Burkert 221606 Servo-Assisted Solenoid Valve (Type 6213)
The Burkert 221606 is a 2/2-way normally closed (NC) servo-assisted diaphragm solenoid valve from the Type 6213 series (6213 EV). Built with a soft mechanical coupling between the main diaphragm and pilot armature, it allows smooth, spring-coupled operation from 0 bar differential pressure, offering quiet switching and reliable water hammer dampening in liquids and inert gases.
