Advanced shut-off solenoids calibrated for low leakage and high responsiveness in industrial and domestic gas lines.
Vietnam is experiencing an unprecedented industrial expansion. High-tech manufacturing hubs in industrial parks like VSIP (Vietnam-Singapore Industrial Park) in Binh Duong, Bac Ninh, and Hai Phong, alongside manufacturing hubs in Dong Nai and Vung Tau, are driving a massive surge in energy demand. Natural Gas, Liquefied Petroleum Gas (LPG), and Liquefied Natural Gas (LNG) have become vital fuels powering thermal processing, chemical synthesis, metallurgical furnaces, and industrial boilers.
With this rapid transition comes rigorous regulatory frameworks. The Vietnamese Ministry of Construction and the local Fire Prevention, Fighting and Rescue Police Department (Cục Cảnh sát PCCC và CNCH) have steadily tightened regulations on factory safety, gas pipeline systems, and leak containment. High-fidelity, explosion-proof gas solenoid valves and intelligent monitoring equipment are no longer optional—they are critical, compliance-mandated components to safeguard assets, personnel, and production continuity.
Founded in 2003, Xinhaosi has spent over two decades pioneering advanced electronic detection and gas control technology. We utilize cutting-edge manufacturing processes to turn invisible hazards into visible, controllable safety metrics.
We provide customer-focused products and services to safeguard the operations of factories, commercial kitchens, metropolitan gas grids, and homes. Backed by our automated production facility, we deliver high-reliability components featuring flame-retardant coils, high-strength aluminum alloy and brass bodies, and seamless integration with remote PLC telemetry.
For Vietnamese industrial projects requiring strict compliance, our team assists from engineering specification selection to on-site testing procedures.
Ensuring end-to-end prevention by linking real-time atmospheric sensing with immediate emergency valve shut-off.
A gas solenoid valve is an electro-mechanically operated valve designed to control the flow of natural gas, propane, LPG, or biogas. The core component comprises an electromagnetic solenoid coil, which, when energized or de-energized, shifts a plunger to either block or permit flow through the valve body.
Normally Open (NO) valves require an electrical pulse to shut off and must be manually reset once the emergency is resolved, preventing accidental gas re-entry. Normally Closed (NC) valves require constant power to stay open, shutting down instantly if power is lost.
Given the volatile nature of gas environments, the solenoid coil is encapsulated in heavy-duty flameproof housing (Ex d IIC T6). This ensures that any spark generated internally by the electrical contacts cannot ignite the surrounding atmosphere.
Equipped with optimized return springs and high-permeability magnetic iron cores, our valves actuate in under 0.5 seconds upon receiving a signal from detector controllers or fire alarm systems.
Sourcing directly from our state-of-the-art Chinese manufacturing facilities offers unparalleled advantages for Vietnamese industrial buyers, EPC contractors, and local distributors:
Engineered to withstand harsh environments, high humidity, and complex gas compositions.
Installed at the gas intake of boilers and furnaces in ceramic, steel, and textile mills throughout Binh Duong and Dong Nai. The solenoid valve integrates directly with burner control systems to block gas flow immediately if a flame-out is detected.
Mandated in high-rise commercial centers, international hotels, and resort complexes in Da Nang, Hanoi, and Saigon. Combines with gas sensor arrays to auto-isolate central LPG cylinders in the event of kitchen gas line damage.
Used by local gas utility operators to manage neighborhood gas feeds and pressure reduction stations, allowing remote shut-off via SCADA control centers when pressure spikes or ground movement is detected.
From detection to isolation, our integrated ecosystems include high-precision sensors, intelligent controllers, and robust mechanical shut-off valves. Build a secure industrial environment with our certified protective gear.
