Analyzing critical safety systems within industrial gas transit, urban distribution grids, and high-capacity manufacturing facilities.
Within modern industrial distribution frameworks, gaseous fuels such as natural gas, methane, and liquefied petroleum gas (LPG) are fundamental sources of thermal energy. However, their physical properties demand uncompromising infrastructure safety. An OEM 1 Inch Natural Gas Shut Off Valve represents a key security component, serving as a first-line barrier against system leaks, structural ruptures, and hazardous pressures.
Globally, government bodies such as OSHA, the European Union's ATEX directives, and the National Fire Protection Association (NFPA) mandate automatic, reliable isolation valves at key interfaces. Whether shutting down industrial burners, shutting off supply lines in smart-meter networks, or responding to automated sensor alerts, the response time of a 1-inch valve directly determines the risk level of the facility.
Xinhaosi's specialized engineering ensures that these valves provide rapid closure capabilities in under 1 second. This level of reliability is critical to prevent hazardous accumulations of gas and protect both industrial assets and human life.

Over the past two decades, we have built a comprehensive production and service system that integrates cutting-edge R&D, intelligent manufacturing with advanced automation equipment, digital marketing across global channels, and professional after-sales support with an experienced technical team.
We provide flexible OEM/ODM services, supported by CNAS-Accredited laboratory calibration services that meet rigorous international standards. Our diversified product portfolio covers industrial & residential gas detection and alarm systems, industrial & household gas solenoid valves, and urban gas pipeline network monitoring systems—all engineered to perform in demanding environments under strict safety requirements.
We produce and sell tens of millions of units annually, catering to safety-critical sectors including oil & gas exploration, petrochemicals, urban gas distribution, automotive manufacturing, pharmaceuticals, steel production, and beverage processing. Guided by the core mission of "Making Gas Safety Accessible Everywhere," we deliver high-performance, reliable products and customized solutions to protect workplaces and communities worldwide.
A rigorous inspection of our safety certifications, standardizations, and proprietary engineering designs.
Adhering to ISO9001 quality management system standards, Xinhaosi's core products have obtained a full range of authoritative certifications, including national compulsory Product Certification (CCC), explosion-proof certification, fire product certification, and international approvals such as CE and SIL.
Xinhaosi holds honors such as "National Quality Integrity Benchmark Enterprise" and is a member of the China Fire Protection Association. We served as the main drafting organization for the national standard of solenoid valves, demonstrating our expertise and leadership in safety technology.
Our in-house laboratory is accredited by the CNAS and recognized internationally under the ILAC-MRA framework. Operating under ISO/IEC 17025 standards, it provides traceable calibration and testing for gas safety equipment, ensuring global compliance and rapid market access.
In intellectual property, Xinhaosi has built a robust innovation system with over 50 patents and software copyrights. This includes a graphical monitoring system for gas detection that enables predictive maintenance based on historical data—reducing equipment failure rates by over 30%. Additionally, we pioneered a solenoid valve with integrated flow monitoring, and the only maximum-point gas leakage monitoring system certified by the Ministry of Public Security in China, reinforcing our leadership in technical R&D.
Delivering tailored flow control engineering to meet diverse regional safety codes and operational demands.
As a leading OEM 1 Inch Natural Gas Shut Off Valve Supplier, Xinhaosi recognizes that a single design cannot meet every operational standard. Our OEM/ODM divisions customize shut-off systems to match regional requirements and application environments:
We configure parameters such as connection threads (NPT, BSPT, Flanged), input voltages (DC12V, DC24V, AC220V), and seal materials (NBR, Viton) to match the chemical profiles of local natural gas supplies and regional climate challenges.

| Valve Size | 1 Inch (DN25) |
| Pressure Range | 0 to 100 kPa / Up to 0.6 MPa (High Press) |
| Closing Speed | < 0.5 to 1.0 Second |
| Certifications | CE, SIL, CCC, CNAS Laboratory Calibration |
A look at Xinhaosi's growth from a safety startup to an international provider of smart gas monitoring solutions.
Established on April 17, 2003. We launched our first-generation gas alarms, expanded into gas safety valve production, and began developing our OEM business in the Longtan Industrial Park.
Achieved sales of 10 million gas detectors, completed our China-wide sales and service network, launched our self-developed IoT safety platform, and became an official supplier to major gas providers.
Opened our smart factory in Deyang, launched urban pipeline monitoring systems, and developed wireless detection devices alongside AI-integrated safety shut-off valves.
Addressing common technical and regulatory questions raised by project engineers, facility managers, and OEM clients.
Normally Open (N.O.) solenoid valves remain open without electrical power and require a pulse or sustained signal to trigger shut-off. This configuration is widely used in municipal gas lines to prevent valve closure during power outages. Normally Closed (N.C.) valves require constant power to stay open, offering fail-safe closure immediately if system power fails.
A 1-inch valve balances flow capacity (Cv) and line pressure drops, making it suitable for feeding multi-device systems like commercial kitchens, mid-sized boilers, and sub-metering points in multi-family housing. Using this standard sizing helps prevent pressure fluctuations during peak usage.
CNAS accreditation indicates that Xinhaosi operates under ISO/IEC 17025 calibration standards, which are recognized globally under the ILAC-MRA agreement. This accreditation ensures that our test reports, safety parameters, and leak-integrity guarantees comply with key regulatory frameworks worldwide, streamlining site approvals.
Yes. Our solenoid shut-off valves are designed to interface with systems like the JB-TB-AT2020LH Controller or GT-AT0617 monitoring systems. In the event of a gas leak detection, the controller outputs a brief electrical pulse to trigger immediate, automatic shutdown of the gas line.
Our industrial valves feature heavy-duty, flameproof enclosures and encapsulated coils, designed to meet international Ex d and Ex ib standards. These designs prevent internal electrical sparks or thermal buildup from igniting ambient combustible gases in the surrounding workspace.
Xinhaosi provides comprehensive customization, including tailored body materials (brass, aluminum, stainless steel), custom thread formats (NPT, BSP, Flanged), specific coil voltages (DC12V, DC24V, AC220V), and integrated status indicator signals, along with custom branding and packaging.
