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 0.4Cv 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.
