2ASL5LB-1-012 is an elec-hydraulic proportional directional control valve used to drive the equipment in different directions. Through adjusting the opening of the spool, the pump pressure and directional valve output can be adjusted to achieve the purpose of controlling the size and speed of the driven load.

It is applicable to all kinds of working machines and various mechanical transmission devices, which are widely used in petrochemical, light industry, metallurgy, crane, construction machinery, energy and other industries.

The main structure of the 2ASL5LB-1-012 is composed of valve body, spool, sleeve, nut and other parts. The sleeve is fixed on the valve body by the nut, and the piston is connected to the spool through the connecting rod. Under the action of the cylinder thrust, the spool movement is connected with the piston, and the spool is pushed or pulled in the lower or upper inner cavity of the valve body.

The operation of the 2ASL5LB-1-012 depends on the relative position between the spool and the sleeve. When the spool moves left or right, the cross-sectional area of the left or right chamber increases, and the oil pressure decreases on this side; then the pressure on that side increases, and the spool tends to move away from the side. By controlling the size of the pressure change on both sides of the spool, the speed and size of the electric-hydraulic proportional valve are controlled.

In terms of performance, the biggest advantage of 2ASL5LB-1-012 is its good dynamic response, high accuracy and fast response speed. Monocolor display can be used to adjust the current, velocity feedback signal can be used to adjust the velocity, and trajectory tracking can also be used to adjust the position. It can be used to drive various mechanical transmission devices (butterfly valve, solenoid valve, ball valve, cylinder, motor, etc.) for high-speed and high-precision control.

2ASL5LB-1-012 is a kind of widely used directional control valve. It is an electric-hydraulic proportional valve connected in series with two actuated hydraulic equipment in the system. It is equipped with pressure regulating device at its inlet and outlet, and can be used to control the size and speed of a hydraulic system by controlling the pressure of a hydraulic system.
