The Type 6211 is a servo-assisted normally closed 2/2-way solenoid valve with a

servo diaphragm for use especially with neutral fluids and gaseous media. The

range of housing includes brass, stainless steel and plastic. The valve has a low

power consumption, low weight and a compact body. The valve is normally closed

by spring force. Energized, the solenoid opens the pilot valve first. Then the medium

pressure opens the main valve due to the pressure drop above the diaphragm. The

valve opens. The special design and geometry of the inner parts of the valve result

in a soft closing function and cause almost no water hammer.
