Restricted Adapters are specialized adapters used in hydraulic systems that restrict fluid flow to a specific direction. They typically feature a small orifice or restrictor within the adapter to regulate fluid flow. They are commonly used in applications where excessive fluid flow can cause system damage, such as in pressure control circuits, cylinder speed control, and metering circuits.

The size of the restrictor in the adapter determines the flow rate of the fluid, and it can be customized to meet specific application requirements, such as R.000, R.016, R.024, R.031, R.040, R.055, R.062, R.082, R.094, R.095, and ect. 

One of the significant advantages of using restricted adapters is that they offer precise control over fluid flow and help prevent system damage due to excessive flow. They also help improve system efficiency and reduce the risk of hydraulic fluid leaks and spills.
