What is a hydraulic cartridge valve?

Cartridge Valves, also known as 2/2-way valves or logic elements, are industrial hydraulic valves used for directional, pressure, check, and flow control. These cartridge valves are a compact design that can be used in hydraulic manifold systems for many types of industrial and mobile machinery.

What are the different types of hydraulic valves?

From a broad perspective, these hydraulic valves may be characterized as being of three primary types which are:

• Hydraulic Pressure Control Valves.
• Hydraulic Flow Control Valves.
• Hydraulic Directional Control Valves.

What is a Cartridge check valve?

Cartridge check valves are designed to allow flow in one direction and stop oil/hold pressure in the opposite direction. These kinds of valves are normally used as a load-holding or pressure-blocking valves. They are made of valve body, spool, spring and seals.

What are the two main types of cartridge valves?

Cartridge valves are commonly poppet valves, but can also be spool valves instead. Poppet type cartridge valves are 2-way valves, and spool type valves come in 2-way, 3-way, or 4-way designs. There are two main types of cartridge valves: slip-in type and screw-in type.

What is a cartridge solenoid?

Cartridge solenoid valve will control which element the hydraulic fluid will flow to. Normally, valve designed with coil and cartridge spool or poppet . The valve is generally specified by number of positions and number of ways (ports). The valve is made up of two parts, the body and the spool.

Which DC valve is mostly used in hydraulic system?

The most common directional control valve is a 4/3-way valve, which means the valve has four working ports and three spool positions. The 2-way directional control valve is the simplest directional control valve that has two ports called inlet and outlet.

How many type of valve are there?

Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc. Each of these types has a number of models, each with different features and functional capabilities.

How does a cartridge valve work?

Cartridge valves, also known as 2/2–way valves or logic valves, have two operational ports A and B. The flow path between these two connections is controlled hydraulically by a pilot pressure applied to X.

What is the primary functional difference between screw in and slip-in cartridge valves?

The function and performance of screw-in cartridge valves are the same as in-line or subplate-mounted valves. Slip-in cartridge valves are different because — except for pressure controls — they are simply 2-way, bi-directional, pilot-to-close check valves.

Which is a logic valve?

Logic valves are essentially high flow poppet or spool elements that are controlled by small pilot devices. They can be used to control flow, pressure, or direction, and when applied in the proper arrangements, can perform multi-task control functions.
