Product Details

Burkert Solenoid Valve

The Burkert 6211 series 1/2inG female servo assisted solenoid valve has a supply voltage of 230VAC. This 2-port NC position valve with a servo diaphragm is a push-over system and has high-quality NBR seal. 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 special design and geometry of the inner parts of the valve result in a soft closing function and cause almost no water hammer. The maximum opening and closing time of the valve is 25ms and 120ms. It is suitable with gas, air, water and oils, other liquids that do not contain oils or greases, hot water up to 70°C, alkaline and bleaching detergents.
Compact solenoid valves suitable for most gas and fluid handling applications. Where practical, valves are shown with a schematic diagram showing the (circuit) function. The diagram is laid out so that the left-hand side of the diagram describes the operation of the valve when the coil is energised. When the coil is de-energised, the spring (or servo-assist) return controls the valve and is described on the right-hand side of the diagram. The 3 / 2-way designation indicates a valve with three ports and two modes of operation. It is normal practice to refer to 2 / 2-way valves as two ways. The port designations A, B, P, P1, P2 and R are used on the schematic diagrams and are marked on the valve bodies. Valve bodies are marked for a specific circuit function but can often be used for other functions. Reference to the schematic diagrams and technical specifications indicates the appropriate connections and pressure capabilities when an alternative circuit function is required.
