Control Valve Excavator PC200-8 Komatsu
Fungsi Control Valve Excavator PC200-8
Control valve excavator pc200-8 terdiri dari valve 6-spooln ( satu komposisi tubuh) dan satu set layanankatup. Katup pembagi gabungan, tekanan punggung katup dan pencegahan drift hidrolik boom katup dipasang untuk itu.
Karena semua control valvedirakit bersama dengan menghubungkan baut dan pass mereka terhubung satu sama lain di dalam housing, Perakitannya kompak dan mudah dirawat. Dengan satu spool disediakan untuk satu peralatan kerja, Kontrol valve excavator PC200-8 Komatsu ini sederhana dalam konstruksi
