Premium OEM and custom engineering options for combustible, toxic detectors, and automation peripherals.
Expert insights on regulatory frameworks, functional safety (SIL), and critical infrastructure integrations.
As the global market pivots toward clean fuels, solenoid shut-off valve technology has evolved. Standard sealing media is rapidly being replaced with advanced elastomers (such as specific grades of Viton and Low-Temp NBR) designed to prevent hydrogen embrittlement. Modern OEM factories must provide gas-tight tolerances up to 10⁻⁶ mbar·l/s for hydrogen service, satisfying both domestic and international clean energy initiatives.
Today's smart industrial ecosystems require safety shut-off systems that do more than just act on binary signals. High-reliability OEM solenoid valves now integrate feedback sensors to monitor coil temperature, seat positioning, and downstream pressure decay. This facilitates preventative maintenance cycles, reducing costly unplanned facility shutdowns by predicting electrical coil failures before they occur.
For chemical complexes and municipal gas networks, safety is measured in SIL (Safety Integrity Level) ratings. Advanced solenoid shut-off valves utilize spring-return fail-safe operations that ensure complete closure in less than one second if electrical power is lost. Sourcing from a factory certified to meet IEC 61508 / SIL 2 and SIL 3 standards has transitioned from an industry preference to a mandatory regulatory requirement.

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.
Decades of performance, massive manufacturing capabilities, and globally recognized quality management.
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.
Addressing the procurement challenges and engineering requirements of international industrial operators.
Sourcing solenoid shut-off systems requires rigorous quality controls. B2B buyers mandate full material traceability (EN 10204 Type 3.1 certification) for all pressure-bearing metallic housings. Our factory guarantees 100% trace verification, validating cast body compositions to prevent stress corrosion cracking (SCC) under corrosive industrial environments.
With massive project management demands, production bottlenecks are not an option. Xinhaosi leverages state-of-the-art automation lines at our Deyang and Chengdu factories to ensure high-capacity production with short lead times. We support global logistics integration, supplying critical valves on time, every time.
No two facilities are identical. We provide bespoke solenoid design options, including various supply voltages (12VDC, 24VDC, 110VAC, 220VAC), hazardous area explosion-proof coil encapsulations (Ex d, Ex mb, Ex ia), manual-reset levers, and custom pipe connection configurations (flanged, NPT, BSPP, compression fittings).
A twenty-year trajectory of technological innovation, capacity scaling, and international growth.
Assuring regional deployment safety while mapping the next generation of smart valves.
Xinhaosi guarantees full local compliance across target jurisdictions. From EU CE-PED (Pressure Equipment Directive) and ATEX explosion-proof requirements to international SIL 2 functional safety standards and CNAS accreditation. All test standards run in strict coordination with ISO/IEC 17025 protocols, easing local market entry hurdles.
Our upcoming 2025-2030 product generation centers around AI safety valves. By embedding micro-sensors directly within the solenoid housing, the valve continuously processes localized metrics (such as vibration, delta pressure, and cycle count), communicating directly with plant SCADA systems to forecast maintenance schedules before an issue occurs.
For large-scale processing facilities, wired safety networks present extreme installation and maintenance costs. Our wireless detection systems integrate LoRaWAN and NB-IoT protocols to trigger remote solenoid valves without control cabling, maintaining high industrial safety standards.
