In complex industrial manufacturing, petrochemical refining, and urban utility distribution, gas control valves serve as critical infrastructure nodes. A gas solenoid valve or automated shutoff safety valve regulates system pressures, monitors upstream leakage risks, and ensures dynamic containment under explosive limits. As a premier global OEM Gas Control Valve manufacturer, our design philosophy combines physical structural durability with smart IoT-enabled telemetry to achieve zero-leakage tolerances.
Utilizing high-performance solenoid coils and optimized return springs to achieve valve closure in under 1.0 second. Essential for mitigation during immediate gas leak scenarios.
Our solenoids and pilot mechanisms carry international approvals including Ex d IIC T6 Gb, making them safe for Zone 1 and Zone 2 hazardous gas environments.
Engineered with compatible seal elastomers like NBR, FKM, and FFKM to handle Natural Gas, LPG, Biomass, and increasingly challenging Hydrogen (H2) blended gas streams.

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 such as CE and 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 acts as 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.
Procurement engineers and industrial distributors prioritize structural reliability, material verification, and regulatory compliance. Our OEM framework is designed to resolve common friction points in international valve procurement.
We work with diverse metals to meet high mechanical load requirements:
Modern control centers require integrated loop automation. We support custom electrical variations:
Gas safety demands customized solutions based on operating context. We engineer systems designed for specific vertical applications.
Designed for environments with corrosive H2S gas and volatile organic compounds (VOCs). Features robust Ex-d containment, corrosion-resistant SS316 construction, and SIL-2 safety loop capability to prevent catastrophic industrial pipeline explosions.
Solutions for urban gas distribution, city gates, and pressure reduction stations. Includes low-pressure drop valves, wireless pipeline health telemetry (smart pressure monitoring), and automatic mechanical shut-off systems that trigger during seismic activity.
Engineered for fuel-feeding systems of boiler assemblies and automotive paint ovens. Features high-cycling solenoid configurations, precision flow regulation (needle and proportional adjustments), and fast shut-off to manage burner safety limits.
We ensure our safety valves perform reliably through a rigorous testing infrastructure.
Operating under international quality standards requires comprehensive verification. Our CNAS-accredited calibration laboratories test raw materials, mechanical tolerances, and finished products.
We support regional distributor networks with complete technical documentation, including compliance reports, custom serial trace numbers, ATEX / IECEx certificates, and SIL verification reports.
From a localized startup to a global leader in intelligent gas safety valve manufacturing, explore our major company milestones.
Established on April 17th, 2003. Launched our first-generation gas leak alarm and fire fighting products, laying the foundation for our safety technology portfolio.
Initiated dedicated production of gas safety valves and expanded our OEM business. Moved offices to the Longtan Industrial Park to support manufacturing scaling.
Achieved a milestone of 10 million cumulative gas detector sales. Moved to our Chengdu factory building, finalized national sales networks, and launched fire power monitoring systems.

Deyang factory operations commenced. Launched wireless detection lines, urban pipeline network monitoring platforms, and our new line of AI-integrated safety valves.
As energy industries transition toward automation and sustainable fuels, gas control valve designs are changing. We focus our R&D on key growth areas:
We build micro-sensors directly into valve casings, tracking real-time status, static pressure, ambient temperature, and coil health. Modbus/RTU, LoRaWAN, and NB-IoT protocols transmit this status data to central command consoles.
Using predictive analytics, our control valves identify abnormal pressure changes, distinguishing micro-leaks from typical flow fluctuations. This supports automated shut-offs to prevent system failures.
To support the global shift toward hydrogen energy, we test and verify our valves for high-percentage hydrogen blends, focusing on material embrittlement, seat leakage, and ignition safety.
