Precision-engineered hardware optimized for industrial automation, pipeline defense, and high-reliability safety loops.
In modern petrochemical, pharmaceutical, energy, and urban utility installations, safety loop integrity is a non-negotiable metric. "2 Gas Valves" (frequently categorized as 2-way gas solenoid valves, dual-stage safety shut-off valves, or smart digital pressure valves) are the primary mechanical intervention mechanisms designed to isolate hazardous media upon gas detection. Working in lockstep with combustible gas detectors and interlock control systems, these valves provide microsecond response rates to prevent catastrophic overpressurization, toxic releases, or combustion explosions.
For global enterprise buyers, procurement isn't merely a transaction of metal and actuators; it is the acquisition of systemic reliability. A failure in the main spool assembly, or an electromagnetic coil burnout, can result in complete facility shutdowns or compromise the protection of human life. As a premier manufacturer, Xinhaosi bridges the gap between mechanical integrity and industrial automation, delivering valves that stand up to corrosive atmospheres, aggressive pressure cycling, and rigorous electrical standards.
Founded in 2003, Xinhaosi is one of the most influential and trusted brands in the global gas safety industry. Over the past two decades, we have steadily built a robust and comprehensive production and service system, which integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, professional after-sales support with an experienced technician team, flexible OEM/ODM services, as well as CNAS-Accredited laboratory calibration services that meet international standards.
Our diversified product portfolio covers industrial & residential gas detection & alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to adapt to complex working environments and strict safety requirements. We produce and sell tens of millions of units annually, catering to a wide range of industries that demand reliable gas detection solutions, including oil & gas exploration and production, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, new energy, steel production, and beverage processing.
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, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
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, SIL. Additionally, Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise", "National Quality Leading Enterprise in the Gas Alarm Industry," member of the China Fire Protection Association, and 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.
Global gas safety infrastructure procurement requires balancing strict quality parameters with cost efficiency. Purchasing from premier Chinese manufacturers like Xinhaosi offers specific systemic advantages:
Based across our Chengdu and Deyang facilities, we utilize regional supply ecosystems for premium raw copper, engineering plastics, and specialized solenoid components, minimizing transport and assembly times.
High-speed CNC machinery, automated winding equipment, and digital leak-testing tables ensure each gas valve meets precise tolerances, eliminating the variances found in manual processes.
Leveraging our CNAS-accredited laboratory, we provide custom threshold calibration, bespoke threadings (NPT, BSP, Flanged), and tailored electrical connections directly from the production line.
Different working conditions place distinct structural and electronic demands on gas control loops. Our product line is designed to operate safely across a range of specialized conditions:
Explosion-proof safety enclosures (ATEX/IECEx grade) are required for valve operations in hazardous refinery zones, off-shore platforms, and chemical storage facilities where flammable vapors occur regularly.
Installed within regional regulator stations, our smart AI valves interface with remote RTUs to provide autonomous pipeline isolation in response to localized pressure drops or seismic activity.
Under-counter, low-voltage, manual-reset gas valves linked directly to household methane detectors provide simple, robust protection against localized pipe failures and appliance gas leaks.
Gas infrastructure must comply with local national and international standards. A valve that is compliant in one region may fail safety inspections in another. Xinhaosi helps partners navigate this landscape with global testing and compliance support:
Certifying that the probability of failure on demand (PFD) meets industrial risk reduction factors (e.g. SIL 2/SIL 3 loops).
Guaranteeing that electrical actuators and solenoid coils will not act as ignition sources in flammable mixtures.
Traceable international calibration in accordance with ISO/IEC 17025 standardizing test certificates globally.
Verifying that valves comply with European gas appliance regulations and electromagnetic compatibility directives.
The gas safety industry is transitioning from reactive response loops to predictive, preventative safety management. Xinhaosi is at the forefront of this shift, integrating edge computing and advanced communication protocols directly into control hardware:
Equipped with internal pressure and flow sensors, these devices monitor operational baseline fluctuations, alerting operators to spool wear, valve seat leakage, or coil degradation before a failure occurs.
Integrating LoRaWAN, NB-IoT, and 4G communication technologies, these devices enable remote valve monitoring and automated testing in pipelines located in remote or inaccessible areas.
Valves connect directly with central DCS or SCADA environments, allowing operators to run health checks on safety loops and manage shutdown actions from a centralized control room.

Detailed responses to common engineering, compliance, and integration queries from system integrators and procurement managers.
Xinhaosi emergency gas shutoff solenoid valves are designed to close within 0.3 to 1.0 seconds of receiving a trigger signal from the control unit or sensor panel, helping prevent hazardous concentration build-up in emergency scenarios.
Manual reset designs prevent the valve from automatically reopening when power is restored or a gas alarm clears. This requires technicians or safety officers to physically inspect the site, identify and resolve the leak source, and manually pull the valve lever to resume flow, ensuring safe operations.
