LBFD16 manual electric proportional controlled load sensing multiple directional control valves and LBFD18 electric proportional controlled load sensing multiple directional control valves are all used to control the movement speed of hydraulic actuators to meet the requirements of stepless speed change, and are not affected by load changes, so that multiple actuators can simultaneously and independently work at different speeds and pressures until the total flow of all components reach the pump flow. The valve is electro hydraulic proportional control (LBFD16 with manual control). With precise micro-motion performance, excellent electrical proportional control characteristics, high efficiency and energy saving features. Pressure: 42 MPa for LBFD16, 32 MPa for LBFD18. Maximum flow: 200 L / min for LBFD16 series, 250 L / min for LBFD18 series. It is an ideal product for localization and upgrading of construction machinery, lifting machinery, drilling rigs, petroleum machinery, etc.
