Cartridge valve working principle

August 28, 2018

Cartridge Valves are a generic term for another type of Hydraulic Control Valve. The basic core component is a liquid-controlled, single-control, two-way liquid-resistive unit installed in the main section of the oil circuit (it is also called a two-way Cartridge Valve). Different combinations of one or several plug-in elements, together with corresponding pilot control stages, can constitute various control functional units of the plug-in valve. Then, the next small series introduces the working principle of the cartridge valve and the role of the cartridge valve.

Cartridge valve working principle

The design versatility of the cartridge valve and its valve hole is important for mass production. As an example of a cartridge valve of a certain size, the size of its valve port is uniform for mass production. In addition, valves of different functions can use the same specification of valve chambers, such as: Check Valves, poppet valves, flow control valves, throttle valves, two Solenoid Valves, and the like. If valves of the same specification and different functions cannot use different valve bodies, then the processing cost of the valve block will inevitably increase, and the advantages of the cartridge valve will no longer exist.

Cartridge valves are used in a wide variety of applications in the field of fluid control functions. Components that have been used include electromagnetic Directional Valves, check valves, relief valves, Pressure Relief Valves, flow control valves, and sequence valves. The extension of versatility in the design of fluid power circuits and the practicality of machinery fully demonstrates the importance of cartridge valves to system designers and users. Because of the versatility of the assembly process, the versatility of the valve hole specification, and the interchangeability, it is possible to use a cartridge valve to achieve a complete design configuration, and to make the cartridge valve widely applicable to various hydraulic machines.

Cartridge valve features

Small internal resistance, suitable for large flow operation; most of the valve port adopts conical sealing, so the leakage is small, suitable for low viscosity working medium such as emulsion, simple structure, reliable work, high degree of standardization; for large flow, high pressure, More complex hydraulic systems can significantly reduce size and weight.

The role of cartridge valve

1. Cut-off valve: Cut-off valve is also called closed-circuit valve. Its role is to connect or cut off the medium in the pipeline. Cut-off valves include gate valves, globe valves, plug valves, ball valves, butterfly valves, and diaphragms.

2, check valve: check valve, also known as check valve or check valve, its role is to prevent the pipeline in the media backflow. The bottom valve of the pump is also a check valve.

3. Safety valve: The function of the safety valve is to prevent the medium pressure in the pipeline or device from exceeding the specified value so as to achieve the purpose of safety protection.

4, regulating valve: regulating valve class includes regulating valve, Throttle Valve and Pressure Reducing Valve, its role is to regulate the media pressure, flow, etc.

5, diverter valve: Diverter valve class includes a variety of distribution valves and traps, its role is to distribute, separate or mix the media in the pipeline.

Editor's summary: The working principle of the cartridge valve and the function of the cartridge valve are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
