Excavator selection valve PC120-6 Solenoid valve Relief valve 709-20-81201

         Threaded cartridge direction valves include check valve, hydraulic control check valve, shuttle valve, hydraulic reversing valve, manual reversing valve, solenoid slide valve, solenoid ball valve, etc. The screw insert pressure valve has relief valve, pressure reducing valve, sequence valve, balance valve, pressure difference overflow Valves, load sensitive valves, etc.; The threaded cartridge flow valve has throttle valve, speed regulating valve, shunt collecting valve, priority valve and so on. Threaded cartridge valve has two, three, four and so on
 

   Applications

       Threaded cartridge valve in the late 1980s has been applied to the hydraulic device of construction machinery, such as hydraulic pump there are many threaded cartridge valve integrated in it, have developed a multi-function valve specially used for pump; Threaded inserts are often used in hydraulic motors, especially in closed circuit motors
Valve; In addition to the directional valve, the integrated safety valve, check valve, overload valve, oil supplement valve, shunt valve, brake valve, load sensitive valve, etc., are threaded cartridge valves; Often at the oil port of the hydraulic cycloidal motor
Equipped with special threaded cartridge valve group: In construction machinery, superimposed valves and plate valves composed of threaded cartridge valves are often used: threaded cartridge valves are mostly used in the control loop, and the pilot control valves in the two-way cartridge valve cover plate are many threaded cartridge valves.

Cartridge valves provide equipment designers with many advantages in terms of conventional integrated valve blocks:

      1. System integrated valve block simplifies the machine pipeline.
Designing the valve block to meet the requirements of the equipment is better than designing the equipment to meet the requirements of the hydraulic system. Installation costs are usually significantly reduced

       2. Stop leaks.
External leakage is often the main reason for the limited application of hydraulic systems, and the O-ring fitted to the valve hole on the integrated valve block can eliminate external leakage.
