Product Features
TRM20E Series Hydraulic Control Flow‑Sharing Sectional Valve
·Sandwich plate design, flexible combination on demand.
·Load pressure compensation, load pressure independent flow distribution.
·Hydraulic pilot control, electric proportional (or switch) control.
·Load holding function is available for boom and arm.
·Adjustable working priority sequence of each plate .
·Limitation of system maximum pressure via LS pressure relief valve.
·Limit the load of actuator system and set secondary pressure via pressure relief valve.
·Low pressure drop and less fuel consumption.
·Precise control, stable proportional control, comfortable operation.
·High repetition accuracy, small hysteresis.
Applications
Perfect for 7‑10 ton excavators, mobile crushers, drilling rigs, truck‑mounted cranes and other heavy‑duty construction machinery. Well‑suited for mobile hydraulic equipment that needs high‑performance flow sharing sectional valves for complex multi‑action hydraulic operations.
