Automatic Gas Flow Regulator Valve for ATEX-Approved CNG Dispenser

Product Description

ATEX-Approved CNG Dispenser Solenoid Valves

 

Product Description

A CNG (Compressed Natural Gas) dispenser solenoid valve is a key safety and control component used in CNG refueling systems to regulate high-pressure gas flow during vehicle fueling operations. It ensures precise, reliable, and safe on/off control of gas delivery in demanding dispensing environments.

The ATEX-certified CNG dispenser solenoid valve is designed for use in hazardous areas where explosive gas atmospheres may be present. Built with robust materials, high-integrity sealing systems, and compliance with international safety standards, it delivers stable performance under high pressure and ensures safe operation of CNG fueling stations. It is widely used in both new CNG station installations and system upgrades where safety, durability, and operational reliability are critical.

CNG Gas Dispenser Components and Working Principle

A typical CNG gas dispenser consists of several key components, including a CNG mass flow meter, breakaway valve, solenoid valve, and check valve. Among these, the CNG mass flow meter plays a central role in accurate fuel measurement and directly influences overall dispenser performance and billing accuracy.

The solenoid valve (explosion-proof high-pressure control valve) is installed in the high-pressure gas line and functions as an electrically actuated shut-off element. When energized, the solenoid coil generates a magnetic field that drives the valve core to open or close the flow passage, enabling precise automatic control of gas flow. This mechanism supports fully automated fueling operations, improves safety, and enhances the efficiency and reliability of the CNG dispensing process.

Product Parameters

• The solenoid valve provides automatic, precise, and highly reliable control of the CNG fueling process, ensuring stable system operation.

• It is engineered to perform consistently under complex operating conditions, including environments with elevated oil and water content, maintaining long-term stability and durability.

• Flow control: It regulates CNG flow during dispensing by rapidly opening and closing the valve in response to system demand.

• Safety function: It is designed to minimize leakage risk and ensure secure operation under high-pressure conditions typical of CNG systems.

• Automation capability: It operates via electrical control signals, enabling fully automated opening and closing without manual intervention.
