SV98-T3003 AT303799 Construction Machinery Parts Hydraulic Pump Solenoid Valve Safety Relief Valve for E300D E360LC Excavators

Key attributes

Product advantages

• Proportional Control Technology – As a pump proportional solenoid valve, it receives variable electrical signals from the machine's ECU and continuously and proportionally adjusts hydraulic flow into the pump. This enables precise control of the pump swashplate angle, accurately regulating pump displacement, flow rate, and output power.
• Enhanced Operating Smoothness – Unlike simple on/off valves, proportional control delivers smoother, more precise machine movements, effectively reducing operational shock and improving operator experience.
• Designed for Heavy Equipment – Consists of a solenoid coil, armature/plunger, precision-machined valve body, and heavy-duty waterproof wiring connectors, it is built to withstand high vibration, pressure spikes, and extreme environmental conditions.
• Proven Quality Assurance – Each unit is factory-tested to ensure durability, compatibility, and efficiency.
