High Quality Brass Gas Cylinder Safety Filling Control Valve for LPG CNG Car Natural Gas Pressure Reducing tank Shut off
These valves are designed for the head of CNG cylinders which allow flow both in and out. Both manual and solenoid options available. Most include integrated 's for safety. This high-quality brass cylinder control valve acts as a critical safety component for natural gas vehicle tank systems, supporting gas filling and output flow control for car gas conversion projects.
The valve body adopts hot forged brass material with precise CNC machining, delivering reliable sealing and long-term durability under high-pressure working conditions. Solenoid coil supports DC12V and DC24V power supply, widely compatible with most vehicle electrical systems. Built-in overpressure protection greatly improves safety performance for CNG cylinder applications.

FAQ
Q: What is and what function does it provide?
A: is pressure relief device integrated inside the CNG cylinder valve. When temperature exceeds protection threshold 110±5℃, it will release pressure automatically to avoid cylinder overpressure risks for vehicle safety.
Q: Can I get manual version instead of solenoid electric type?
A: Yes, both manual operation and solenoid electric controlled versions are available for selection to satisfy different modification requirements.
Q: What voltage does the solenoid coil support?
A: The solenoid coil supports DC12V and DC24V with rated power 13W, compatible for most passenger cars and light commercial vehicles.
Q: What is the thread specification of inlet and outlet?
A: Input and output connection is M12x1 thread, compatible with mainstream CNG cylinder piping fittings in industry.
Q: What vehicles and systems can this cylinder valve apply to?
A: This CNG cylinder automatic valve is installed on top of CNG gas cylinders, widely used for natural gas vehicles, car gas conversion and tank shut-off control systems.
