Explore our high-performance industrial gas detectors, smart controllers, and integrated emergency shut-off solenoid valves manufactured under strict QA compliance.
The industrial landscape is undergoing a radical transition from simple mechanical control to safety-instrumented systems (SIS) that demand smart response features. Within this framework, 2-way/2-position solenoid valves (commonly referred to in critical flow operations as "2 solenoids" or dual-stage control modules) function as the ultimate security gates in pipelines carrying natural gas, LPG, and toxic chemical fluids. Historically, basic solenoid valves acted solely on binary signals without feedback loops. Today, the demands of Industry 4.0 dictate that solenoids display self-diagnostics, low power hold coils, and compatibility with safety plc protocols.
Modern engineering designs optimize these solenoid valves to operate reliably under extreme conditions. A standard 2-position safety valve needs to handle high operating pressures while retaining a low pressure-drop coefficient across the orifice. Through precision-engineered electromagnetic coils, these units establish instantaneous closure when sensor arrays detect gas leaks or systemic anomalies.
Safety requirements across hazardous zones demand robust electrical and mechanical reliability:
B2B procurement professionals require more than standard components; they seek strategic OEM/ODM partnerships.
Compliance is critical in international procurement. Factories must adhere to strict regulatory standards, ensuring products carry certifications like CE, SIL (Safety Integrity Level) rating, ATEX/IECEx, and ISO 9001 quality system stamps.
For chemical and urban gas systems, brass, aluminum alloy, and stainless steel bodies must undergo rigorous stress-corrosion tests. Traceability reports ensure no counterfeit alloys compromise pressure containment.
We provide tailormade engineering: custom voltage ratings, dedicated terminal boxes, flameproof lead wires, and specialized seals (NBR, FKM, VMQ) to withstand unique localized ambient temperatures.
"Purchasing teams optimizing their inventory systems value suppliers that offer robust technical validation and testing services alongside manufacturing capabilities. A reliable supplier acts as an extension of your own engineering department."

Every item we manufacture undergoes rigorous quality control tests, and every service we provide is backed by our professional technical team, fully embodying our unwavering commitment to safeguarding gas safety across both industrial workplaces and residential environments, and striving to build a safer world with sustainable gas safety technologies.
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.
Our systems operate reliably in critical safety infrastructures across diverse industries.
We supply integrated gas safety systems, pairing household gas detectors with fast-shutoff solenoid valves. When a sensor detects gas at low concentrations, it triggers the solenoid valve to isolate the supply line immediately.
Our explosion-proof gas detectors (GTYQ series) and heavy-duty industrial solenoid valves provide robust containment. They are built to withstand corrosive atmospheres and high operating temperatures typical of refineries.
We offer low-power latching solenoid systems integrated with RTUs and remote telemetry. This allows utility companies to isolate entire pipeline branches instantly from a central control room during emergencies.
From an innovative startup to a global leader in gas safety solutions, explore our path of technological development.
Our journey began with a clear focus: designing reliable gas safety products to address critical industrial safety gaps.
As standard gas infrastructure transforms into decentralized, automated networks, our engineering teams are developing next-generation solutions. Our technical roadmap focuses on three main pillars:
As the world transitions to hydrogen-blended natural gas, we are re-engineering solenoid seals to handle low molecular weight hydrogen and prevent embrittlement.
Developing low-power, energy-harvesting actuators designed for remote geographical regions. These units operate on internal batteries charged by ambient thermal or solar energy.
Utilizing real-time current measurements and valve stroke times to calculate seal wear, helping operators perform predictive maintenance before physical failures occur.
Xinhaosi does not just follow industry standards—we help define them. As a main drafting organization for the Chinese National Standard of Gas Solenoid Valves, we understand the regulatory challenges OEMs face.
Our CNAS testing center ensures every batch of raw materials is evaluated under simulated environmental extremes. By integrating real-world performance data with our design iterations, we deliver reliable solutions that protect both industrial workplaces and residential spaces.
