The development trend of the thread cartridge valve represents the development trend of the hydraulic valve to a great extent such as stainless steel hydraulic ball valve, but it has its characteristics.
One of the biggest advantages of hydraulic technology is the large energy volume ratio, and the most important one is the high pressure that you can measure with an electronic pressure gauge. The working pressure has risen to 35-42mpa or even 48mpa today. However, in most applications, it is still between 21-35mpa. Nowadays, the working pressure of the pump has reached 42MPa and the peak pressure is 48mpa, which requires that the pressure of the valve like stainless steel ball float valve must be above 42-48mpa. At present, from the perspective of materials and applications, 35-42mpa is going to be economical and reasonable.
The increase in valve diameter means a constant increase in valve flow. The maximum diameter of screw cartridge valve is M48 × 2, the flow rate of throttle valve can reach 1600L / min, the flow rate of the logic valve can reach 800L / min, the flow rate of one-way valve is 640l / min, the flow rate of balance valve and flow valve is 200-480l / min. This size is the largest of all screw cartridge valves available. On the other hand, the valve-like stainless steel ball valve can be reduced to a smaller direction for a small flow range, such as less than 5L / min, which is difficult in other valve types. And different valves have different prices like 2 inch stainless steel ball valve price.
There are generally three measures for the development of the screw cartridge valve to a large flow rate: First, increase the diameter, but limited by the electromagnetic attraction of electromagnet, so the development of electromagnet also needs to be strengthened. Second, the structure of the valve with the logic main valve is adopted, and the flow amplification depends on the logic valve of the main valve. Third, a higher working pressure difference is adopted.
One of the biggest characteristics of a screw cartridge valve superior to other valves is that it is easy to develop and has a short cycle. The development of this aspect is developing with the requirement of hydraulic applications like hydraulic shutoff valve. If the designers of the main engine industry are familiar with the process requirements of the main engine, they should also know more about the hydraulic thread cartridge valve.
At present, the best control precision of proportional control, balance valve, and diverter valve of the screw cartridge valve is less than that of the plate valve. The linearity is poor, which is one order of magnitude worse than that. This is because the main market is construction machinery, and its load control precision is not high, which can meet the basic requirements. However, if the screw cartridge valve wants to enter the field of industrial hydraulic rubber hose manufacturer, this control accuracy can not meet the requirements, so there is still a lot of room for development.
The material selection of the screw cartridge valve is closely related to product performance and service life, unlike the plate valve which has been finalized. The development of stainless steel, non-ferrous metals, and surface treatment, so that the threaded cartridge valve into the water hydraulic field which relates to the hydraulic transmission system. Because the threaded cartridge valve has got rid of the bondage of the valve body, it has more room for application in material and is a good optional valve for water hydraulic and other occasions in the future.
The age of bus technology has arrived. Now, multinational corporations have developed a bus communication control system which can be used in all hydraulic components, which makes the hydraulic control system enhance the reliability from the aspect of electronic control.
At present, most of the digital ball valves adopt the thread cartridge structure, because the digital valve is mainly used as the pilot valve, and the diameter is small, so it is more suitable to use the threaded cartridge structure. It is also one of the directions to seek a new control mode which is easily to combine with computer technology and reliable and cheap in the future.
The parts of the thread cartridge valve have many small specifications and the overall value of a single valve is limited. Therefore, the production management mode is different from that of the plate valve and puts forward new requirements. Especially for the existing foreign specialized factories, the annual output of one factory is 6 million pieces, which is equivalent to the production quantity of hydraulic parts in China in 1998. Nowadays, Jazzy has been a big company that has a complete product line. And there are various products such as hydraulic ball valve.
The Jazzy family of dependable high-pressure ball valve offers full, unlimited flow an d positive shutoff of fluids and gases under service conditions. Jazzy valve can be used various fluids and gases including petroleum based on oil.
