Explore our highly integrated field instrumentation, control terminals, and detection hardware manufactured to precise engineering tolerances.
The industrial landscape is undergoing a critical transition. Modern gas infrastructure no longer relies on passive mechanical shut-off systems. Today, the global energy sector dictates the implementation of active, intelligent, and highly responsive emergency shut-off valves (ESVs) capable of seamless integration into complex Supervisory Control and Data Acquisition (SCADA) frameworks and distributed control architectures.
Several macro factors are accelerating this technology roadmap:

Deyang Factory
Industrial procurement teams, engineering consulting firms, and EPC contractors prioritize specialized mechanical criteria and international compliance pathways during vendor vetting.
Procurement teams demand safety-critical valves certified under IEC 61508. High-integrity safety systems require systematic failure rate evaluations (PFDavg) to ensure reliable operation upon demand in emergency shutdown scenarios.
Valves operating in Zone 1 and Zone 2 hazardous areas must carry rigorous certifications, including ATEX, IECEx, or national compulsory approvals. Standard enclosures must incorporate flameproof (Ex d) or encapsulated (Ex mb) protections.
Industrial applications present unique physical constraints, including corrosive process media, wide temperature ranges (-40°C to +80°C), and high pressures. Standard off-the-shelf valves fail to meet these demanding parameters.

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.
Over two decades of engineering excellence, scaling from a specialized local startup to an integrated global security solutions provider.
We are shaping the future of industrial safety by embedding intelligence, machine learning, and absolute fail-safe operation directly into field hardware.
Integrating local MCU processing and algorithm-driven vibration sensors allows tomorrow's shut-off valves to independently recognize localized structural failures, seismic events, or abnormal upstream pressure changes without requiring central controller commands.
We are deploying wireless monitoring terminals capable of decade-long operations on internal lithium batteries. This eliminates expensive field wiring costs and simplifies infrastructure retrofits in remote oil depots, offshore platforms, and cross-country gas pipelines.
By merging thermal-dispersion flow detection mechanisms directly inside our gas solenoid valves, we provide dual-function instruments that concurrently act as gas flow meters and emergency valves, dramatically lowering capital expenditure for system design.
Tailoring complex gas safety architectures to meet the physical and chemical constraints of highly hazardous process operations.
Operating under corrosive hydrogen sulfide and hydrocarbon gas streams, these facilities require heavy-duty cast steel and stainless steel valve bodies. Our solutions integrate explosion-proof (Ex d IIC T6) solenoids and fire-safe certifications to meet the stringent criteria of refining complexes.
Urban systems require millions of valve operations annually across sprawling networks. Xinhaosi delivers high-flow, low-pressure drop gas safety solenoid valves designed for natural gas, LPG, and manufactured gas, featuring rapid, fail-safe manual resets.
Steel plants struggle with toxic, dirty carbon monoxide and blast furnace gases. We engineer custom valves equipped with clean-out ports, reinforced mechanical seals, and specialized debris-tolerant structures to ensure reliable sealing in harsh, dusty environments.
Detailed responses to critical engineering questions commonly encountered during global pipeline and instrumentation system design.
High-performance detection, control, and shut-off hardware designed to minimize risks in critical hazard environments.
