Over the past two decades, we have built a robust and comprehensive manufacturing ecosystem, integrating advanced research and development, smart manufacturing, global sales channels, and dedicated engineering services.
Our diversified product portfolio covers industrial and residential gas detection and alarm systems, industrial and household gas solenoid valves, and smart urban gas pipeline network monitoring systems. All of our engineering efforts focus on building fail-safe mechanisms capable of operating in highly demanding industrial environments.
Chengdu HQ, R&D Hub & Intelligent Production Facility
Xinhaosi's manufacturing strategy relies heavily on automated manufacturing assets to achieve repeatable product compliance. With our two key production campuses located in Chengdu and Deyang, we boast cleanrooms, automated assembly lines, high-speed SMT processes, and automated functional testers.
Our Deyang manufacturing base represents a major leap in modern factories, deploying a custom ERP system linked to PLC-driven calibration devices. This integration enables full components traceability for safety valves and detection units. Our production efficiency allows us to cater to massive volume requests from global municipal utility companies and tier-1 industrial gas brands under custom OEM/ODM parameters.
Deyang Smart Factory - Advanced Production and Logistics Hub
Quantifiable achievements validating our market presence and technological capability.
Adhering to strict international safety standards to provide field-proven dependability.
Operating in high-hazard environments requires high conformity to international standards. Xinhaosi manufactures its entire product catalog in compliance with ISO9001 quality management procedures. Our products have obtained a comprehensive matrix of safety certifications, including China's National Compulsory Product Certification (3C), explosion-proof certifications, CE approvals, and **SIL (Safety Integrity Level) 2 & 3 ratings**.
Additionally, Xinhaosi operates an in-house laboratory accredited by the CNAS (China National Accreditation Service for Conformity Assessment), conforming to the **ISO/IEC 17025** standard. This lab is recognized globally under the **ILAC-MRA** framework, ensuring that all calibration, performance verification, and environmental stress screening tests conducted on our solenoid valves are traceable and legally recognized worldwide.
Our technological innovations include a state-of-the-art graphical monitoring framework for gas networks that lowers equipment failure rates by over 30% via historical predictive metrics. We also hold proprietary designs for flow-monitoring safety valves that merge gas detection and mechanical shutoff functions into one compact device.
In-house CNAS-accredited Environmental and Calibration Laboratory
How Xinhaosi leverages localization, industrial clustering, and automated production to provide unbeatable global advantages.
Our Chengdu and Deyang factories reside inside prime industrial manufacturing clusters. This proximity yields direct access to raw material processing centers for refined brass, engineering plastics, electromagnetic coils, and high-tolerance seals, shrinking delivery times and production overheads.
Western factories typically feature rigid production lines optimized for static catalogs. Xinhaosi maintains flexible, modular manufacturing pipelines that easily adapt to specific requirements for coil voltages, connector threads (NPT/G), body materials (brass/aluminum), and custom laser-engraved branding.
By investing heavily in automated CNC machining centers, automated testing bays, and computer-driven diagnostic equipment, we maintain low labor costs while achieving top-tier tolerances. These cost savings are passed directly to our commercial partners.
How Xinhaosi safety systems secure operations across critical municipal and industrial infrastructures.
Natural gas safety in urban environments demands instant automatic shutoff valves connected directly to household and main pipeline network monitors. When pressure spikes or methane concentrations cross preset thresholds, the system shuts down gas supplies in milliseconds to prevent explosions.
Refineries and chemical plants handle toxic, flammable gases constantly. Our heavy-duty explosion-proof gas detectors (such as the GTYQ series) pair with industrial solenoid valves to establish a robust safety loop. They withstand severe operating temperatures and harsh saline or corrosive chemical atmospheres.
Enclosed spaces like underground garages require automated ventilation systems managed by carbon monoxide (CO) gas detectors. Integrating AT2004BIV-CO detectors with automated HVAC systems prevents toxic gas buildup, protecting visitors while optimizing energy usage.
The transition toward connected, automated, and green flow control systems.
Modern flow control systems are transforming from passive components into smart, connected devices. The integration of IoT modules, wireless sensors, and edge-intelligence enables solenoid valves to transmit diagnostic reports, seal wear metrics, and pressure readings to supervisory control centers in real-time.
Xinhaosi leads this transition by introducing wireless pressure monitors and cloud-connected gas detection controllers. These solutions enable predictive maintenance schedules that eliminate sudden shutdowns, securing industrial uptime and safeguarding operational staff.
As industries target decarbonization, gas networks are preparing to transport hydrogen blends. Hydrogen's light molecular structure demands superior sealing designs and low-friction materials. Xinhaosi is actively researching new polymer seal formulations and optimized gas paths to handle hydrogen and green gas mixtures safely.
Global procurement managers face intense pressure to balance equipment costs with strict safety compliance. When sourcing solenoid valves and detection units, buyers look for manufacturers that provide comprehensive documentation, certified engineering records, and reliable technical support.
Our engineering services bridge these gaps. We supply detailed diagnostic reports, material traceability certificates, and direct support from our experienced technical team. This comprehensive approach simplifies integration and ensures smooth regulatory approvals for global projects.
Over two decades of dedication to industrial gas safety innovation.
Technical guidance and answers for purchasing agents and systems engineers.
Normally Open (NO) solenoid valves remain open when unpowered. This design is ideal for safety shutoff lines, allowing unimpeded gas flow during normal operations. When a sensor detects gas leaks, the system energizes the valve's coil to shut off flow instantly. Conversely, Normally Closed (NC) valves stay closed until powered. They are typically used in fuel delivery networks to guarantee shutoff in the event of power losses.
CNAS accreditation validates that a laboratory conforms to the strict ISO/IEC 17025 standard. This verification ensures that calibration and performance data collected within our facilities are internationally recognized. This simplifies testing processes and helps global customers secure compliance with local regulatory requirements.
Forged brass is the standard choice for general-purpose applications due to its excellent strength and corrosion resistance. Lightweight anodized aluminum is popular in municipal gas distribution networks to minimize system weight. For corrosive industrial environments, stainless steel is preferred to ensure chemical compatibility and long-term durability.
Xinhaosi's explosion-proof products feature hermetically sealed coil housings that prevent electrical arcs or internal combustion from igniting ambient gas mixtures. Our explosion-proof detectors and solenoid valves carry certified 3C and international explosion-proof ratings, making them suitable for hazardous Zone 1 and Zone 2 installations.
Standard modifications, such as customized threads (NPT, BSP, G), special voltages (12VDC, 24VDC, 110VAC, 220VAC), or alternative seal materials (NBR, FKM), are usually completed in 4 to 6 weeks. Full ODM projects that require clean-sheet design engineering, custom tooling, and certification support are scheduled through our engineering office.
We combine high-precision CNC machining with high-quality elastomer seals. Every valve undergoes bubble-tight leakage testing. This process ensures zero leakage at both low and high pressure ranges before the unit leaves the factory floor.
