The types of hydraulic cartridge valves can be classified from different angles. In order to classify more simply and intuitively, AAK HYDRAULIC VALVE describes the types of hydraulic cartridge valves from the most extensive installation point of view. In this way, we can divide the hydraulic cartridge valves into 3 types: Insert-type, Slide-in and Screw-in.

Berge is an old British hydraulic valve customer. The question about the type of hydraulic cartridge valve made him very nervous and helpless.

Indeed, there are many types of hydraulic cartridge valves now, from the perspective of function, hole type and scene. Here, I'll also share with you the types of hydraulic cartridge valves I gave him.

Common types of hydraulic cartridge valves are as follows:

The Insert-type hydraulic cartridge valves: completely enters the inside of the valve block and does not expose any part outside the valve block. It is positioned by its own thread or other components such as pipe joint, snap ring, retaining ring etc. For example, hydraulic check valve and two-way hydraulic flow regulating valve have this design.

The slide-in hydraulic cartridge valves: it does not have installation threads itself, and the valve spool needs to be used together with the cover plate. The valve spool is integrated in the valve block to switch the oil circuit on and off through pressure and spring force. Different cover plates are used to realize direction control, pressure control and flow control.

Screw-in hydraulic cartridge valves, that is, hydraulic threaded cartridge valves, have different brands and different hole types, which are usually unable to be interchanged in installation. At present, there are 3 commonly used pass types: ISO7789, SAE and SUN.
