Technical Strength and Laboratory R&D Instruments

Technical Strength & Calibration Laboratory

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.

Macro Industrial Safety Solutions & Safety Shut Off Architecture

Modern hazardous industries operate under tight tolerance margins. Our macro solutions leverage physical isolation and rapid data integration to protect assets and human lives.

Petrochemical & Refineries

Volatile hydrocarbons demand fast-response automated safety shut off systems. Our explosion-proof gas detectors (such as the GTYQ-AT0602A and GTYQ-XP4000B) form a real-time safety loop with heavy-duty solenoid valves. Should the gas concentration surpass 20% LEL, the interlock control box triggers an instantaneous electrical pulse, isolating the gas line within 0.5 seconds.

Municipal Gas Distribution

Underground municipal grids require pressure stability and remote emergency capability. Xinhaosi’s IoT-enabled pressure monitors (GT-AT0637) continuously track pipeline pressure fluctuations, feeding telemetry data back to centralized SCADA systems. In critical pipe rupture scenarios, the dry battery-powered wireless solenoid valves shut off lines automatically to prevent city-wide hazards.

Industrial Burner & Boiler Safety

Industrial furnaces utilize our double-block-and-bleed safety shut off systems to prevent unburnt gas from accumulating in combustion chambers. Combining our high-sensitivity IFD2020 flame detector with the XF3 Series industrial solenoid valves ensures that if a flameout occurs, the gas supply is cut instantly, eliminating explosion risks in boiler rooms.

Did you know? Over 70% of combustible gas explosions in commercial spaces are due to slow manual isolation. Modernizing to automated solenoid shut-off systems with sub-second response times reduces safety incident severity rates by more than 85%.

Localized Safety Scenarios & Compliance Standards

Safety protocols depend heavily on location-specific legislation. As an OEM manufacturer, we design and calibrate our products to fulfill global regulatory mandates.

Enforcing Safety Codes Globally

To access markets like Europe, North America, and Southeast Asia, manufacturers must prove compliance with local safety standards. Our production processes conform to European standard EN 161 (for automatic shut-off valves) and safety integrity levels SIL 2/3 according to IEC 61508. This ensures that the probability of failure on demand (PFD) remains within strict regulatory limits.

Xinhaosi's in-house laboratory calibration is traceable under the ILAC-MRA (International Laboratory Accreditation Cooperation) framework, meaning test reports issued by our facility are recognized by international accreditation bodies. This significantly accelerates local product certifications, helping our OEM partners fast-track their supply chains.

Technical FAQ: Safety Shut Off Valves & Controls

Detailed guidance from our engineering and compliance teams on gas safety and hardware options.

1. What is the fundamental difference between manual-reset and automatic-reset safety shut off valves?

Manual-reset safety shut-off valves require a human operator to physically open the valve once it has been tripped. This is a critical safety standard for industrial gas lines, ensuring that line pressure and safety checks are verified before restarting gas flow. Automatic-reset systems can open without on-site personnel and are generally limited to specific low-risk utilities or remote systems where monitoring occurs via SCADA control loops.

2. How does a CNAS-accredited laboratory test safety valves for global compliance?

Our CNAS-accredited laboratory, operating under ISO/IEC 17025 standards, conducts rigorous tests for leakage rates, seat tightness, electrical coil insulation strength, cycle durability, and rapid closing times. Because our laboratory is recognized under the ILAC-MRA framework, our test data is globally accepted, simplifying compliance certifications such as CE, ATEX, and local gas authority approvals.

3. What is the target LEL threshold for safety shut-off trigger systems?

In most industrial and commercial boiler rooms, safety controllers (such as the JB-TB-AT2020SE) trigger alarm procedures at 10% or 15% LEL (Lower Explosive Limit). A complete emergency safety shut off via solenoid valves is typically initiated when the gas concentration reaches 20% to 25% LEL to prevent gas-air mixtures from reaching flammable thresholds.

4. Can wireless smart pressure monitors operate continuously in hazardous zone classifications?

Yes. Our GT-AT0637 Wireless Smart Pressure Monitor is designed with intrinsically safe circuitry and explosion-proof enclosures. It carries international Ex certificates and can be deployed directly in Zone 1 and Zone 2 hazardous areas, transmitting real-time pipeline pressure metrics via secure, low-power industrial networks.

5. How does a flow-monitoring safety valve reduce system operational failure rates?

Our patented flow-monitoring solenoid safety valves feature integrated sensors that compare actual gas flow rates against baseline expectations. If a sudden drop in pressure or a massive spike in flow is detected (such as from a pipe rupture downstream), the valve automatically trips. This feature helps decrease systemic failure rates by more than 30% through early identification of piping issues.

6. What maintenance routine is recommended for industrial solenoid valves?

Industrial solenoid valves should undergo periodic proof testing every 6 to 12 months. This includes checking for seat wear, coil resistance degradation, and confirming the valve trips within its specified response window (less than 1 second). Sensors within the interlinked gas detection unit should be calibrated using reference gases at similar intervals to maintain compliance with safety codes.
