The HF02-LG
series from Rexroth rounds out its standardized range of HF valve manifold
systems with a weight-optimized base plate valve featuring high flow rates. The
HF family is now available with flow rates of 0.4, 0.7 and 1.4Cv and
can be actuated with just one bus connection for all series.
The uniform connection
technology for Rexroth valve manifold systems simplifies integration of
pneumatics in a wide variety of automation concepts. The system enables use of
multiple plugs and connections for all common field buses, with and without I/O
signal processing and supports an integrated Drive & Diagnostic Link. The
uniform interface for common field bus control (B-design) permits a simple and
clear combination of various valve manifold systems, as well as standardized
programming.
The new HF02-LG valve manifold
system benefits from a free selection of connection technology. With a flow
rate of 0.4C
v with a valve width of 20 mm, the system can
accommodate up to 16 valve positions in one unit. The modular design makes it
possible to change the electrical controller without having to disassemble the
valve manifolds. Electrical linking with other valve manifold systems, such as
the HF03-LG and the HF04-XF, or individual valves, is simple using Rexroth's
module extension.
The HF02-LG provides all valve functions: 2 x 3/2, 5/2 and 5/3. Dual-pressure
operation is possible using separate exhaust connections for channels 3 and 5.
Pressure zones can be limited to one valve. In principle, the valve manifold system
has been designed for an internal working pressure of 36 to 145 psi and can be
operated in a temperature range of 32 to 122F. Up to 32 coils can be actuated
with the 44-pin D-Sub high-density plug.
