Hydraulic Cartridge Valves
Hydraulic cartridge valves come in a variety of standard sizes that are designed to fit a wide range of regular valve cavities. Hydraulic cartridge valves can be easily removed and replaced without taking a machine apart. Because of their design, cartridge valves result in lower maintenance fees.

Design of Hydraulic Cartridge Valves
Like most hydraulic valves, cartridge valves are usually made from durable but corrosion resistant metal such as aluminum, stainless steel, copper, or iron. Surface treatments that can be applied to improve the already positive cartridge valve characteristics include nickel plating, chrome plating, polishing, and powder coating. The positive characteristics include durability, hardness, and precision. Careful machining also ensures that these valves are leak-free, making them vital to the company buying them since leaking means more money must be spent on repairs. They are used in CNC machining systems, roughness and hardness testers, projecting apparatuses, and various vehicles' body work. Often sold in sets with numerous sizes that fit regular industrial pipes, hydraulic cartridge valves may also be custom made. Another common hydraulic characteristic that the cartridge valves share is the variety of sizes they might come in, from a fraction of a millimeter to three or four meters long. With such a wide range of applications, the size must be flexible.
Applications of Hydraulic Cartridge Valves
Hydraulic cartridge valves are usually screwed into the cavity of the hydraulic system. Cartridge valves are available for almost every kind of hydraulic valve, including check valves, control valves, relief valves, and solenoid valves, to name a few. Hydraulic check valves are automatic mechanical devices that allow hydraulic fluid to flow in one direction and prevent flow reversal, and they are often used in conjunction with motors, pumps, and cylinders as a part of braking systems and construction tools. Hydraulic control valves, in comparison, are used to contain and transfer the flow and pressure of hydraulic fluid in hydraulic systems. Hydraulic relief valves are instead used to limit the pressure and protect hydraulic systems from exposure to pressures exceeding the specified limits and are vital to any system involving an engine, transmission, and brake systems, such as cars, airplanes, trains, and boats. Comparatively, hydraulic solenoid valves are electrically operated devices that control the flow of liquids, working by way of remote control.
