Explore our state-of-the-art gas detection, pressure monitoring, and auto-isolation solutions for large-diameter pipelines.
Founded in 2003, Xinhaosi is recognized as one of the most influential and trusted brands in the global gas safety and control industry. Over the past two decades, we have built a robust and comprehensive production ecosystem that integrates cutting-edge R&D, intelligent manufacturing, advanced automation equipment, digital marketing across global channels, and professional after-sales support managed by a highly specialized technical team. In addition, our flexible OEM/ODM capabilities are complemented by CNAS-Accredited laboratory calibration services that meet strict international standards.
Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves (with a particular focus on large-flow 3-inch solenoid valves), and urban gas pipeline network monitoring systems. These technologies are engineered to adapt to harsh working environments, aggressive chemical environments, and strict industrial safety standards.
“We produce and sell tens of millions of units annually, catering to critical safety-first sectors including oil & gas exploration, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, steel production, and food & beverage processing.”
Understanding how large-diameter (DN80) solenoid valves are transforming under modern industrial automation and functional safety mandates.
Adhering to strict ISO9001 quality management standards, Xinhaosi's products carry comprehensive safety certifications, including the national compulsory Product Certification (3C), explosion-proof certification (Ex d IIC T4/T6 Gb), fire product certification, CPA measurement instrument type approval, and international credentials like CE and SIL.
Notably, Xinhaosi stands as a main drafting organization for China's national standards for gas solenoid valves, demonstrating our recognized technical authority and influence across the sector. We have been awarded honors such as the "National Quality Integrity Benchmark Enterprise" and the "National Quality Leading Enterprise in the Gas Alarm Industry."
With over 50 patents and software copyrights, Xinhaosi has built an advanced innovation system. Our proprietary graphical monitoring software reduces equipment failure rates by over 30% through predictive data analytics. We also pioneered a solenoid valve featuring integrated flow detection and alarm capabilities, alongside China's first networked bus-type gas leakage monitoring system certified by safety authorities.
Our in-house calibration lab is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), operating under the ILAC-MRA framework. Recognized globally, our testing processes comply fully with ISO/IEC 17025. Reports issued by this facility are recognized by international regulatory bodies, offering clients globally consistent proof of performance and compliance.
Procurement directors and EPC engineers follow strict technical check-lists when sourcing large-bore DN80 solenoid valves. Here are the core specifications:
The global industrial valve market demands short lead times and consistent batch-to-batch quality. Xinhaosi achieves this through our integrated Factory 4.0 infrastructure across our Chengdu and Deyang production complexes. By transitioning from manual assembly lines to digital and automated manufacturing cells, we offer significant advantages to international procurement partners:
