Bosch Rexroth UPE2-1X/2, 2R2, 55/5AT-B0V Part No. R904101197 Clamping and Drive Module Distribution

R904101197 Bosch Rexroth UPE2 clamping and drive module (51142) uses the IH15A control module to implement complete hydraulic control. They can be equipped and assembled individually. Directional valve modules and seat valve modules can be combined with each other, and the control module can be directly connected to the clamping and drive module UPE2. However, with the help of external accessory modules, the hydraulic control unit can also be installed in any system. The RBAIH15A type reduction module enables the IH15A module to be directly mounted on the container cover of traditional drive units. Using the RIH15AR type pressure reducing module, the hydraulic control unit can be connected to the control devices of the IH15B control module series. This module is preferably designed for hydraulic control units of small volume consumers with a volumetric flow rate not exceeding 379 l/min. They are interconnected by two tie rods.

R904101197 Overview of Accessory Modules for Clamping and Drive Modules

1) Basic module "G": – Basic module with integrated relief valve for simple lowering and holding functions. – If the basic module "G" is used, further stacking is not feasible. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH15A". 2) Directional valve module "W" 1): – Design allowing control using valves with porting surfaces conforming to DIN 24340 form A. – The number of directional valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH15A". 3) Seat valve module "S" 1): – The basic composition of the seat valve includes: • One relief valve block. • One or several control blocks. • One end block. – Control is designed according to the specific application. – The number of seat valve modules depends on the discharge volume and pump displacement. – For more details, see catalog "Control Block Types for Clamping and Drive Modules IH81A". Directional valve modules and seat valve modules can be combined!

R904101197 Air Breathers and Oil Pans for Clamping and Drive Modules

Air breather (option): We recommend using an air breather when operating clamping and drive modules in heavily contaminated environments. During installation, the connection between the air breather and the engine intake pipe, whether via flange, rubber hose, or direct connection, must be tight and reliable to prevent air leaks. Rubber gaskets must be installed on both ends of the filter element. The wing nuts securing the air breather housing must not be overtightened to avoid crushing the paper filter element. During use, protect the paper core air breather from rain, as absorbing large amounts of moisture will significantly increase intake resistance and shorten service life. Additionally, the paper core air breather must not come into contact with oil or fire. Oil pan (option) (dimensions in mm): Size 3 and Size 4 Material No. R901109231, Size 5 and Size 7 Material No. R901109235, Color: RAL 7101 "Light Gray".
