Spring leaves - Import export

• Seat principle, direct actuated; • Frictionless movement Spider µProp-valves are real proportional valves, in which the armature stroke is proportionally defined by the infinitely-variable current applied. The constant ratio between armature stroke and flow rate thus allows variation of the flow rate by way of the applied current. Spider µProp-valves are like Spider on/off valves microvalves The anchors installed in the micro valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. These valves have a capacity of up to 4 billion actuations, depending upon operation mode.

• Sizes: Ø 7 mm, Ø 15 mm, Ø 21 mm; • Application: Neutral and mildly aggressive liquids, gases and vapors; • direct actuated; • 2-way valves and 3-way valves, NC; Spider valves are allocated to the micro valve category (outside diameter 7 mm). The anchors installed in the micronized valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. As these valves predominantly featuring cartridge connections have an almost frictionless armature movement, they have a capacity of up to 4 billion actuations, depending upon operation mode. Spider valves may also be triggered via so-called pulse width modulation.
