　　191.019.01 Saich SEITZ pilot valveWhat is its function?

　　191.019.01 Saich SEITZ pilot valve is an auxiliary valve used to operate the control mechanism in another valve or component. The pilot valve consists of a wet valve solenoid, valve core, drive plunger, valve sleeve, push rod, steel ball, ball seat, return spring, etc. The hard-sealed butterfly valve core is connected to the valve body by threads. One end of the drive plunger is connected to the solenoid armature, and the other end is supported by a steel ball. Therefore, the thrust at the upper end of the solenoid and the force at the lower end of the spring create a connection between the two balls and the push rod. An annular control chamber is provided between both ends of the push rod and the valve core, and the control chamber communicates with the radial holes on the valve core. This is a two-position three-way double ball normally closed solenoid valve.

An annular control chamber is provided between both ends of the push rod and the valve core, and the control chamber communicates with the radial holes on the valve core. This is a two-position three-way double ball normally closed solenoid valve. When the solenoid is energized, the pressure oil entering the P chamber directly acts on the pilot valve seat, while the elastic force of the return spring also acts on the ball seat, causing the valve port under the pilot valve to close, and the valve port to open, blocking the pressure oil circuit and opening the control oil circuit A and the return oil circuit T. At this time, the control oil circuit is in a relieved state; when the solenoid is energized, the drive plunger presses the ball down, closing the upper valve port and opening the lower valve port. Thus,191.019.01 Saich SEITZ pilot valvethe passage between the control oil circuit and the return oil circuit is blocked, and both the pressure oil circuit and the control oil circuit are opened simultaneously. The pressure oil enters the valve body through the control chamber of the pilot valve, putting the control oil circuit into working condition. The pilot valve is an auxiliary valve used to operate the control mechanism in another valve or component. The pilot valve itself is often a small-sized control valve, mostly pressure control valves. It consists of a pilot control liquid bridge with fixed liquid resistance, controlling the main valve or sub-valve or variable rod according to the input signal; it can accept various input methods, such as manual, electric, hydraulic, pneumatic, mechanical cam, electric ratio, etc. The Price of the pilot valve mainly depends on the Size and quality of the pilot valve. Generally, the Price of a pilot valve is around a few hundred yuan, while a slightly more expensive pilot valve will cost around a few thousand yuan, with significant Price differences. Generally speaking, if you want to purchase a pilot valve, you should first understand the Model, Brand, Price, and other related information of the pilot valve. In addition, if the seller is different, the same pilot valve may also vary, and at different times and in different regions, the Price of the pilot valve will also differ. When purchasing a pilot valve, the main parameters or consulting the guiding valve and specifications should be noted, but also pay attention to the Brand and After-sale Service of the pilot valve to avoid trouble in using the pilot valve later, which can be resolved in a timely manner.
