Pivoted armature valve 330

More than 45 years ago the pivoted armature technology opened a new chapter in valve automation. It was Christian Burkert himself who initiated this pioneering valve technology. Today this unique valve innovation is used in virtually all industries. The pivoted armature can be found in the chemical processing industry, in pharmaceutical and medical technology and in the pilot control valves of fire extinguishing systems and sewage treatment plants. Decades of application experience and continuous orientation to the (application) requirements of our customers make it one of the most...

Diameters: Body material: Process connections: Pressure range: Media temperatures: Viscosity: Seal material: Burkert developed the pivoted armature valve back in the sixties. It incorporates unparalleled expertise gained over a period of decades. Numerous possibilities for combining the product components made the pivoted armature valve a surprisingly versatile classic valve. It can be used as a direct-acting 2/2- and 3/2-way solenoid valve, but is also ideal as a pilot valve for servo applications. Due to the encapsulation of the coil and mechanical parts, the pivoted armature valve is...

Diverse process connections Body materials for all applications Process connection types that reduce costs Metal connections The brass fluid body is used primarily in chemically non-critical media, such as oils or water. Plastic connections The fluid bodies, made of plastics such as polypropylene (PP) or PVDF are highly resistant to media. Particle-bearing media also have no effect on the reliable switching of the valve. These versions are suitable especially for applications involving acids, alkalis or chlorine, as well as metal-free applications in the pharmaceutical and semiconductor...

Coil technology to save energy Separating membranes for optimal protection Other voltages available on request Encapsulation Encapsulation of the actuator from the fluidics by a separating membrane allows use of the valve in aggressive and / or contaminated media. This provides a reliable solution for controlling highly sensitive liquids in medical and pharmaceutical engineering applications requiring against contamination from outside. Analysis and filter systems are examples of such applications. Membrane material and seals Different sealing materials, such as NBR, FKM or FFKM, are...

The product spectrum at a glance Explanation of operating principles The above information provides an extensive overview of the properties and functions of the pivoted armature valve. On the following pages you can learn more about the technical details and options, to help you choose the right product for your requirements. 2/2-way valve, normally closed 2 (A) Bürkert operating principle A In de-energised state the pivoted armature presses the valve seal onto the valve seat by spring force, closing the valve. Under voltage, the pivoted armature is attracted by magnetic force to the coil...
