Direct Operated 5 Way Sol. Valve YVS

Trace the history of development, so far, both at home and abroad in principle can be divided into three categories (i.e., straight acting, step by step child guiding type), and from a disc structure and material of the difference between the different and in principle is divided into six branches small class (diaphragm structure, step by step of moving heavy piece of membrane structure, the structure, the forerunner in straight moving piston structure, step by step piston structure, the forerunner of moving piston structure).

Products Details

It is used to control the flow of automatic basic components, belongs to the actuator;It's not limited to hydraulics, pneumatics.Is used to control the direction of hydraulic flow, the mechanism of the factory are controlled by the hydraulic cylinder, so can use it the working principle of the sealed cavity, open a hole in different locations, each hole leads to different tubing, cavity valve is among, both sides are two electromagnets, which face the magnet coil electricity body will be attracted to which side, by controlling the movement of the valve body blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push oil just the pistons, piston drives the piston rod, piston rod drive mechanism.The mechanical motion is thus controlled by controlling the current of the electromagnet.Principle: When electrified, the electromagnetic force generated by the electromagnetic coil will lift the closing part from the seat and the valve will open.When the power is cut off, the electromagnetic force disappears, and the spring presses the closing part on the seat and closes it. Features: it can work normally in vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.

Principle: it is a kind of direct action and pilot type combination principle, when the inlet and outlet have no pressure difference, after electrization, the electromagnetic force directly pilot small valve and main valve close part in turn up, the valve opens.When the inlet and outlet reach the starting pressure difference, after electrization, electromagnetic force pilot small valve, the pressure of the main valve lower chamber rises, the pressure of the upper chamber drops, so as to use the pressure difference to push the main valve upward;When the power is cut off, the pilot valve USES the spring force or the medium pressure to push the close part, moves downward, makes the close. Features: in zero pressure difference or vacuum, high pressure can also be action, but the power is large, the requirement must be horizontal installation.
