1.Patented ServoJet jet-pipe pilot features superior contamination resistance vs nozzle-flapper pilot, stable continuous operation under moderately polluted hydraulic oil, P02 external pilot improves main valve dynamic stability under fluctuating system pressureMoog Inc..2.10% positive overlap four-way spool realizes stable pressure/force closed-loop regulation; onboard LVDT closed-loop compensates spool thermal drift, K+VSX2HA further suppress long-time zero shift under wide ambient temperature variation.3.HON spring-centered fail-safe design: spool automatically returns neutral after power failure to block A/B oil circuit and lock actuator for equipment overload protection.4.External pilot(P02) structure avoids main supply pressure fluctuation disturbing pilot control, suitable for system with unstable main oil source; F6 6-pin plug simplifies field wiring installation.

1.Mount 3μm high-pressure inline filter on main P pipeline and independent P02 pilot oil pipeline separately; replace filter element after 15 working days of commissioning.2.Separate power and shielded control cables in different wiring troughs to avoid inverter harmonic interference; install valve with specified torque and standard flat washers.3.All flow gain, null offset and amplifier parameters factory pre-calibrated; only tiny on-site potentiometer fine adjustment permitted; complete disassembly of ServoJet pilot cartridge is strictly prohibited.4.Plug unused Y/T/pilot spare ports with original factory plugs for spare storage; store in dry dustproof warehouse to prevent fluorocarbon seal ageing and leakage.
