OEM-Grade LS Signal Selector Valve for PC120-6 Excavators

This LS signal selector valve, Model YH-062, falls under Hydraulic Control Valves, specially developed for 12-ton Komatsu PC100-6, PC120-6 and PC130-6 crawler excavators equipped with HPV75 hydraulic main pump, OEM Part No.723-30-60101. Installed on the LS feedback valve seat of main control manifold, it serves as the core signal distribution component of the full-machine load sensing energy-saving hydraulic system. Matched with Hydraulic Safety Valve and Hydraulic Relief Valve, it builds double-layer pressure protection oil circuit for excavators; when cooperating with 600 Series Test & Switching Valve, it supports pressure detection and debugging of hydraulic circuit. It adopts standard LS control differential pressure of 2.0MPa, maximum system withstand pressure of 31MPa and maximum feedback flow capacity of 30L/min.   This cartridge valve integrates six core functions: maximum load signal selection, one-way pressure retention, pressure shock damping buffering, impurity pre-filt…
