Technical Specifications
The solenoid valve models 206252 to 206259 are constructed from stainless steel 316L and are available in normally closed (NC) or normally open (NO) configurations. They are designed for pressure-assisted operation with a piston and can handle media such as air, water, and light oil. The differential pressure range is 1 to 200 bar, with a maximum media temperature of 100°C and ambient temperature range from -10°C to +50°C. The maximum viscosity for the media is 40 centistokes. The valves must be mounted vertically with the coil facing upwards. The weight varies between 570 g for NC and 900 g for NO configurations, with an opening or closing time of 100 milliseconds maximum.

Pressure and Seals
The valves are compatible with various seal materials including NBR, EPDM, and FKM, with PTFE options available for higher pressure applications. The maximum fluid temperature varies with the seal material, ranging from 60°C to 180°C.

Electrical Data
The valves operate on a range of voltages (12-230V AC or DC) with power ratings of 48 VA for AC and 14 to 20 W for DC. They are designed for continuous duty (100% duty cycle) and have an insulation class of F (155°C) with an IP65 enclosure rating. Electrical connections are made via a DIN 43650 connector.

Construction and Options
The body, tube, and internal parts are made from stainless steel, while the seals and gaskets are available in NBR, EPDM, or FKM. The coil is moulded in resin. Optional features include a PG9 connector, NPT thread, PTFE seals, and an explosion-proof enclosure compliant with ATEX standards.

Repair Kits
Repair kits are available for maintenance, including coils and complete plunger assemblies with O-rings and pistons. The kits are coded based on the valve model and seal material.
