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.

Media Compatibility
These valves are suitable for air, water, and light oil, with a maximum differential pressure of 1 to 200 bar. The maximum media temperature is 100°C, and the ambient temperature range is -10°C to +50°C. The maximum viscosity for media is 40 centistokes.

Installation and Operation
The valves should be mounted vertically with the coil facing upwards. The weight is 570 g for NC and 900 g for NO configurations. The opening or closing time is a maximum of 100 milliseconds.

Pressure and Seals
The valves are available with different seal materials, including NBR, EPDM, and FKM, with PTFE options 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 AC voltages of 12-230V (50 or 60 Hz) and DC voltages of 12-48V. They have a power consumption of 48 VA inrush and 24 VA holding for AC, and 14 to 20 W for DC. The insulation class is F (155°C), and the enclosure is rated IP 65 with a DIN 43650 connector.

Construction
The body, tube, and internal parts are made of stainless steel, while the seals and gaskets are available in NBR, EPDM, or FKM. The coil is moulded in resin.

Options and Accessories
Available options include a PG9 connector, NPT thread, PTFE seals, and an explosion-proof enclosure compliant with ATEX standards. Repair kits are available, including coils and complete plunger assemblies with O-rings and pistons.
