SV08-21P Hydraulic screw cartridge valve Solenoid valve spool

The threaded cartridge valve is threaded directly into the cartridge hole of the valve block, and the installation and disassembly are simple and quick. Common threaded cartridge valves are generally composed of spool, valve sleeve, valve body, seals and control components (spring seat, spring, adjusting screw, spring washer, etc.).
During installation, the valve sleeve and the valve core and the threaded part of the valve body are all screwed into the valve block, and the rest of the valve body is outside the valve block. Therefore, it has the characteristics of compact structure, small size, light weight and easy installation.
According to the role in the hydraulic system, threaded cartridge valves can be divided into direction control, pressure control, flow control and other types. Common direction control valves include check valve, hydraulic control check valve, shuttle valve, hydraulic reversing valve, manual reversing valve, solenoid slide valve, solenoid ball valve, etc. Pressure control valves include relief valve, pressure reducing valve, sequence valve, balance valve, pressure difference relief valve, load sensitive valve, etc.
Flow control valves include throttle valves, speed regulating valves, diverting collector valves, priority valves, etc. Specifications are two, three, four, etc., the internal diameter is 3~32mm, the maximum pressure reaches 63MPa, the maximum flow rate reaches 760L/min.
Threaded cartridge valves make the design of hydraulic control systems more flexible. In recent years, Chinese hydraulic industry designers also pay more and more attention to the development of threaded cartridge valves, and gradually began to try to use threaded cartridge valves to form a hydraulic integrated system, simplifying the installation form of the system, the advantages of threaded cartridge valves:
(1) Easy maintenance, replacing a cartridge valve is as simple as replacing a bolt;
(2) Complete specifications and varieties, there are many kinds of threaded cartridge valves, and the series can meet various functional requirements;
(3) High degree of standardization, threaded cartridge valve of various types of products basically have a unified standard, easy to exchange and replace
