About us
For more than 100 years, the name Blasberg has been synonymous with precision and
innovation. In 1900, Wilhelm Blasberg laid the foundation for the family business. In the
1970s, Friedrich Blasberg expanded the product range. Our many years of experience in
development, design, and manufacturing ensure first-class products to the highest technical
standards.
The newly formed Blasberg GmbH, meanwhile in the fourth generation and represented
by Mr. Dipl.-Ing. Lutz Blasberg has continued this tradition since 2008. In addition to our
products in the fields of industrial hydraulics, adhesive technology, and mining, we offer
you individual design solutions. We know the needs of our customers and develop, design,
and manufacture innovative solutions tailored to specific customer requirements. The
success of this company is based on our years of experience and our corporate philosophy
to produce reliable high quality and innovative products. We develop, produce, assemble
and test our products in our factory in Germany. The catalog shows an extract of our
product portfolio.

Hydraulic control units
Pilot control units
Pilot control units are usable in all types of powered roof support. All control units are
designed and manufactured according to customer requirements. The main control units are
equipped with 3/2-way valve cartridges. These valves are available in DN 20, DN 12 and DN
10. The control units have connections for pressure and return line. The main valves are
operated through the multi-core hose.

Hydraulic control units
Multi-cores
The multi-core consists of a number of individual hoses DN3. The number of individual
functions corresponds to the individual hoses. The positioning pins prevent incorrect
assembly. The individual hoses DN3 are marked according to the function. The hoses can be
changed individually in case of damage.
Pilot compact control units
The pilot compact control unit can be used in a range of 2 to 16 functions. In this design, pilot
control unit and main control unit are firmly connected. A rotation of the multi-core by 180 °
changes the control direction from the right to the left or from the left to the right.

Spare parts for hydraulic controls
Check valves, pressure relief valves and plug-in filter
Pressure relief valves limit the pressure and protect the hydraulic system.
Check valves release flow in one direction. The flow is blocked in the opposite
direction.
Plug-in filters are used to clean the emulsion to protect the pilot valves. The
medium flows through the filter element from the outside to the inside. The filter is
used in pilot, compact and electrical controls.

Over-center valves
Over-center valve
Over-center valves are pressure valves. When the consumer is triggered, the valve quickly
opens the outlet side. No pressure intensification can occur. Then it goes over damped into
the load-dependent throttle position. Starting jumps on consumers and associated pitching of
the components moved by them are thereby largely suppressed. The starting behavior is
achieved by way of threaded throttles with bypass check valves in the internal control
channels. The effectiveness of the threaded throttles can be changes within a certain range
and adapted to local requirements.

Pressure relief valves
Pressure relief valves
Pressure relief valves limit the pressure in the working cylinder to a fixed
maximum value (set pressure). The piston of the valve remains closed
until the pressure on the piston surface exceeds the set spring force. The
outflow of the liquid takes place either into the open or into the return line.
The sealing principle of piston valve valves is the sealing of a piston by an
O-ring. The valve is also called the piston O-ring valve.

Pilot valves (DAMS® Connection compatible)
The pilot control valve is a double 3/2-way valve. The pilot control valves operate according to
the deadman principle, which means that after the lever has been released, the cylinder stops
moving. The valve operates with a negative switching overlap and is pressure-free in the non-
actuated state. During the switching process, the return is first closed; the pressure is
released and connected to the return. This is the reason why the valve is very soft. Locking
levers are mounted for functions that require permanent pressure. The connection of the pilot
control valves is compatible with Dams®.

Way valves
Replacement cartridge for pilot valves
The pilot control valve is a double 3/2-way valve. The pilot control valves operate according to
the deadman principle, which means that after the lever has been released, the cylinder stops
moving. The valve operates with a negative switching overlap and is pressure-free in the non-
actuated state. During the switching process, the return is first closed; the pressure is
released and connected to the return. This is the reason why the valve is very soft. Locking
levers are mounted for functions that require permanent pressure. The replacement cartridges
are available for the respective pilot valves.

Single prop valves
Single prop valves and cartridge
The single prop valve is used to operate and Limit pressure in single props. The pressure
relief valve integrated in the single props secures the prop against overpressure. By inserting
the key into the bore of the single ram valve, the piston valve can be actuated mechanically.
The nozzle valve is opened by the rotation of the key and the prop withdraws.

Twin check valves
The unlockable twin check valve DN10 (twin RSV) consists of two check valves cartridges.
The twin check valve is used to bring the working cylinder into a certain position by the
hydraulic pressure until the return flow of the medium is released by a control signal from the
other check valve. The unlockable twin check valve operates as follows: If the medium flows
through the one check valve, the other is relieved and the return flow can take place. (PT =
piston space, NT = annulus)
