Hot Selling Safety LPG CNG Gas Cylinder Filling Valve for Autogas Conversion Control System Brass
CNG Filling Valve is the valve through which the CNG is refilled in the gas cylinder. This CNG filling valve is manually operated, made of forged brass body, mechanized with latest CNC lathe machines. It serves as a critical refill component for autogas conversion control systems for vehicles running with compressed natural gas.
The plug-type manual structure provides stable and reliable operation during cylinder refilling procedures. Hot forged brass body processed by CNC machining ensures great sealing performance and long-term service life. It supports wide-range ambient temperature adaption and can endure high working pressure for cng gas cylinder applications.

FAQ
Q: What is this plug-type CNG filling valve used for?
A: This manual filling valve is mounted on CNG gas cylinders, specially used for refilling compressed natural gas for autogas converted vehicles, as a key part of gas filling control system.
Q: Why choose hot forged brass material for CNG filling valves?
A: Hot forged brass offers high pressure resistance, good corrosion resistance and excellent machinability. After CNC processing, it achieves tight sealing performance to prevent gas leakage during filling.
Q: What does 1100° opening/closing angle mean?
A: It is the total rotation angle of the manual tap. The large rotation angle makes opening and closing operations smoother and helps users control gas flow status more precisely.
Q: What are the connection sizes of this filling valve?
A: Input and output connections are Φ6mm and M12x1 thread, compatible with mainstream CNG pipelines and fittings in cng modification industry.
Q: Can this valve work under extreme cold or hot environment?
A: Yes. The operating temperature covers -40℃ to 120℃, which can adapt to low-temperature cold areas and high-temperature working environments.
