CNG Refueling Valve | 26 MPa ISO15500 High‑Pressure CNG Fill Point for CNG Car Retrofit

We supply Auto Gas Refueling Valve, a high-pressure precision refueling control component professionally engineered for automotive CNG and LPG dual-fuel gas conversion systems. Serving as the core inlet safety part of vehicle gas fuel systems, this auto gas refueling valve undertakes critical functions including standardized gas filling, high-pressure bearing and tight pipeline sealing during refueling operations. Adopting premium high-strength brass integrated forging technology, it delivers outstanding pressure resistance, corrosion resistance and high-temperature stability, perfectly adapting to extreme high-pressure working conditions of automotive gas cylinders. Equipped with a precision one-way anti-backflow structure and multi-layer safety pressure protection design, it effectively avoids gas backflow, pipeline leakage and abnormal pressure fluctuations, ensuring safe, smooth and high-efficiency CNG/LPG refueling. Featuring a universal standard interface, strict automotive-grade manufacturing standards and ultra-high operational safety, this gas refueling valve is an essential original matching accessory for automotive fuel-to-gas modification projects and aftermarket replacement.

Product Introduction

This CNG refueling valve is for car CNG systems. It is the fill point on the vehicle. Gas goes in here from the station nozzle. The valve holds high pressure and sends gas into the CNG tank. It also stops gas from going back out.

The body is brass. It has a blue solenoid coil, a manual service knob, and standard threads. The body is marked MAX WP 26 MPa, -40°C to +120°C, and ISO15500. This valve is CNG only. Do not use it on LPG.

Old fill valves can leak, stick, or lose pressure. That makes filling slow and can be unsafe. This valve is made to fix that. It is a good replacement part for many CNG cars, taxis, vans, and fleet vehicles.

Core Product Features

High-Pressure Build: Brass body. Rated MAX WP 26 MPa. Handles tank pressure at fill time.

One-Way Flow: Gas goes in, not back out. Helps keep tank pressure stable.

Blue Solenoid Shut-Off: Cuts gas when the key is off. Confirm 12V or 24V before order.

Wide Temp Range: -40°C to +120°C. Works in cold winter and hot summer.

ISO15500 Standard: Marked on the body. Helps match common CNG kits.

Manual Service Knob: Lets techs bleed and check the line.

Leak-Tested: Each unit gets a pressure hold and leak check before packing.

Product feature and application

Core Working Advantages

This valve is built for real CNG work. The brass body is strong. It does not bend or crack under normal fill pressure. The one-way design keeps gas in the tank after fill. The solenoid shuts the line when the engine is off. The manual knob helps with service. Threads are standard. It fits many common CNG kits. It is compact, so it fits tight engine bays.

Main Application Scenarios

Use it on CNG converted cars, taxis, vans, light trucks, and fleet vehicles. It works for daily city driving and long highway runs. It is a good part for CNG shops, parts wholesalers, and fleet maintenance. It is a replacement part for a bad fill valve. CNG only. Not for LPG.
