Operating principle
This valve combines an adjustable needle restrictor and a check valve in one unit. In one direction, the flow is reduced by the needle, allowing precise control, useful for smoothly lowering cylinders or slowing down motion.
In the opposite direction, the check valve opens fully, enabling unrestricted flow and rapid movement, such as fast lifting. This dual function ensures both efficiency and safety in hydraulic operations where directional control and speed management are essential.
