Direct-From-Manufacturer Explosion Proof Combustible Gas Detectors, Advanced Loop Controllers, and Specialized Safety Terminals
In global gas distribution pipelines, petrochemical plants, and large-scale industrial heating networks, the Low Pressure (LP) Solenoid Valve is the critical safety system responsible for controlling medium flow. These mechanical assemblies rely on electro-magnetic principles to trigger immediate open/close sequences. Whether managing Liquefied Petroleum Gas (LPG), vaporized propane, or natural gas blends, maintaining low operational pressure drops while keeping tight, bubble-tight seal integrity is a fundamental challenge.
Modern commercial burner setups, industrial kilns, and multi-occupancy utility zones utilize LP valves to interface with emergency safety controls. By shutting down gas flow in milliseconds when an emergency trigger sounds, these valves prevent gas accumulation, fires, and explosions. As a dedicated LP solenoid valve manufacturer, Xinhaosi integrates advanced electromagnetic actuators with premium, corrosion-resistant housings. This design delivers reliable shutoff performance even in low-pressure, high-flow environments.
With modern energy networks increasingly relying on automation, today's LP solenoid valves must serve as active, intelligent nodes. They feature integrated position indicators, fail-safe manual resets, and low-power coils designed to prevent heat generation during continuous operation.
Ensuring absolute gas safety across industrial, municipal, and residential installations worldwide
Established in 2003, Xinhaosi stands as an influential and trusted brand in the global gas safety and control sector. Over twenty years of steady development, we have built an integrated ecosystem that covers advanced R&D, highly automated intelligent manufacturing, global digital distribution, direct technical support, flexible OEM/ODM partnerships, and CNAS-accredited calibration services.
Our core portfolio features high-precision industrial and residential gas detection arrays, heavy-duty industrial gas solenoid valves (such as the Normally Closed CT-XF5 Series), and urban gas distribution monitoring systems. With our smart factory production lines, we deliver millions of safety units annually. These systems support demanding industries like oil & gas extraction, petrochemical processing, metallurgy, new energy projects, pharmaceutical labs, and commercial food production.
Under the guiding principle of "Making Gas Safety Accessible Everywhere," our production runs undergo 100% automated pressure testing, leak inspections, and electrical insulation tests. We continue to design solutions that protect lives, optimize uptime, and support compliance with global safety standards.
Xinhaosi is certified to ISO9001 quality management systems. Our gas control systems hold key certificates, including national compulsory Product Certification (CCC), Explosion-Proof Certification, Fire Safety Product Certification, CPA measurement instrument type approval, and international certifications like CE and SIL levels. Notably, Xinhaosi serves as the primary drafting organization for China's national standards on gas safety solenoid valves.

Chronological growth, technical development, and safety innovations from 2003 through the present
Addressing key technical questions from safety engineers, procurement managers, and systems integrators
Normally Closed (NC) valves require continuous electrical power to stay open. If a power outage occurs or the safety system triggers an alarm, the coil de-energizes, and an internal spring automatically closes the valve. This fail-safe mechanism prevents gas leaks from continuing during power losses or system failures.
Direct-acting valves use electromagnetic force to lift the plunger and open the valve seat directly, functioning reliably down to 0 bar pressure. Pilot-operated valves use the inlet line pressure of the gas to hold the valve open or closed. They require a minimum pressure differential but can manage larger flow rates and pipe sizes using smaller, more efficient electrical coils.
Every product batch is tested in our CNAS-accredited calibration laboratory (accredited to ISO/IEC 17025). We conduct explosion-proof flame path testing, cycle endurance tests, and extreme temperature evaluations. Our products also hold CE, SIL, and national Chinese ex-proof safety credentials.
Yes. Our recent product lines are designed to handle natural gas with hydrogen blends (H2NG). By using specialized elastomer seals like FKM or HNBR, we prevent hydrogen embrittlement and gas permeation, keeping systems safe as energy networks evolve.
