Burkert 2 Port Normally Closed Brass Solenoid Valve 230V AC 25mm Orifice Diameter Series 221 221728

Burkert 221728 is a 2 port normally closed solenoid valve manufactured from brass, designed for use with water, inert liquids, and gases. This valve operates with a 230V AC supply voltage and features a 25mm orifice diameter, making it suitable for various industrial fluid control tasks.

The valve’s maximum operating pressure is 10 bar, with an operational temperature range from -10°C to 80°C. Its servo assist mechanism enhances smooth operation and reduces water hammer effects, producing quiet performance. The IP65 rating ensures robust protection against dust and water ingress, allowing it to operate reliably in harsh environments.

This valve holds explosion protection certification Ex-i for intrinsically safe use in hazardous areas, making it compliant with strict safety standards. The high Kv flow factor of 11 m³/h supports efficient and high-volume fluid flow where required.

The compact construction facilitates easy installation in confined spaces, suited for applications such as compressed air and vacuum systems, heating and refrigeration, water treatment, and swimming pool systems. It features a minimal pressure differential for full opening and a fast response time of 0.1 to 4 seconds, enabling quick valve actuation.

Designed with precise engineering, the valve includes a soft mechanical coupling between the piston and pilot armature for enhanced operational smoothness. The valve body is optimized to minimize noise and vibration during operation.

Notes: This valve requires clean neutral media due to internal construction complexity. Electrical connectors are available separately. Manufactured from durable brass material for liquid and inert gas handling. Normally closed valve design suitable for precision fluid control.

Operates at a maximum pressure of 10 bar with temperature range -10°C to 80°C. Features servo assist mechanism ensuring smooth and quiet operation. IP65 rated for protection against dust and water ingress. Certified for explosion protection Ex-i (intrinsically safe) hazardous areas.

High flow capacity with Kv factor of 11 m³/h for efficient fluid passage. Compact design allows installation in limited space environments. Ideal for applications including compressed air, vacuum systems, heating, refrigeration, and water treatment.

Engineered to open without differential pressure with a fast response time between 0.1 to 4 seconds. Explore more Burkert Solenoid Valves and industrial fluid control solutions at EnvMart to find the optimal valve configuration for your application requirements.
