Gas and diesel solenoid valves are designed for automatic control of fluid flow in industrial burners, heating systems, and fuel distribution units. These valves typically operate at a working pressure range of 0.5 to 6 bar, depending on the model and application. Valve bodies are commonly made from brass, aluminum, or stainless steel to ensure corrosion resistance. Nominal orifice diameters vary between 10 mm and 50 mm, providing adequate flow rates. Most models comply with EN 161 and ATEX standards to guarantee safety in explosive environments. Electrical coils generally operate at 230V AC or 24V DC, with power consumption ranging from 6 to 20 watts. Response times are usually under 1 second for rapid action in emergency conditions.
Gas and diesel solenoid valves come in normally closed NC and normally open NO configurations. Seal materials such as NBR, FKM, or PTFE are chosen based on fluid compatibility and operating temperature. Operating temperature ranges from -15°C to +80°C, with some industrial models tolerating up to +120°C. Flow coefficients Kv range from 1.5 to 25 m³/h, suitable for both low and high flow systems. Threaded connections are typically BSP or NPT, available in sizes from 1/4 inch to 2 inches. Some models include features like manual reset, status indicators, or built-in filters. These valves are essential components for safety and reliable operation in fuel systems.
