Guided by the core mission of “Making Gas Safety Accessible Everywhere,” we consistently deliver high-performance, reliable products and customized solutions tailored to each client’s unique needs. Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team.
Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Products Certification, explosion-proof certification, fire product certification, CPA measurement instrument type approval certificate, and international approvals as CE and SIL (Safety Integrity Level). Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" and "National Quality Leading Enterprise in the Gas Alarm Industry," and serves as a standing member of the China Fire Protection Association and the main drafting organization for the national standard of solenoid valves, confirming our leading industry footprint.
In the field of intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. These patents cover core technological areas, including a graphical monitoring system for gas detection and alarm, which enables predictive maintenance based on historical data to reduce equipment failure rates by over 30%, and a solenoid valve with integrated flow monitoring functionality.
Our in-house calibration laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. Operating strictly in accordance with ISO/IEC 17025, it provides traceable testing for gas detection and safety valve products. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities and global customers, paving the way for seamless international trade and deployment.
From purely mechanical containment to IoT-enabled safety systems, explore how industrial stop valves are transitioning to meet the needs of tomorrow's smart infrastructure.
Traditional solenoid stop valves are blind units that act only when powered or tripped. Our current R&D is centering on integrating pressure, temperature, and cycle-count sensors directly into the valve housing. This enables Modbus, CAN-bus, or wireless LoRaWAN communication, sending real-time health data to SCADA systems before failure occurs.
By employing dual-coil structures and permanent magnet latching mechanisms, our next-generation stop valves require energy only during the millisecond-long switching phase. This drastically reduces operating temperatures, eliminates thermal drift in continuous duty cycles, and allows for battery-powered operational longevity.
Utilizing high-performance fluoroelastomers and metal-to-metal dynamic seals, the next-gen valves monitor seal-face deterioration by measuring slight micro-leakages using integrated gas-sensing chambers built into the bonnet. This yields zero-leakage security, aligning with Net-Zero fugitive emission targets.
Our stop valves and detection systems are engineered to act as unified, fail-safe barriers across complex industrial applications.
In highly volatile refinery operations, ambient combustible gases present a constant hazard. Our Ex-d explosion-proof detectors (e.g., GTYQ-AT0602 and XP3000 series) continuously scan the environment. If gas levels breach safety margins, they interface via interlock control boxes directly with heavy-duty solenoid stop valves (normally open/closed options), isolating the gas feed lines in under 1 second. This level of rapid automation mitigates catastrophic fire and explosion risks in hydrocarbon processing facilities.
Distribution networks span hundreds of miles of pipelines where monitoring and swift containment are vital. Xinhaosi provides full-scale urban gas monitoring solutions, combining pressure transmitter controllers (PMC-X602C) with macro-sized solenoid stop valves. If a major pipe fractures or experiences pressure drops, automated emergency valves snap shut instantly, preventing gas accumulation in public spaces and avoiding large-scale municipal disruptions.
The rise of green hydrogen and battery manufacturing demands quick gas containment. Hydrogen's extremely light molecular weight makes it highly prone to leakage, requiring highly specialized seal materials. Xinhaosi’s engineering team designs high-integrity stainless steel stop valves that feature specialized sealing systems to prevent micro-leaks, ensuring process safety in industrial energy storage fields.
For high-rise residential properties and commercial kitchens, household safety is paramount. Our dry battery type wireless solenoid valves (designed for household use) combined with JT-AT2007 gas detectors offer cost-effective, easy-to-install options. The system operates on low-voltage pulses, shutting down household pipelines at the source of a leak, and warning residents locally and via IoT interfaces.
Operating out of our two central manufacturing sites—Chengdu and the newly operational Deyang Intelligent Factory—Xinhaosi integrates advanced automation, robotic component machining, and precision electronic board assembly. Our Factory 4.0 infrastructure guarantees high output capacity alongside strict quality control, insulating global supply chains against supply crunches.
For multinational enterprise procurement managers, choosing Xinhaosi as your OEM stop valves partner provides access to key structural advantages:
We accommodate customized valve body markings, custom thread options (BSPP, BSPT, NPT), alternative operating voltage profiles (DC12V, DC24V, AC220V), and client-branded enclosures for gas detector lines. Our engineering division works directly with your engineering leads to resolve design issues from prototype development to mass manufacturing.
Navigating complex international safety standards requires engineering and document support. Here's how we facilitate compliance.
We provide full verification documentation, including certificate of origin, chemical testing reports, pressure test verification records, and detailed export documentation, ensuring smooth customs processing and hassle-free clearance at the port of entry.
Our industrial shut-off stop valves and gas detection controllers conform to safety instrumentation systems (SIS) standards. Obtaining SIL certificates allows engineers to confidently utilize our hardware in safety-critical automated shutdown loops.
