CNG Brass Gas Cylinder Relief Valve For NGV CNG Conversion System
CNG brass gas cylinder relief valve acts as a critical shut-off fitting for vehicle-mounted compressed natural gas cylinders, widely adopted in natural gas vehicle retrofitting projects. Many conversion garages and system integrators select this brass cylinder valve for its robust mechanical strength, excellent high-pressure resistance and stable sealing performance. It controls gas on-off flow between CNG storage cylinder and downstream gas supply pipeline for NGV conversion kits.
This brass CNG cylinder valve is rated for 20 MPa nominal working pressure, with DN 4 mm internal flow channel. Both outlet joint thread and cylinder-side joint thread adopt Type Hole 6 connection, providing reliable tube crimp connection for high-pressure CNG pipelines. This unit is manufactured without integrated temperature-pressure safety device. The brass material body delivers good anti-corrosion performance, suitable for long-term vehicle-mounted working conditions of CNG fuel systems.
