The Rexroth 4WRPEH is a proportional directional valve that is used in hydraulic systems to control the direction and flow of fluid. Here are some of the key parameters and specifications for this valve:

1. Maximum flow rate: The maximum flow rate of the 4WRPEH valve is 80 liters per minute (L/min).
2. Maximum pressure: The maximum pressure rating for the valve is 350 bar.
3. Control voltage: The valve operates on a control voltage of 24 volts DC.
4. Spool type: The 4WRPEH valve uses a proportional spool to control the flow of fluid.
5. Electrical interface: The valve has an integrated digital electronics module (OBE) that is compatible with a wide range of fieldbus interfaces, including CANopen, Profibus DP, and EtherCAT.
6. Operating temperature: The valve can operate at temperatures ranging from -30°C to +60°C.
7. Mounting style: The valve can be mounted in any position, but is typically mounted on a manifold using standard DIN 24340 mounting holes.
8. Feedback signal: The valve provides a feedback signal that can be used for closed-loop control of the system.
9. Response time: The valve has a fast response time of less than 20 ms.
10. Leakage rate: The valve has a low leakage rate of less than 5 cm3/min.

The cost of a Rexroth 4WRPEH valve can vary depending on several factors, such as the specific model, configuration, and supplier. Other factors that may affect the cost of the valve include the quantity ordered, the delivery time, and any additional accessories or components that are required.
