Manual Fuel Isolation and Refueling Connection
This brass CNG filling valve combines a manual on-off handle, an internal non-return valve and a protective dust cap. It is offered as a refueling-port component for compatible vehicle CNG systems.
Replacement selection depends on the valve specification and mating connections. Confirm the refueling interface, outlet fitting, pressure rating, temperature range and mounting dimensions before ordering.

What Does Each Component Do?
Manual handle: Provides manual opening and closing according to the valve operating instructions.
Non-return valve: Is designed to restrict reverse gas flow. Verify its operation using the specified inspection procedure.
Dust cap: Helps keep dirt away from the filling interface when fitted. It is not a substitute for the pressure-retaining valve seal.
Brass body: Forms the valve housing. Material alone does not establish the complete valve's pressure rating or corrosion performance.
Factory and Processing Image
Which Details Are Needed Before Ordering?
A complete connection specification is required for matching. A similar valve shape or vehicle model does not establish interchangeability.
Identification: Existing valve model, markings and photographs.
Filling interface: Mating nozzle specification, connection profile and pressure designation.
Outlet: Thread or tube-fitting dimensions and sealing arrangement.
Operating limits: Required working pressure and temperature range.
Mounting: Installation dimensions, support arrangement and handle clearance.
Supply: Quantity, included accessories and packaging requirements.
The refueling interface must match the dispensing equipment. Confirm the exact connection using product documentation. See our NGV refueling interface comparison for related selection information.
Frequently Asked Questions
Can this valve fit every CNG conversion kit?
No universal fit is established by the product name. Match the interface, outlet fitting, operating limits and mounting arrangement to the specific installation.
What is the rated working pressure?
The pressure rating must be confirmed for the supplied model. Request the datasheet and corresponding valve markings. Do not apply a pressure value from another valve with a similar appearance.
Does closing the handle make the system ready for maintenance?
Handle closure alone does not establish that the system is depressurized. Follow the equipment isolation and depressurization procedure before any service work. A closed section may still contain pressurized gas.
Can threads or packaging be customized?
Bulk-order customization requests can be reviewed. Send the required connection drawing, quantity and packaging specification. Confirm the final configuration and supporting documentation before purchase.
When should the valve be inspected?
Follow the equipment maintenance schedule and investigate abnormal operation. Leakage, visible damage or difficult handle movement requires assessment by a qualified technician. Do not force the handle or continue using a defective valve.
Installation and Inspection
Installation requires a qualified autogas technician and the correct valve instructions. Verify the mating connections, sealing components, mounting and specified tightening requirements before assembly.
Commissioning should check manual operation, non-return function and connection leakage. Use the applicable test procedure and acceptance criteria. Do not treat the dust cap as a pressure seal.
Inspection records should identify the supplied valve configuration. Where required, request dimensional, pressure and leakage-test documentation with the relevant test conditions and results.
Routine maintenance includes the interface, handle, cap and connections. Read our gas conversion system maintenance guide for related information.
Request a Valve Configuration and Quotation
