General information
Function
The type IH20 control system (complete assembly) can be realized individually from different modules and additional vertical stackings. Functionality will differ according to the selected modules, valves etc.
This data sheet describes the properties of the individual modules with frame sizes A and B of the premium and standard programs which are primarily designed for direct operated or for internally pilot-operated directional valves.
Other functions (modules) in these frame sizes and modules for larger nominal volume flows (frame sizes C and D) are available on request.
The maximum volume flows possible for the individual frame sizes depend on the admissible flow velocities of the relevant application and the existing thread connections and/or connection flanges at the IH 20 modules. Actuator ports are usually located on the back.
System set-up
The type IH20 control system (complete assembly) usually consists of the following elements:
▶ Inlet segment
▶ Intermediate segment(s)
▶ Sandwich plates, valves etc.
| 1 | Inlet segment left |
| 2 | 2-way cartridge valves (logic) |
| 3 | Accumulator segment |
| 4 | Check function in P |
| 5 | Valve segment |
| 6 | Pump inlet segment |
| 7 | Inlet segment right |
| 8 | Threaded bolt |
