he code you provided, R900778463, identifies a Directional Control Valve with an H-4WEH16G7X/6EG24N9K4/B10P4,5D3 body style from Rexroth. This particular valve is designed for use in industrial automation systems where precise control of fluids is required. Here's a breakdown of what each part of the code means:
R9: The first three digits represent the product family code for directional control valves from Rexroth.
00: The next three digits indicate the nominal width of the valve.
77: The following two digits denote the length group code for the specified valve. In this case, it represents a standard intermediate size.
G7: The last three digits signify the configuration (specification level) of the valve. Here, G7 stands for "normal version." Other options include G8 (high pressure), G9 (heavy duty), etc.
X: This letter indicates that the valve has been optimized for direct mounting on a plate or manifold.
EG24N9K4: The preceding four letters refer to the connector system of the valve. EGs, the different connectors available for these valves include EA (threaded), EB (single ear flange), EC (double ear flange), ED (DIN en369 male thread), EE (SAE J514 female thread), ET (steam turbine drive), EU (pressure connection parallel to DIN EN299), and others. Here, we have a Euroflange (EF) connector.
B10P4,5D3: The final sequence represents various additional features and modifications applied to the basic valve body. The codes and their meanings are as follows:
B10: Position indicator (spool position feed back)
P4: Pressure relief valve (built-in load balancing piston)
5: Anti-hypertension protection (integrated safety valve)
D3: Dual solenoid actuation (electrical fail-safe mechanism)
Overall, the R900778463 Code serves as a unique identifier for a specific configuration of the Rexroth 4WEH series directional control valve. It includes information about the valve’s dimensions, configuration, and additional features, making it easy to specify precisely what is needed for any given application.
