Explore our elite selection of industrial detectors, safety control panels, and specialized interface modules manufactured under strict global standards.
For critical infrastructure, the 1" Normally Closed (N.C.) Solenoid Valve serves as the primary failsafe. It remains closed under loss of power to prevent gas propagation or chemical contamination, maintaining systemic safety in hazardous areas.
Utilizing high-end engineering polymer diaphragms and specialized magnetic coils, our valves achieve high-speed closure within <50 milliseconds, minimizing downstream pressure surges and protecting delicate instruments.
Every batch of our 1" valves is calibrated in our in-house CNAS-Accredited Laboratory, validating compatibility with international SIL levels, CE requirements, and rigorous explosion-proof certifications (Ex d IIC T6).

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.
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, ensuring product quality, safety compliance, and market access.
Unpacking the engineering requirements, global supply dynamics, and macroscopic solutions for high-performance gas containment.
Industrial procurement departments faces mounting hurdles. High pressure, corrosive environments, and hazardous operational settings call for extremely robust solenoid valves. 1" Normally Closed (N.C.) solenoid valves operate as a critical block in process lines, where a power failure forces the valve shut, halting the flow of potentially volatile media. Global buyers must evaluate:
Different industry verticals have distinct performance metrics for solenoid valves. Xinhaosi approaches these through specialized engineering frameworks:
High flow capacity (Cv) and minimal pressure drop are required for distribution networks. Xinhaosi’s 1" valves reduce inline turbulence, ensuring stable delivery to household systems while maintaining the capability to seal off distribution zones during pressure spikes.
Petrochemical lines often process aggressive compounds. The selection of FKM, EPDM, or Kalrez seals prevents elastomer deterioration, mitigating risk in volatile chemical environments.
Our solenoid valves interface with SCADA systems. When gas detectors identify a hazardous leak, they command the 1" N.C. valve to isolate the gas supply, mitigating risk and protecting facilities.
The solenoid valve sector is transitioning from mechanical units to digital modules. By incorporating flow instrumentation, pressure sensors, and smart communication protocols, today's safety systems are more integrated than ever. Xinhaosi is at the forefront of this evolution:
