4WRSE10V80-32  比例阀 把输入的电信号按比例转换成力或位移.

4WRSE10V80-32是一种力士乐比例阀，其主阀是靠前置级阀的输出压力来控制的，而前置级阀的压力则来自于伺服阀的入口p。如果p口的压力不足，前置级阀就不能输出足够的压力来推动主阀芯动作。

比例阀是一种把输入的电信号按比例转换成力或位移，从而对压力、流量等参数进行连续控制的一种液压阀。

4WRSE10V80-32比例阀由直流比例电磁铁与液压阀两部分组成。其液压阀部分与一般液压阀差别不大，而直流比例电磁铁和一般电磁阀所用的电磁铁不同，采用比例电磁铁可得到与给定电流成比例的位移输出和吸力输出。比例阀按其控制参量可分为比例压力阀、比例流量阀、比例方向阀三大类。

4WRSE10V80-32调节阀工作原理是通过改变阀盘的开度来调节介质的流量。当阀盘完全关闭时，介质无法通过阀门，流量为零。当阀盘完全打开时，介质可以无阻碍的通过阀门，流量最大。在阀盘从关闭到打开的过程中，阀盘的开度和流量呈线性关系。

4WRSE10V80-32调节阀的开度由执行机构控制，执行机构可以是手动操作的，也可以是电动、气动或液动的自动操作。

调节阀的优点有：

能够实现流量的调节。

适用范围广，适用于各种介质，如液体、气体、蒸汽等。

可维修性高，结构简单，易于维护和清洁，也方便更换零件。

调节阀的缺点有：

成本相对较高，主要是由于其精密的流量控制要求导致。

对流体压力要求较高，普遍对流体的入口和出口压差有要求，这可能会产生额外的装置和管道成本。

对管道的反应速度较慢，可能会导致系统的响应速度比较慢，这可能会影响工业系统的安全性和稳定性。

The 4WRSE10V80-32 is a Rexroth proportional valve, the main valve is controlled by the output pressure of the prestage valve, and the pressure of the prestage valve is from the servo valve inlet p. If the pressure at the p port is insufficient, the prestage valve cannot output enough pressure to drive the main spool action.

Proportional valve is a kind of hydraulic valve that converts the input electrical signal into force or displacement proportionally, so as to continuously control the pressure, flow and other parameters.

The 4WRSE10V80-32 proportional valve is composed of DC proportional electromagnet and hydraulic valve. The hydraulic valve part is little different from the general hydraulic valve, and the DC proportional electromagnet is different from the electromagnet used in the general solenoid valve, and the displacement output and suction output can be obtained proportional to the given current by using the proportional electromagnet. Proportional valve according to its control parameters can be divided into proportional pressure valve, proportional flow valve, proportional direction valve three categories.

The working principle of 4WRSE10V80-32 regulating valve is to adjust the flow of the medium by changing the opening of the valve disc. When the valve disc is completely closed, the medium cannot pass through the valve and the flow rate is zero. When the valve disc is fully open, the medium can pass through the valve without hindrance, and the flow rate is maximum. In the process of the valve disc from closing to opening, the opening degree of the valve disc and the flow rate are linear.

The opening of the 4WRSE10V80-32 regulating valve is controlled by the actuator, which can be manually operated or automatically operated by electric, pneumatic or hydraulic.

The advantages of regulating valve are:

Can realize the adjustment of traffic.

Wide range of application, suitable for all kinds of media, such as liquid, gas, steam, etc.

High maintainability, simple structure, easy to maintain and clean, but also easy to replace parts.

The disadvantages of regulating valve are:

The cost is relatively high, mainly due to its precise flow control requirements.

Fluid pressure requirements are high, and there are generally requirements for the inlet and outlet pressure difference of the fluid, which may incur additional installation and piping costs.

A slower response to the pipe may result in a slower response to the system, which may affect the safety and stability of the industrial system.
