Import Cr-6033 Boiler Level Gauge — Buy in Bulk from Supplier in China

The Cr-6033 Boiler Level Gauge is a mechanical sight glass system designed for direct visual monitoring of water levels in steam boilers. It features a borosilicate glass tube enclosed in a cast iron housing with brass fittings, rated for pressures up to 1.6 MPa and temperatures up to 180°C. The gauge includes dual ball valves for isolation during maintenance and a drain valve for flushing debris.

The glass tube is 12mm in diameter with a wall thickness of 2.5mm, typical for industrial-grade sight gauges. The housing is sand-cast ductile iron with a protective enamel coating to resist corrosion. Unlike electronic models, this gauge requires no power and provides continuous visual feedback without signal delay. It complies with ASME B31.1 pressure piping standards for installation in boiler systems.

This model is commonly selected by small to mid-sized manufacturing plants, textile mills, and district heating systems where simplicity and reliability outweigh the need for digital integration. Buyers typically order in quantities of 10 to 100 units for multiple boiler lines. Trade terms include FOB Qingdao, standard packaging in wooden crates with shock padding, and lead times of 10 to 15 working days. No certifications are listed; buyers must request proof of material compliance and pressure testing.

Henan Changrun Automation System Co., Ltd is based in Zhengzhou, China, with a registered address in the Economic and Technological Development Zone. The company specializes in industrial automation instrumentation, with product lines focused on level, pressure, and temperature monitoring devices. This listing shows a harbor trust tier and no verified response rate or average response time, indicating limited buyer interaction history on the platform.

The supplier does not disclose factory size, workforce count, or export volume. No certifications, client names, or years in operation are listed. The product description confirms design and assembly capabilities but provides no evidence of in-house R&D or testing laboratories. Buyers should treat this as a manufacturer of standard instrumentation without verified quality systems unless documentation is provided directly.
