StoneL QZp2SC2R Valve Point Valve Position Sensor

StoneL PQ2SC2R Quartz PQ ValvePoint Valve Position Sensor provides direct valve-position feedback to automation and safety systems by signaling the actual valve status through a discrete output. This SPDT valve-position sensor is part of the Quartz PQ family, and it delivers a signaling output of 0.3 amps at 120 VAC. It is built for demanding environments with a temperature range from -40°C to 80°C and a rugged enclosure rated to NEMA 4, 4X, and 6. The unit weighs about 5 lb and is designed to be installed on valve assemblies that require reliable position feedback for control logic or interlocks. The Quartz PQ ValvePoint family supports multiple signal outputs depending on model, including mechanical switches, proximity sensors, or a position transmitter, allowing integration with a wide range of control architectures. For proper installation and safety considerations, refer to the Stonel/StoneL Quartz product manuals, which document the valve position indicator concept and how it interfaces with valve actuators and safety systems.
