Our elite product line integrates precision engineered detectors, flame monitors, and high-performance gas pressure transmitters to support complex pipeline installations.
Within the spectrum of global industrial and commercial flow management, the 1-inch solenoid valve stands out as a critical cross-sector sizing standard. Used extensively to regulate flow velocities in medium-pressure pipelines, a 1-inch valve delivers the optimal balancing point between volumetric gas flow rate (Cv value) and responsive structural design. From process automation in petrochemical operations to fire prevention infrastructure in residential complexes, choosing a high-performance 1" solenoid valve ensures secure control over flow dynamics.
As a leading OEM Solenoid 1 Inch Manufacturer & Factory, Xinhaosi focuses on engineering excellence, manufacturing valves that are highly resistant to moisture, physical impact, and environmental wear. Our specialized engineering methodologies allow for rapid custom integration to conform directly to the precise requirements of our international partners.

Our vision integrates smart hardware with IoT connectivity to meet shifting global safety mandates.
The standard gas safety solenoid valve is transitioning from a reactive safety shutdown tool into an interactive, cloud-connected terminal. Xinhaosi is at the forefront of this shift, integrating micro-sensors directly within the 1-inch valve body to actively measure pressure, micro-leakages, and solenoid temperature.
By using low-power IoT networks (NB-IoT, LoRaWAN, and Zigbee), these smart valves can communicate with building management systems (BMS) and public gas monitoring dashboards, permitting automatic diagnostic reports and remote shutoffs before emergency levels are crossed.
Global environmental mandates, such as the EU RoHS Directive and REACH regulations, demand clean production and lead-free alloys. Xinhaosi’s engineering team has designed lead-free brass and high-durability anodized aluminum 1-inch solenoid valves that exceed environmental standards.
Additionally, we utilize high-precision CNC machinery and automated assembly systems at our new Deyang factory to lower carbon footprints and minimize raw material waste during volume manufacturing.
