Brass Manual CNG Filling Valve for Autogas Systems
This manually operated valve is listed for CNG filling circuits. The body is described as hot-forged brass with CNC machining. Confirm the exact valve design, installation position and connection drawing before ordering.
This listing specifies compressed natural gas. Do not assume LPG suitability or compatibility with every cylinder or filling connection. Match the valve to the documented system requirements.
Technical Specifications
The following values are listed in the product information. Confirm their definitions and supporting documentation for the supplied valve.

| Opening and Closing Travel | Request the verified operating angle or number of turns |
Will the Valve Fit Your Installation?
Connection dimensions alone do not establish compatibility. Request the complete drawing and identify the purpose of each port before selecting fittings.
Port assignment: Identify inlet, outlet and intended flow direction.
Tube connection: Confirm whether Φ6 mm refers to tube outside diameter or another dimension.
Thread: Confirm the M12 × 1 connection, mating fitting and sealing arrangement.
Mounting: Verify support, orientation, clearance and access for manual operation.
System role: Confirm whether the component is an inline filling valve, filling interface or another valve arrangement.
A filling valve should not be assumed to be a cylinder-mounted valve. Use the installation drawing to confirm its location and function within the CNG circuit.
What Do the Pressure and Flow Values Establish?
The listed 26 MPa is a working-pressure claim that requires verification. Request the rated temperature conditions and the applicable test or approval documents. Do not treat a test pressure as a continuous operating rating.
A flow area is not a filling-rate guarantee. Actual flow depends on pressure difference, gas conditions and the complete filling circuit. Request measured flow data if filling performance is a purchasing requirement.
Rated operating pressure and temperature conditions
Pressure-test method and acceptance criteria
Leak-test pressure, duration and permitted leakage
Flow-test gas, pressure conditions and measurement units
Operating travel and any specified torque limits
Which Quality Documents Should Buyers Request?
Material and machining descriptions do not prove leak performance. Request inspection records covering the supplied valve model.
Identification: Product reference and batch or serial number.
Dimensions: Connection and sealing-surface inspection results.
Leak testing: Test medium, pressure, duration and result.
Pressure testing: Test conditions and acceptance limits.
Operation: Opening, closing and repeated-operation checks where specified.
Documents: Applicable report or approval reference and covered model.
Approval scope must match the valve and destination requirements. Review our certification information and request applicable documents before ordering.

Frequently Asked Questions
Can this valve be used with LPG?
LPG suitability is not established by this listing. Request a valve documented for the required fuel and operating conditions.
Does it connect to every CNG filling nozzle?
No universal filling-interface compatibility is established. Confirm the intended mating interface and connection drawing. A pipe thread specification does not identify a filling-nozzle standard.
How far must the manual control turn?
Use the operating travel specified in the verified drawing. Request the angle or number of turns and any torque limits. Do not infer the operating method from appearance.
Does forged brass guarantee a leak-free valve?
No material description alone establishes sealing performance. Seals, dimensions, assembly, operating conditions and inspection results must also be reviewed.
Who should install and inspect the valve?
Qualified CNG technicians should perform installation and commissioning. Follow the component instructions and applicable local requirements. Request approved inspection intervals and service procedures.
Request a Manual CNG Filling Valve Quotation
Send the connection and application details for a compatibility review. Include intended installation position, required pressure and temperature, fitting drawings, destination country and quantity.
Confirm supply scope before payment. Request the exact valve reference, mating fittings, operating instructions, price, warranty, test documents and delivery lead time.
