The use of cartridge valves in hydraulic systems
Cartridge valve is the generic name for another type of control valve for hydraulic machines. Its basic key component is a hydraulic valve type, single control port mounted in the main stage of the oil channel of the two-way hydraulic resistance unit (so also known as two-way cartridge valve).
(hence the name two-way cartridge valve). One or more cartridge components will be developed in different compositions, and with the corresponding dominant control level, can constitute a variety of cartridge valve control unit. For example, orientation control
The cartridge valve has the following characteristics: the internal pressure control unit, the operating pressure control unit, the total flow control unit and the composite control unit.
Cartridge valves have the following characteristics: low internal resistance, suitable for high flow rates, low leakage due to the spherical sealing of most of the valves, suitable for high viscosity substances such as emulsified oils, etc.
Simple construction, reliable work, high level of standardisation; Zhenhai integrated valve set for high flow, high working pressure, more complex hydraulic system can significantly reduce the specifications and net weight.
It is composed of three vast majority of cartridge elements, control back cover and safety channel block. The cartridge element is composed of valve core, valve sleeve, torsion spring and hydraulic seal; the control back cover plate according to the different control of the cartridge valve
The safety channel block is the basic oil circuit board for inserting components and installing the control back cover, which is also the main oil channel and the control oil channel as a whole.
Depending on the more complex composition, a large number of hydraulic solenoid valves can be used.
According to the composition, the cartridge valve can be used as a working pressure control valve (speed control valve, pressure regulator), total flow control valve (one-way throttle valve, one-way throttle valve), orientation control valve (speed control valve, hydraulic control valve single
directional valves, two-way hydraulic directional valves, etc.) and their composite valves.
At this stage, the integrated valve group custom cartridge valves have the following series of products: K series cartridge valves, L series cartridge valves, TJ series cartridge valves, Z series cartridge valves. There are several series of products with different specifications.
The manufacturer can design and manufacture an integrated safety channel block according to the customer's specifications. Cartridge valves are commonly used in hydraulic systems according to their characteristics.
