Base plate EB 80, 4-fold, full-flow ports, 8 controls, no cart. - Riegler 151686

Valve base plate for valve island EB 80, 4 positions, full-flow ports, 8 controls, without cartridges The EB 80 "bases for valves - B" are available with either 3 or 4 positions. One version features an electrical connection for a single control of each position, designed exclusively for 5/2 monostable solenoid valves, making it physically impossible to install other valve types. Another version includes two electrical connections per position and supports all valve types. The integrated electronics manage signals from both the multi-pole connector and the fieldbus, allowing the same base to be used regardless of the island's control system. The air delivery ducts (ports 2 and 4) use cartridge-style push-in fittings. These cartridges can be easily replaced by removing the clip located beneath the base, for example when changing the pipe diameter. In the 4-position base, ports 1, 3, 5, and X are designed as full-flow ports. The 3-position base can be configured with either full-flow or differently sectioned ports, enabling the creation of islands with zones operating at different pressures.

About Valve terminals

A valve terminal combines several directional valves, their electrical control and the shared air supply in one assembly. Instead of wiring and tubing every valve separately, one bus cable and one supply line run to the terminal. The valves handle flow rates of 200 to 800 Nl/min at operating pressures up to 10 bar.

What matters when choosing

• Define the function first. Options include 5/2-way monostable, 5/2-way bistable as an impulse valve, 5/3-way with closed centre, and combinations of 3/2-way NC and 3/2-way NO on one slice.
• The connection decides how much wiring is involved. Multipole suits manageable terminals with existing parallel wiring, the version with integrated Profibus DP connects to a fieldbus controller.
• Protection class follows the mounting location. IP 65 for direct mounting on the machine, IP 40 for a protected control cabinet.
• Flow rate from 200 to 800 Nl/min has to match the volume of the connected actuators and the required cycle time.
• Where pressure is controlled rather than only switched, the proportional modules cover a control range of 0.05 to 10 bar at a maximum inlet pressure of 10.5 bar.

Typical applications

• Central valve station for handling and assembly lines with many short cylinder strokes
• Decentralised control mounted on the machine module in IP 65 to shorten tubing runs and switching times
• Packaging and filling lines where grippers, slides and suction cups are coordinated over a fieldbus
• Applications with controlled pressure, for example contact forces set by the proportional modules between 0.05 and 10 bar
• Systems running vacuum and pressure on one terminal using versions with external pilot air

Housings are made from technopolymer, from painted aluminium or from a combination of both, sealed with NBR. The specified medium is filtered, unlubricated compressed air.
