Product Overview of High-Pressure CNG Solenoid Valves

High-Pressure CNG (Compressed Natural Gas) Solenoid Valves adopt a piston-type internal structure, featuring stable performance and excellent sealing. They are mainly used for automatic control of pipelines carrying medium and high-pressure natural gas, high-pressure gases, heat transfer oil, and other media. Widely applied in fields such as military industry, aerospace, marine heavy industry, nuclear industry, petrochemicals, electric power, chemical industry, light industry, machinery, scientific research, drying equipment, food processing, medical equipment, cleaning equipment, and automatic control of steam pipelines.

Key Features of High-Pressure CNG Solenoid Valves

Corrosion Resistance: Core components (valve plug, valve body, etc.) are made of stainless steel 304 and 316, ensuring superior corrosion resistance.

Wear Resistance: Rational material selection; the valve plug and valve body cleverly utilize fluid lubrication to reduce wear, significantly extending service life.

High Pressure Resistance: Adopts a pilot piston-type structure, realizing reliable operation under high pressure and easy opening under low pressure through advanced working principles.
