Burkert 221633 Solenoid Valve is a high-quality 2 port, normally closed (NC) valve engineered for fluid handling in industrial and laboratory environments. It features a brass body and offers an inlet port size range from DN 10 to 65 mm, with a 230V AC supply voltage. The valve delivers a maximum operating pressure of 10 bar, and can operate reliably between temperatures of -10°C and 80°C. Ideal for use with clean, neutral media such as water, inert liquids, and gases, it is designed to ensure quiet, water hammer-free operation thanks to a soft mechanical coupling between the piston and pilot armature.
This valve integrates a servo assist mechanism to aid valve operation without differential pressure. Its flow-optimized housing and diaphragm geometry provide a flow factor (Kv) of 8.3 m³/h and a 20 mm orifice diameter, allowing for efficient fluid throughput. The sealed coil design makes it suitable for various industrial applications including compressed air, vacuum systems, heating, refrigeration, and water treatment.
The valve meets IP65 standards for ingress protection and carries certifications for explosion protection, being intrinsically safe (Ex-i). Its compact size supports easy installation in limited spaces in pipelines and fluid systems.
Maximum working pressure: 10 bar. Operating temperature range: -10°C to 80°C. Orifice diameter: 20 mm. Flow factor Kv: 8.3 m³/h. Body material: Brass. Servo assist available. IP65 ingress protection rating. Explosion protection certification for intrinsic safety (Ex-i).
Manufactured in Germany, this valve is suited to demanding industrial applications requiring durable and reliable fluid control components. It is part of Burkert’s 221 series solenoid valves, known for precision engineering and quality construction.
