Real time quotation for ReXROTH proportional valve from Rexroth

Real time quotation for ReXROTH proportional valve from RexrothThe command signal of the ReXROTH proportional valve from Rexroth is amplified by a proportional amplifier, and a proportional current is output to the proportional solenoid of the proportional valve. The proportional solenoid outputs force and moves the position of the valve core proportionally, which can control the flow rate and change the direction of the flow proportionally, thereby achieving position or speed control of the actuator. In some applications that require high precision in position or velocity, a closed-loop control system can also be formed by detecting the displacement or velocity of the actuator.

When the fluid cleanliness of the ReXROTH proportional valve is not high, a filter should be installed in front of the solenoid valve. Generally, solenoid valves require good cleanliness of the medium. Pay attention to the flow aperture and pipe diameter; Electromagnetic valves are generally only controlled by a switch with two positions; If conditions permit, please install a bypass pipe for easy maintenance. Pay attention to the influence of environmental temperature on solenoid valves. The power supply current and power consumption should be selected according to the output capacity. The power supply voltage is generally allowed to be around ± 10%. It is necessary to pay attention to the high VA value during AC starting.

The working principle of the ReXROTH proportional valve from Rexroth is as follows: the command signal is amplified by a proportional amplifier, and a proportional current is output to the proportional solenoid of the proportional valve. The proportional solenoid outputs force and moves the position of the valve core proportionally, which can control the flow rate and change the direction of the flow proportionally, thereby achieving position or speed control of the actuator.

Analysis of Rexroth REXROTH Proportional Valve:

Flow range: The flow range that Rexroth proportional valves can provide is one of the important parameters. It represents the minimum and maximum flow values that the valve can control.

Pressure difference: The Rexroth proportional valve will cause a certain pressure difference during operation, which is the difference between the inlet pressure and the outlet pressure. This parameter also needs to be selected according to specific application requirements.

Control accuracy: The control accuracy that Rexroth proportional valves can provide is also an important indicator. It represents the possible range of error between the actual output and the expected value of the valve when setting the flow rate or pressure.

Response time: Response time indicates the time required for a Rexroth proportional valve to receive a signal and actually output a corresponding change when the input signal changes.

Temperature range: This parameter represents the temperature range within which the Rexroth proportional valve can operate normally and maintain stable performance.

Control method: The Rexroth proportional valve can be controlled by current, voltage, or other signals. Different control methods are suitable for different application scenarios.
