6211 2/2-Way Diaphragm Solenoid Valve

Brand: Burkert Fluid Control Systems
Does not ship to United States

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 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.
