High-precision safety infrastructure elements designed for global industrial, commercial, and residential networks.
A technical overview of the mechanics, design, and structural parameters that define professional solenoid valve performance.
Within hazardous environments, the speed and reliability of gas flow shutdown are determined by a single critical component: the solenoid actuator. A solenoid valve coil functions by generating a highly concentrated electromagnetic field when energized. This magnetic flux overcomes mechanical resistance and internal spring tension, shifting the metallic plunger to either open or close the gas flow path within milliseconds.
At Xinhaosi, our engineering team optimizes every variable of the solenoid development cycle. We select premium electromagnetic steel with high magnetic permeability and minimal remanence to prevent the sticking issues common in low-tier alternatives. Our coils are wound using high-grade insulated copper wire (up to Class H rating, which withstands temperatures of up to 180°C) and encapsulated in high-impact, flame-retardant polymers. This robust design guarantees consistent duty cycles, minimal power losses, and protection against moisture ingress, chemical exposure, and mechanical vibration.
Whether configuring a pulse-type latching solenoid for low-power consumer applications or a heavy-duty, continuously energized solenoid for petrochemical plants, our systems are engineered for long service life. By integrating advanced thermodynamic profiling and electromagnetic simulation into our R&D phases, we produce solenoid actuators that maintain rapid response speeds and safe operation under high pressure and thermal fluctuations.

A chronological review of our key growth milestones and technological achievements.
Established on April 17th, 2003. Launched the first generation of gas leak alarm and fire fighting products, laying the foundation for our safety control designs.
Started gas safety valve production and expanded our international OEM business. Relocated our corporate office to the Longtan Industrial Park to support this growth.
Achieved 10 million units in gas detector sales. Moved into the Chengdu factory building, established our sales and service network across China, and launched fire power monitoring system products.
Launched our self-developed IoT platform alongside automatic alarm, emergency lighting, and evacuation systems. Obtained our high-tech enterprise certificate and became an official supplier to China’s top 5 gas groups.
Began construction of the Deyang factory, established the Petrochemical & International Business Division, and was awarded the title of Sichuan Provincial Technology Center.
Completed construction of the Deyang factory and began full operations. Launched urban gas pipeline network monitoring systems, wireless detection systems, and AI safety valve products to support future networks.
The evolution of flow control towards AI, IoT, and ultra-low power consumption.
The industrial landscape demands solenoid systems that offer more than basic open/close functions. The future lies in intelligent, diagnostic-capable actuator networks. Xinhaosi is leading this evolution by integrating micro-sensors directly within the solenoid housing. These sensors monitor magnetic flux variance, coil temperatures, and mechanical response times in real-time, helping to identify wear before an actual shutdown failure occurs.
Our upcoming product generation focuses on three development areas:
Tailoring control and safety architectures for complex industrial applications.
Explosion-proof solenoids certified to ATEX and IECEx standards. Built with robust mechanical housings to withstand corrosive hydrocarbon vapors, high pressures, and extreme environmental temperatures.
Large-scale, emergency shutdown valves (ESDVs) connected to city gates and distribution hubs. Engineered for reliability during emergency events such as seismic activity or line pressure drops.
Highly compact, cost-effective shut-off valves for kitchens, boilers, and utility rooms. Optimized for high-volume production, low maintenance, and quick installation with standard household gas alarms.
Meeting international testing frameworks to ensure safe operation worldwide.
Deploying flow control equipment internationally requires strict adherence to diverse local standards. Xinhaosi design teams address this compliance requirement from the initial project design phase. Our manufacturing operations comply with ISO 9001:2015, and our gas detection systems and solenoid valves carry international certifications, including the European CE mark and SIL (Safety Integrity Level) ratings.
Our CNAS-accredited calibration laboratories issue certificates traceable to international testing bodies under the ILAC-MRA framework. This ensures that our test reports are recognized by European, North American, and Asian regulators, facilitating easier market access for our partners. Through our local distributor and technician networks, we provide ongoing support, including technical assistance, on-site commissioning, and regulatory calibration. This helps ensure your gas safety systems comply with all relevant safety standards.
How our dual production bases in Chengdu and Deyang guarantee delivery times and quality.
Global supply chains require both speed and reliability. Xinhaosi addresses this through our advanced Deyang Smart Factory and Chengdu HQ facility. Operating as a Factory 4.0 model, our manufacturing floors utilize automated coil-winding machines, smart robotic assembly cells, and computerized inspection stations that test every valve for leakage and magnetic force before shipping.
By producing our electronic control boards, winding our own coils, and machining our valve bodies in-house, we reduce dependency on external component suppliers. This vertically integrated manufacturing model helps insulate partners from global material delays, stabilizes pricing, and shortens OEM prototype lead times. Through our automated inventory management, we maintain safety stocks of raw materials and sub-assemblies. This enables us to fulfill large-scale orders on time, even during peak production cycles.
