Excavator solenoid valve hydraulic pump 12V 25/974628 threaded cartridge valve Hydraulic valve

     Hydraulic screw cartridge valves were produced in the 1950s, grew up in the 1970s, and gradually developed into almost all types of valves covering direction control, pressure control, flow control, with comparison control pressure valves, proportional control flow valves, proportional control direction valves, etc., forming an independent system. It has the advantages of small size, compact structure, small internal leakage, flexible application, low price, simple installation and maintenance, and is widely used in construction machinery.

Hydraulic screw cartridge valve introduction

    Hydraulic screw cartridge valve is also called screw cartridge valve, its installation method is to screw directly into the jack of the valve block, installation and disassembly is simple and quick, generally by the valve sleeve, valve core, valve body, seals, control parts (spring seat, spring, adjusting screw, magnetic body, electromagnetic coil, spring washer, etc.) composition. In general, the valve sleeve and the valve core and the spiral part of the valve body are screwed into the valve block, and the rest of the valve body is outside the valve block. Specifications are two, three, four and other threaded cartridge valves, diameter from 3 mm to 32 mm, the maximum pressure up to 63MPa, the maximum flow of 760L/min. Directional valves include check valve, hydraulic control check valve, shuttle valve, hydraulic reversing valve, manual reversing valve, solenoid slide valve, solenoid ball valve, etc. The pressure valve has relief valve, pressure reducing valve, sequence valve, balance valve, pressure difference relief valve, load sensitive valve, etc. The flow valve has throttle valve, speed regulating valve, shunt collecting valve, priority valve and so on.
