Burkert 2 Port Normally Closed Brass Body Solenoid Valve 230V AC 16 bar 25mm Orifice Diameter 221858

Burkert 221858 is a high-quality 2 port, normally closed solenoid valve featuring a brass body and designed to operate at 230V AC supply voltage. It supports a maximum operating pressure of 16 bar with an orifice diameter of 25mm, making it suitable for controlling fluids like compressed air and water in industrial applications.

The valve series 6281 EV Standard offers servo assist for faster response with maximum opening and closing times of 4 seconds each. It provides an IP65 rating with cable protection for durability in harsh environments. The robust brass construction ensures excellent strength and long service life.

This solenoid valve is compliant with multiple standards such as ATEX, DIN EN 175301-803 Form A, and DIN EN 50930-6, along with drinking water approval KTW W270 for EPDM seals. Its design ensures quiet operation and eliminates water hammer effects commonly encountered in fluid power systems.

Compact installation length with NPT / Rc connection ports assures compatibility with existing pipeline setups. Typical applications include heating and refrigeration circuits, water treatment plants, compressed air control, and vacuum systems across various industrial and manufacturing environments.

The valve operation is characterized by a normally closed default position, meaning the valve remains closed without coil energization and opens when powered. The schematic orientation places the coil energized function on the left and spring or servo return on the right side for easy identification.

Robust brass body suitable for neutral fluids including compressed air and water. ATEX certified for hazardous area use ensuring safety in explosive atmospheres. Response times as low as 0.1 to 4 seconds depending on operating pressure conditions.

Temperature operating range from -10°C to 80°C accommodates diverse environmental conditions. Flow factor Kv of 12 m³/h supports efficient fluid throughput. Quiet and water hammer free valve design extends system and component life.

Compact design allows for easy installation where space is limited. IP65 protection rating provides resistance against dust and low-pressure water jets.

This Burkert Solenoid Valve is manufactured in Germany, reflecting high quality and engineering precision. It is ideal for industrial, HVAC, water treatment, manufacturing, and laboratory applications requiring reliable solenoid actuation for fluid control.
