Explore our leading safety control equipment, designed to work seamlessly with industrial piping and 1 inch gas solenoid valve mechanisms.
Within complex thermal systems and industrial gas transmission pipelines, the 1 inch gas solenoid valve (DN25) acts as the vital point of control for safety and automation. Its strategic sizing is the benchmark standard for medium-flow systems, bridging the gap between small-diameter domestic lines and high-capacity main distribution grids.
Global demand patterns reveal that procurement departments look for reliable suppliers capable of satisfying stringent safety integration. These valves must interface directly with safety warning arrays—such as industrial gas sensors and smart building management frameworks (BMS)—guaranteeing immediate shut-off in the presence of combustibles.

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.
How our 1 inch gas solenoid valve and related monitoring products function together to protect complex distribution infrastructures.
Integration of combustible gas detectors (such as the JT-AT2018 series) and a 1 inch gas solenoid valve positioned at the gas inlet line. Upon detecting abnormal gas levels, the detector triggers the valve instantly, cutting off the gas supply and sounding alarms before combustion levels can reach critical limits.
In highly sensitive zones, we combine our AT0502/AT0601 explosion-proof detectors with heavy-duty solenoid valves. The interlock control boxes manage multiple sensors and valves across long distances, ensuring complex setups can shut down isolated pipe systems without affecting the rest of the factory.
By using wireless pressure monitors like the AT0635, municipal gas systems can monitor flow pressure drops in real-time. If pressure drops suddenly, suggesting a pipeline breach, remote control systems trigger the solenoid shut-off valves, keeping urban populations and infrastructures safe.

The transition from traditional mechanical-electric shut-off mechanisms to intelligent, sensor-integrated valves is changing the safety landscape. By integrating flow monitoring and pressure analytics directly inside the valve block, we minimize additional pipe fittings, reduce pressure drops, and eliminate leaks.
Our engineering roadmap focuses on low-power hold technology, ensuring that normally open valves consume zero power during standard operation, drawing energy only during the brief milliseconds required for safety-actuated shut-off.
Our engineering experts address common questions about selection, installation, and operation of 1 inch gas solenoid valves.
Normally Open (NO) valves require an electric impulse to shut off and stay closed until manually reset. This makes them ideal for gas safety systems, preventing a power outage from cutting off gas supplies. Normally Closed (NC) valves require constant electrical power to stay open, shutting automatically if power fails, which is preferred in automatic combustion control systems.
A 1 inch line balances flow volume with compact installation profiles. It provides sufficient gas flow for multiple commercial burners and ovens without causing significant pressure drops, while keeping the solenoid mechanism small enough to fit within utility cabinets or ceiling panels.
Yes. With over 20 years of experience, we provide flexible OEM and ODM services. We customize body metals, thread standards (NPT, BSP, or Flanged), coil voltages (12VDC, 24VDC, 220VAC), and explosion-proof ratings to match the specific safety requirements of your target market.
Our laboratory subjects valves to strict tests: pressure resistance testing, leakage checks, opening/closing response speed timing, high/low-temperature aging cycles, and flameproof structural validation. All test data is fully traceable, ensuring compliance for international market distribution.
