PRINCIPLE / HOW IT FUNCTIONS
Extremely versatile and available in a variety of materials the KOENIG-EXPANDER® permanently resists even the most extreme loads and pressures. Originally designed for use in hydraulic assemblies, it is now well established in all industries as a component in engines, gearboxes and transmissions, suspensions and braking systems, as well as in steering and fuel injection systems.
Pressure to 450 bar
Expansion and anchorage of sleeve in hole wall is achieved by pressing the ball into the sleeve. The MB series plugs are designed for use in base materials of both low to high hardness (up to 450 bar pressure).
Pressure to 450 bar
The CV Expander plugs are available in different materials and surface treatments. The CV plugs are available in metric as well as Inch sizes. Expansion and anchorage of sleeve in hole wall is achieved by pressing the ball into the sleeve.
Advantages MB/CV series:
- Operating pressures up to 450 bar / 6500 psi
- Great range supplied from ∅ 3 – 22 mm also available in inch sizes
- Corrosion-resistant version
- Available in aluminium
- Normal working tolerance 0 -+0,1 mm
- Quick and easy to install
- Purely mechanical seal due to forced interlocking
Pressure to 60 bar
The LK Series KOENIG-EXPANDERS® are ideal for lower pressures (max 60 bar) and use the tension/expansion concept. After reaching the sufficient force, the expanding element automatically breaks off at the predetermined breaking point.
Pressure to 500 barThe tension/expansion concept of the SK series causes breaking off of the expanding element after reaching the predetermined force. These are particularly suitable for use in light metals, high pressure applications (up to max 500 bar), and also for bore holes with a smoother surface finish.
For installing the SK, HK and LK series there are simple lever shears and various hydro-pneumatic hand tools available. Here too the quantity will be critical in deciding the method used.
An expansion restrictor functions according to the push-expansion method. Expansion restrictors, which inhibit flow, are available in metric and inch sizes. Expansion restrictors are used in numerous diverse applications.
The threaded Restrictors are conveniently available in various sizes. Restrictors are currently used in numerous diverse applications such as mobile fluid power, automotive, medical, agriculture, construction, marine and aerospace.
