. With straightforward integration into existing valve assemblies and compatibility with StoneL mounting kits, the QZM2VB1DSS provides compact, dependable position indication that supports conventional valve automation practices and enhances process safety and operability.
