Technical Specifications
The coaxial solenoid valve 3/2, types 300400 to 300420, is designed for use with air, water, oil, and vacuum. It operates within a pressure range of 0 to 40 bar and can handle media temperatures from -20°C to +100°C. The ambient temperature range is -30°C to +60°C, and the maximum media viscosity is 500 centistokes. The valve can be mounted in any position, with an opening or closing time of 25 to 130 milliseconds.

Pressure Specifications
The valve is available in various port sizes ranging from 1/4 BSP to 1 1/2 BSP, with corresponding flow coefficients (Kv) and maximum fluid temperatures of 100°C. The materials used include brass, stainless steel 303, and stainless steel 316L.

Electrical Data
The valve operates at 230/50Hz with a connector that includes a rectifier, or at 24V DC. Power consumption varies from 35W to 58W depending on the model. It features an insulation class F (155°C) and an IP65 enclosure rating, with electrical connections conforming to DIN standards.

Overall Dimensions
The dimensions and weights vary by model, with lengths ranging from 170mm to 249mm and weights from 1.7kg to 7kg.

Construction
The valve body is made from brass for the 300400 version, stainless steel 303 for the 300410 version, and stainless steel 316L for the 300420 version. The tube and internal parts are stainless steel, with FKM seals.

Options
Available options include a normally open (NO) version, PTFE seals, a high-temperature version up to +180°C, fastening brackets, and PN40 flanges.
