Brass CNG Cylinder Valve with Manual or Solenoid Options
This valve listing covers CNG cylinder filling and supply-control applications. Manual and solenoid options are listed. Confirm the exact model, flow arrangement and supplied functions before ordering.
The cylinder connection and protection-device configuration must be verified separately. A similar valve body does not establish compatibility with a cylinder or vehicle installation. Request the dimensional drawing and installation instructions.

| Relief Device | Confirm inclusion, device type, triggering mechanism and supporting documents |
Will the Valve Fit Your CNG Cylinder?
The cylinder mounting interface must match the cylinder specification. Do not treat the listed M12 × 1 pipe connection as the cylinder-neck thread. Confirm each interface on the drawing.
Cylinder interface: Thread type, size, sealing arrangement and installation requirements.
Pipe ports: Inlet or outlet function, thread and mating fitting.
Flow arrangement: Confirm permitted filling and supply paths.
Clearance: Space for the valve, coil, wiring and service access.
Application: Cylinder reference, operating conditions and destination requirements.
The valve is one component of the complete CNG system. Review our conversion kit component guide when checking the installation scope.
Which Coil Voltage Should You Order?
12 V and 24 V must be specified as the correct coil versions. Do not assume one coil accepts both supplies. Check the coil label and technical sheet before connecting power.
Rated voltage and permitted operating range
Rated power and current conditions
Connector type and wiring requirements
Continuous or intermittent duty rating
Control-output compatibility and specified protection
Manual and solenoid functions depend on the valve design. Confirm whether the selected version includes a manual isolation function and how the solenoid is intended to operate.
What Protection Device Is Included?
A relief device must be identified by its actual triggering mechanism. Thermal activation and pressure activation are different functions. Do not describe a temperature-triggered device as general overpressure protection.
The previously listed 110 ±5°C value requires device-specific confirmation. Request the device model, activation specification, test method and installation arrangement before using this value in a purchase specification.
Whether the device is included in the supplied valve
Device type and triggering mechanism
Activation conditions and tolerance
Discharge arrangement and installation requirements
Applicable test or approval documents
Which Inspection Records Should Buyers Request?
Inspection records should cover the ordered valve and its accessories. Material descriptions alone do not establish sealing or protection performance.
Leak testing: Test medium, pressure, duration, acceptance limit and result.
Pressure testing: Test method and limits, distinguished from working-pressure ratings.
Operation: Manual and solenoid functional checks where applicable.
Electrical testing: Coil version, supply conditions and functional results.
Protection device: Applicable activation and qualification records.
Traceability: Model, batch or serial reference and inspection date.
Documents must match the valve configuration and destination requirements. Review our certification information and request applicable product records.
Frequently Asked Questions
Can this valve be used on LPG cylinders?
This listing specifies CNG. LPG suitability is not established. Request a valve documented for the intended fuel, cylinder and operating conditions.
Does a 26 MPa rating mean it fits every CNG cylinder?
Pressure rating is only one compatibility requirement. Confirm cylinder thread, sealing arrangement, temperature conditions, protection-device configuration and applicable documentation.
Can the valve replace a pressure reducer?
A shutoff valve and a pressure reducer serve different functions. Do not assume this valve provides regulated outlet pressure. Confirm its actual functions in the technical sheet.
Does every version include a relief device?
Inclusion must be confirmed in the quotation. Request the device type and supporting documentation for the supplied version.
Who should install and service the valve?
Qualified CNG personnel should perform installation and service. Follow the cylinder and valve instructions and applicable local requirements. Do not adjust or bypass protection devices.
Request a CNG Cylinder Valve Quotation
Send the cylinder and interface details for a compatibility review. Include the cylinder reference, mounting thread, pipe connections, required valve functions, coil voltage, destination country and quantity.
Confirm the complete supply scope before ordering. Request the valve reference, relief-device configuration, technical drawing, inspection documents, price, warranty and delivery lead time.
