PCG5V型的液壓控 制源可來自就近的受控液壓缸的負載壓
力或來自遙控源。在必須使用液壓缸壓 力的場合以
及穿過關閉先導閥的微小內 泄會引起不可接受的缸“竄動”量的場 合,
可換用威格士座閥式先導閥。此先
導閥可為DG3VP-3-103A型(見樣本64 2);請向您的威格士代理人征求意見。
使用執行器供應的控制壓力代替遠程外控源的電磁先導型有快的響應。
Smooth steady lowering of heavy
weights in conjunction with flow
control valves aided by use of
externally drained models.
由于壓降小,使功率損耗較小。
采用外泄型可以與流量控制閥配合使重物平穩下放。
零泄漏設計能防止執行器因單向閥泄漏而“竄動”。
采用帶釋壓閥芯的型號可以平穩地釋放所儲存的能量。
internal leakage through the closed pilot valve would
cause an unacceptable amount of cylinder “creep”,
a Vickers poppet-type pilot valve can be substituted.
省去了單獨的安裝并可包括用于就地應 急控制的手動操作。
國際標準安裝面使它可以裝在許多現有設備上。
由于功率/重量比較高,可減少安裝成本和空間。
solenoid controlled type. The remote
piloted type operates and can be used
in the same ways as the previous 4CG
models described in the Vickers
“Industrial Hydraulics Manual”. The
solenoid pilot directional control valve
option is basically the same as the
This pilot would be a model DG3VP-3-103A (see catalog 642);
ask your Vickers representative for advice. All PCG(5)V
valves are available with or without an
integral decompression feature.
