HFV（液压反馈 Valvistor )系列盖板插装
阀靠一个电流控制 PWM 信号利用自调节
液压设计来控制流量，该设计实现对主阀
芯的伺服型控制而不用电反馈传感器。
The structure and characteristics of this valve opens up the hydraulic cylinder and the motor
Of the wide range of applications. These applications include die casting,
Deep drawing press, injection molding machine, container handling, chain bucket
Loaders, forestry machinery and dump trucks.
Insert the ISO 7368 (DIN 24342) already identified
Valve added HFV valve, Vickers further improved
Has a very rich product line.

打开先导节流阀（图 2）降低容腔(3)中的
压力，使主阀芯离开其阀座运动。
主阀芯向上运动直到窄槽和先导阀压降影
响阀芯上的力平衡，这时阀芯处于稳态工
况，穿过窄槽和先导阀的流量相等。
HFV (hydraulic feedback Valvistor) series cover plate
The valve is controlled by a current control PWM signal using self-regulation
Hydraulic design to control the flow, the design to achieve the main valve
Core servo type control without electric feedback sensor.
这种阀的结构和特征开辟了液压缸和马达
的广泛的应用领域。

The main spool moves upward until the narrow slot and pilot valve are down
The balance of the force on the spool, then the spool in the steady state workers
Condition, through the narrow slot and the pilot valve flow equal.
Open the pilot throttle (Figure 2) to lower the cavity (3)
这使窄槽掠过节流棱边(7)，打开可变阻尼口并使流量经过控制回路。
初，经过先导阀的流量等于经过窄槽的流量加上由于主阀芯开启运动而排出的流量。
Pressure, so that the main spool away from its seat movement. This makes it narrow
Slot the throttled edge (7), open the variable damping port and make it
The flow passes through the control loop. Initially, through the pilot valve
The flow rate is equal to the flow through the narrow slot plus the main spool
Turn on the movement and discharge the traffic.
