StoneL Quartz SST Universal Valve Monitor QN35C02NRA QN35C03NRA QN35D05NRA QN35D06NRA QN35A05HDM

StoneL QN35C02NRA is a Quartz QN35 SST Universal Valve Monitor designed for automated valve position indication and industrial control system feedback. This variable product also includes QN35C03NRA, QN35D05NRA, QN35D06NRA and QN35A05HDM, allowing buyers to request the appropriate ordering configuration for their valve automation projects.

StoneL QN35C02NRA Quartz SST Universal Valve Monitor

The StoneL Quartz QN35 series is part of the manufacturer’s industrial on/off valve monitoring portfolio. Its SST Universal normally open dual-sensor technology supports valve position feedback, while the Quartz platform combines electrical monitoring with visual valve position indication.

In automated process facilities, accurate valve feedback helps operators supervise equipment conditions and coordinate plant operations. Furthermore, the correct position monitoring configuration can support maintenance planning and control system integration. As a result, selecting the appropriate StoneL QN35 ordering code is an important part of reliable industrial automation.

The Quartz QN platform includes nonincendive configurations and certain intrinsically safe options. However, the suitability of a particular product for a hazardous installation depends on its exact approval, electrical configuration and installation requirements. Therefore, customers should always verify the complete manufacturer documentation.

Available StoneL Quartz QN35 Models

Wuhan Yuli Automation provides sourcing and quotation assistance for five StoneL Quartz QN35 references. Although these models belong to the same product family, their complete ordering codes identify different configurations. Consequently, customers should select the exact model required by their existing equipment.

Ordering Notice: The standard manufacturer model selector identifies the QN35 sensor family and several enclosure, entry and indicator options. However, the complete QN35A05HDM configuration requires additional manufacturer verification. Do not assume that the five models are interchangeable.

Key Features and Benefits

StoneL QN35C02NRA SST Universal Sensor Technology

The QN35 function code identifies a dual SST Universal normally open switching sensor module in the manufacturer’s Quartz ordering system. This technology is intended for industrial valve position monitoring. In addition, suitable configurations can provide discrete valve status information for integration with automated process control equipment.

Clear Valve Position Indication

The Quartz platform offers visual indicator configurations that help plant personnel identify valve status locally. For example, the RA indicator arrangement represents red for closed and green for open. Consequently, operators can obtain a convenient visual reference during equipment inspection and routine maintenance.

Industrial Enclosure and Connection Options

Different Quartz ordering codes identify electrical entry and enclosure arrangements. The manufacturer lists NPT and metric conduit entry options for the QN family. Therefore, selecting the correct connection configuration is important when replacing an existing unit or designing a new valve assembly.

Convenient Maintenance and Model Replacement

Correct part number identification helps reduce purchasing mistakes and unnecessary equipment modifications. Furthermore, the Quartz family includes features intended to simplify access and adjustment. However, replacement compatibility must be confirmed using the complete ordering code, rather than relying only on external appearance.

Industrial Applications

StoneL Quartz QN35 valve position monitors may be considered for automated on/off valve systems in several process industries. Actual application suitability depends on the selected configuration and site requirements.

• Oil and Gas: Position monitoring for automated valves in processing facilities.
• Petrochemical: Valve feedback integration with process control equipment.
• Chemical Processing: Status indication for industrial valve automation systems.
• Power Generation: Monitoring of auxiliary and process valves.
• Water Treatment: Automated valve position supervision in treatment facilities.
• Pulp and Paper: Valve feedback for production and utility operations.
• Marine and Offshore: Position monitoring where the selected enclosure and approvals meet installation requirements.

For projects involving classified hazardous areas, customers must verify the applicable product approval, electrical interface and installation instructions. The QN family designation alone does not establish approval for every operating environment.

How to Select the Correct StoneL QN35 Model

First, identify the full model number printed on the existing valve monitor. Next, review the required sensor function, enclosure configuration and conduit entries. Then, compare the visual indication arrangement and mechanical connection requirements with the existing installation.

For example, QN35C02NRA and QN35C03NRA have different conduit entry configurations. Similarly, QN35D05NRA and QN35D06NRA identify different metric entry arrangements. These differences should be checked before purchasing a replacement product.

Additionally, QN35A05HDM should be reviewed against its original equipment documentation because its complete configuration has not been independently verified. Customers can provide a clear nameplate photograph and any available manufacturer drawings to assist with identification.

Finally, include the required quantity, delivery country and purchasing schedule when requesting a quotation. Providing complete information helps the sales team prepare an appropriate commercial offer.
