Advantages:
- Process reliability in installation
- Save time setting up
- Expander types in different materials
- Available for the widest possible range of applications
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.
SEALING TECHNOLOGY
MB SERIES
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).
CV series
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
LK SERIES
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.
SK series
Pressure to 500 bar
The 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.
Installation equipment
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.
LP series
Pressure to 60 bar
The press fit and anchoring concept of the LP series makes use of a conical press-in sleeve. During installation, this adapts to the bore, and the outer serration bites into the bore wall. Particularly suitable for lower pressures (max 60 bar).
RESTRICTORS
RE series
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.
RT series
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.
KOENIG-EXPANDER®
The SFC KOENIG CHECK VALVE is an easily-installed and reliable solution for controlling the direction of flow in liquid systems.
