Solenoid valves serve as the critical final control elements in modern fluid process automation and gas safety networks. The industry category designated as Solenoid Valve 4 represents high-performance electromagnetic control systems featuring multi-way path routing, advanced pressure balance architectures, or robust 4-way direct-acting mechanisms optimized for low-power operations and instantaneous shut-off capabilities.
In high-risk scenarios such as petrochemical refining, urban gas transport, and municipal pipelines, the mechanical actuation speed and sealing integrity of a solenoid valve are paramount. A fraction of a second delay in valve closing can mean the difference between localized containment and catastrophic failure. As a leading manufacturer and drafting organization for national standards, we specialize in high-efficiency engineering that combines state-of-the-art electromagnetic coil design with micro-second responsiveness, ensuring complete compliance with global explosion-proof guidelines (ATEX, SIL, CE).
Our solenoid valves are equipped with proprietary electromagnetic actuators that operate safely in hazardous atmospheres. Integrating premium sealing elastomers like NBR, Viton, and FKM, these systems prevent gas fugitive emissions, meeting strict environmental and functional directives.
Empowering critical gas safety infrastructure worldwide through scalable, automated, and certified production.

Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, striving to build a safer world with sustainable gas safety technologies.
Our design approach is rooted in uncompromising compliance and technical innovation. Operating strictly under ISO9001, we deliver world-class safety certifications across international borders.
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 such as CE and SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" and "National Quality Leading Enterprise in the Gas Alarm Industry," is a member of the China Fire Protection Association, and serves as the main drafting organization for the national standard of solenoid valves, further confirming its industry influence and reputation.
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 flow monitoring functionality that integrates flow detection and alarm capabilities. The company also pioneered China's first networked bus-type gas leakage monitoring system and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security, demonstrating its leading position in cutting-edge technological research.
Our in-house laboratory is accredited by the China National Accreditation Service for Conformity Assessment (CNAS), recognized both domestically and internationally under the ILAC-MRA framework. It operates in accordance with ISO/IEC 17025, the international standard for testing and calibration laboratories. It provides reliable and traceable testing services for gas detection and alarm products, solenoid valves, and related safety equipment. Test reports issued by the CNAS-accredited laboratory are widely accepted by regulatory authorities, certification bodies, and customers in China and overseas, helping to ensure product quality, safety compliance, and market access.
Aligning advanced solenoid technology with smart monitoring systems to protect diverse industrial processes.
Industrial-scale processing demands explosion-proof enclosures and high-durability solenoid valves. By combining our CT-XF5 industrial solenoid valves with explosion-proof controllers, refineries achieve rapid, remote emergency shutdowns during critical gas leakage spikes, complying with global Safety Integrity Level (SIL 2/3) regulations.
For multi-family housing complexes and commercial kitchens, gas safety involves integrating smart household detectors (such as the JT-AT2018 or JT-AT2006 series) directly with the XF2 household gas solenoid valve. When combustible gas leaks are detected, the system immediately cuts off the gas supply and sends alerts through localized networks or IoT platforms.
Confined spaces, including municipal utility tunnels and underground gas pipelines, present extreme environmental challenges like moisture, dust, and corrosive vapors. The GT-AT0617 Series underground monitoring devices work in tandem with robust multi-way solenoid valves to automate ventilation, isolation, and system safety monitoring.
The transition from reactive safety systems to active, AI-integrated prognostic fluid controls.
Integrating pressure, temperature, and volumetric flow sensors directly into the solenoid valve manifold to provide autonomous edge monitoring and diagnostics.
Developing energy-efficient latching solenoid designs that consume power only during transitions, making them ideal for battery-operated remote systems.
Applying machine learning algorithms on cloud-based controller dashboards to predict mechanical wear, leakage, and spring fatigue before failure occurs.
Integrating wireless (LoRaWAN, NB-IoT) transmission systems into gas safety nodes to build citywide gas detection, alarm, and rapid-isolation grids.
Two decades of continuous growth, engineering milestones, and expansion into international markets.
