HFV（液壓反饋 Valvistor )系列蓋板插裝
閥靠一個電流控制 PWM 信號利用自調(diào)節(jié)
液壓設(shè)計來控制流量，該設(shè)計實(shí)現(xiàn)對主閥
芯的伺服型控制而不用電反饋傳感器。
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.

打開先導(dǎo)節(jié)流閥（圖 2）降低容腔(3)中的
壓力，使主閥芯離開其閥座運(yùn)動。
主閥芯向上運(yùn)動直到窄槽和先導(dǎo)閥壓降影
響閥芯上的力平衡，這時閥芯處于穩(wěn)態(tài)工
況，穿過窄槽和先導(dǎo)閥的流量相等。
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.
這種閥的結(jié)構(gòu)和特征開辟了液壓缸和馬達(dá)
的廣泛的應(yīng)用領(lǐng)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)
這使窄槽掠過節(jié)流棱邊(7)，打開可變阻尼口并使流量經(jīng)過控制回路。
初，經(jīng)過先導(dǎo)閥的流量等于經(jīng)過窄槽的流量加上由于主閥芯開啟運(yùn)動而排出的流量。
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.
