DHZO-AEB-NP Series Proportional Directional Valve

Nowadays, the DHZO-AEB-NP series proportional directional throttle valve has been widely used in the field of industrial automation. This valve not only has the function of controlling direction, but also can realize flow control. The use of proportional solenoids allows the displacement stroke of the valve core to change continuously or proportionally, thereby realizing continuous or proportional changes in the flow area between the connecting oil ports, and realizing precise control of the movement direction and speed of the actuator.
The working principle of this valve is relatively simple. When powered on, the electromagnetic force opens the pilot hole, causing the pressure in the upper chamber to drop rapidly, forming a pressure difference of low top and high bottom around the closing part, and the fluid pressure pushes the closing part to move upward and open the valve. When the power is off, the spring force closes the pilot hole, and the inlet pressure quickly enters the chamber through the bypass hole, forming a pressure difference of low bottom and high top, and the fluid pressure pushes the closing part to move downward and close the valve.
The characteristic of this proportional valve is that the upper limit of the fluid pressure range is relatively high, and it can be installed arbitrarily (customization is required), but the fluid pressure difference conditions must be met. This also means that it can be used in some relatively harsh industrial environments and withstand high pressure difference working occasions.
At present, DHZO-AEB-NP series proportional directional throttle valves have been widely used in pneumatic servo systems, flow control systems, hydraulic punch systems, etc., bringing more stable and accurate control effects to the field of industrial automatic control. In the future development of industrial automation, this product will continue to play an irreplaceable and important role and promote the development of industrial automation technology.
