Refueling Interface and Outlet Connection Selection
This CNG filling valve is listed with a nominal pressure of 20MPa, a DN4mm passage and a net weight of 273g. It is offered for compatible natural gas vehicle refueling installations. Match the exact interface, pressure designation and outlet connection before ordering.
The NGV1 product designation does not replace a dimensional compatibility check. Provide the mating nozzle specification and the valve drawing when selecting the connection. Do not assume that every CNG refueling nozzle will fit.
Main Technical Parameters
| Item | Specification |
|---|---|
| Product type | CNG filling valve |
| Product designation | NGV1; confirm the exact interface specification for the supplied version |
| Nominal pressure PN | 20MPa |
| Nominal diameter DN | 4mm |
| Outlet connection description | Ferrule Type Hole 6; confirm tube size, thread and sealing details from the drawing |
| Quick coupling | Confirm the mating profile, pressure designation and applicable interface documentation |
| Integrated temperature-pressure safety device | Not fitted |
| Net weight | 273g |
What Must Match Before Installation?
Both the refueling interface and the outlet connection require verification. A matching nominal pressure alone does not establish mechanical or sealing compatibility.
Refueling interface: Confirm the mating nozzle profile, connection dimensions and pressure designation.
Outlet fitting: Identify the tube dimensions, thread details and specified sealing arrangement.
Mounting: Check installation dimensions, support requirements and access for connection.
Operating conditions: Confirm the permitted temperature range and service conditions for the supplied version.
Documentation: Request the model drawing, installation instructions and applicable inspection or approval records.
Standard conformity must be supported by documentation for the exact product. Confirm the standard number, edition and scope before specifying a compliance requirement. A general NGV1 label or quick-coupling description is insufficient on its own.

Frequently Asked Questions
Which vehicles can use this filling valve?
Compatibility depends on the vehicle's CNG refueling system. Check the mating interface, pressure specification, outlet fitting and mounting arrangement. Vehicle category alone does not identify the correct valve.
What does the 20MPa value represent?
20MPa is the nominal pressure supplied for this product. Confirm the permitted operating conditions against the markings and technical documents. Do not treat this value as a proof-test or burst-pressure rating.
Does the valve include a temperature-pressure safety device?
No integrated temperature-pressure safety device is specified for this model. Confirm the complete system's protection arrangement separately. This statement does not identify whether other valve functions, such as a check valve, are present.
Does “Ferrule Type Hole 6” mean a 6mm tube connection?
The connection dimensions must be verified from the drawing. This description alone does not fully define the tube diameter, thread or sealing geometry. Send the mating fitting details before ordering.
Can it connect to any NGV1 nozzle?
The exact mating interface and pressure designation must match. Confirm compatibility using the nozzle and valve documentation. See our NGV refueling interface comparison for related selection information.
Installation and Inspection
Installation must follow the instructions for the selected valve and CNG system. A qualified technician should verify the connection specification, sealing components, mounting and tightening requirements.
Commissioning requires the specified functional and leak checks. Verify the functions documented for the supplied model. Do not infer automatic shutoff or check-valve performance from the product name.
Inspection should cover the filling interface, mounting and connected line. Follow the equipment maintenance schedule and replace damaged or defective components according to the service instructions. Read our gas conversion system maintenance guide for related information.
Request Interface Details and a Quotation
Send the mating connection details with your inquiry. Include nozzle identification, outlet fitting dimensions, installation photographs, destination country and quantity. Browse our autogas spare parts, or contact us to confirm the filling valve version and documentation.
