Explore our industrial and household grade safety components engineered for seamless integration and milliseconds-grade shutdown response times.
Founded in 2003, Xinhaosi has spent over two decades establishing itself as one of the most influential and reliable brands in the gas safety industry. Our production facilities deploy advanced electronic detection technology to make unknown gas leak risks clear and visible.
We provide customer-focused products and engineering-grade services designed to safeguard the safe operation of industrial plants, commercial kitchens, urban gas distribution infrastructures, and residential settings worldwide. Powered by Industry 4.0 production systems, our Chinese factories deliver robust, precise, and certified gas safety valves and detector components.
Integrating high-reliability 1" gas shut-off valves with state-of-the-art detectors to build an impenetrable shield against hazards.
Designed for oil & gas, petrochemical, and manufacturing operations. Safeguarding critical infrastructure from hazards with advanced precision sensing systems.
Ensuring residential peace of mind and commercial kitchen safety. Delivering intelligent sensing technologies that detect gas leaks before they escalate into emergencies.
Shutting off hazards at the source. Engineered to perform reliably under high vibration, temperature extremes, and rapid duty-cycle requirements.
Providing municipal smart sensing infrastructure for citywide pipelines. Connecting localized shut-off valves with central SCADA platforms for immediate response.
For safety engineers and procurement officers worldwide, a 1" gas shut-off valve is not merely a pipeline component. It is the primary boundary between controlled fuel delivery and potential catastrophe. At Xinhaosi, we develop these valves with deep focus on materials engineering, electromagnetics, and functional safety systems.
Our 1" valves leverage high-density electromagnet coils that actuate within <0.5 seconds when triggered by gas detection sensors. Available in pilot-operated models (optimized for large flow rates) and direct-acting configurations (designed for zero-pressure startup).
Machined from high-tensile brass alloys or grade 316 stainless steel to ensure zero porosity. Internals feature VITON or NBR seal matrices that resist chemical degradation from common natural gas impurities like hydrogen sulfide (H2S).
Our industrial shut-off solenoids comply with Ex d IIC T6 Gb explosion-proof requirements. They are engineered to suppress potential electric sparks internally, making them suitable for hazardous Zone 1 and Zone 2 environments.

Xinhaosi operates a state-of-the-art production hub in China, utilizing smart automation and vertical supply integration. By managing everything from raw billet forging and CNC precision turning to automated coil winding and leak detection, we guarantee uniform quality and competitive lead times.
Providing custom solutions that comply with international regulatory frameworks, safety ratings, and regional industrial requirements.
Our 1" gas shut off valves are engineered to align with European safety standards (EN 161) for automatic shut-off valves for gas burners and gas appliances. This certification pathway guarantees that the valve closes safely and securely in the event of a power outage or automated trip signal.
For chemical and petrochemical installations, we offer valves with SIL (Safety Integrity Level) certifications. Our design features spring-assisted closing mechanisms that require no electrical energy to return to a safe position, ensuring high reliability in emergency shutdown (ESD) systems.
To safely manage risks, our industrial solenoids are housed in rugged, flameproof enclosures. This isolates potential ignition sources from explosive atmospheres containing methane, propane, or volatile organic compounds (VOCs).
We supply specialized mounting configurations, custom voltage inputs (220V AC, 24V DC, 12V DC), and specific connection threads (NPT, BSPT, or Flanged) to fit existing gas distribution manifolds and pipeline designs.
Working alongside major gas utility organizations and safety system integrators to secure energy infrastructures.

Most of our 1" gas shut-off solenoid valves are configured as "normally closed" or "auto-closing manual reset." This design ensures that if power is lost, the valve closes instantly to prevent uncontrolled gas flow, meeting critical safety fail-safe requirements.
We use heavy-duty forged brass and high-grade stainless steel to resist mechanical stress and chemical degradation. Additionally, our industrial valve solenoid housings carry ATEX/IECEx explosion-proof certifications, allowing safe operation in Zone 1 and Zone 2 environments.
Yes. Our 1" valves are designed to connect with our gas controllers and detectors, including the AT0602 and JT-AT2004B series. In the event of a leak, the detector sends a low-voltage pulse to shut off the valve in milliseconds.
Our residential and commercial valves are rated for low-pressure lines up to 50 kPa. For industrial and transmission applications, we manufacture valves that operate at pressures up to 1.6 MPa (PN16).
Yes, we provide extensive custom options for global procurement teams. We can customize threat types (NPT/BSPT), flange dimensions, input voltages (AC/DC), body materials, and regulatory certifications to match your project requirements.
Complete safety coverage with our integrated control panels, input modules, and detection systems.
