Hydraulic cartridge valves also known as cartridge valve or logic cone valve by inserting components, control cover, channel block three major components, insert components are spool and sleeve, spring and seals composition; control cover plate.
Hydraulic cartridge valves according to the different control functions, equipped with the corresponding pilot control level components: channel block is embedded into the components and install the control cover basic body, is the main circuit and control circuit of the connected component.
It is a simple structure and standardized, high level of generalization through the oil capacity. Hydraulic cartridge valves fluid resistance small, with good sealing performance and dynamic characteristics of a new hydraulic control valve. Present in hydraulic presses, plastic molding machines, die-casting machines and other high-pressure high flow system is widely used.
