Tried and tested valve design nears 50 years of reliable service
As a design concept, the pivoted armature solenoid valve has certainly withstood the test of time. Originally designed by Christian Bürkert nearly 50 years ago, this extremely reliable and versatile valve design continues to be a best seller for Bürkert Fluid Control Systems.
Available with a wide range of options to suit an array of applications, the pivoted armature solenoid valve provides a cost effective, reliable process control solution.
Compared to the plunger-type versions, pivoted armature valves from Bürkert have all three port connections integrated in the body of the valve, which places them all in the same plane, making connection design easier. The valves are equipped with a lockable manual override as standard and have the option of a visual position indicator or an electrical feedback.
Available in 2/2 or 3/2 way configuration, the design uses an isolating diaphragm, which ensures that no fluid is allowed to enter the armature chamber. This innovative solution makes the pivoted armature valve more resistant to contamination than the plunger-type valve as well as offering a higher resistance against aggressive fluids and providing a longer service life, even in non-lube conditions.
All of the materials used in the construction of Bürkert valves are carefully selected to suit a variety of applications. Body and seal materials are chosen to optimize functional reliability, fluid compatibility, service life and cost. Additional options are available with regard to material specification depending of the application and can be discussed with the engineers at Bürkert.
The valve can also be customised to suit a wide variety of specialist applications, such as the Analysis version, which is particularly suitable for switching extremely pure gaseous and liquid media. All contaminated parts are subjected to additional purification processes, so that the media is not contaminated under any circumstances. The assembly of this valve takes place under cleanroom conditions to ensure the design is not compromised.
Further versions are available with specifications such as the vacuum version, ATEX and non-standard supply voltages, all of which can be configured with different seal materials, and arranged in a multitude of circuit functions. Further information can be found here.
