AAK HYDRAULIC VALVE Classified the Types of Hydraulic Cartridge Valves from the Perspective of Installation, and Berge Puts Down His Uneasy Heart
The types of hydraulic cartridge valves can be classified from different angles. Sometimes, buyers who purchase hydraulic cartridge valves are confused. After all, they are not engineers. In order to classify more simply and intuitively, AAK HYDRAULIC VALVE describes the types of hydraulic cartridge valves from the most extensive installation point of view. In this way, we can divide the hydraulic cartridge valves into 3 types: Insert-type, Slide-in and Screw-in.
Berge, an old British hydraulic valve customer, was transferred from the quality control department to the import department. He is a very studious buyer. Maybe it's fate, we often discuss some knowledge points about hydraulic valves. Some time ago, he didn't understand that every time, when the domestic hydraulic valve manufacturers receive an inquiry about his hydraulic cartridge valve, they always ask about the type of hydraulic cartridge valve. The question about the type of hydraulic cartridge valve made him very nervous and helpless.
Indeed, there are many types of hydraulic cartridge valves now, from the perspective of function, hole type and scene. We found that they are most commonly classified from the perspective of installation, which is easy to understand and remember. I summarized our hydraulic cartridge valve types to Berge. After reading my following report about the types of the hydraulic cartridge valves, he told me that this classification for the hydraulic cartridge valve types can basically cover more than 80% of the hydraulic cartridge valves. Here, I'll also share with you the types of hydraulic cartridge valves I gave him.
Common types of hydraulic cartridge valves are as follows:
The Insert-type hydraulic cartridge valves: completely enters the inside of the valve block and does not expose any part outside the valve block. It is positioned by its own thread or other components such as pipe joint, snap ring, retaining ring etc. For example, hydraulic check valve and two-way hydraulic flow regulating valve have this design.
The slide-in hydraulic cartridge valves: it does not have installation threads itself, and the valve spool needs to be used together with the cover plate. The valve spool is integrated in the valve block to switch the oil circuit on and off through pressure and spring force. Different cover plates are used to realize direction control, pressure control and flow control.
Screw-in hydraulic cartridge valves, that is, hydraulic threaded cartridge valves, have different brands and different hole types, which are usually unable to be interchanged in installation. At present, there are 3 commonly used pass types: ISO7789, SAE and SUN.
At the beginning of this year, received an order from African customer for excavators with a delivery time of 2 months, which means that all accessories must be in place within 1 month, including 600 hydraulic cartridge valves. The production time for the factory is a little more than 2 weeks. The purchaser Peter sent the order information of the hydraulic cartridge valve to all the hydraulic valve manufacturers he contacted before at the first time. More than 20 hydraulic valve manufacturers said that they could not complete the order of the hydraulic cartridge valve in such a short time, and it would take at least 3 - 4 weeks. His supervisor was not satisfied with this delivery time and asked him to find a new hydraulic valve manufacturer. After the email was sent, there was basically no sound. Peter was very helpless and worried. Peter asked Mark for help. HYDRAULIC VALVE to ask if could produce 600 hydraulic cartridge valves in 2 weeks and CC Peter, and joking at the end of the email that if HYDRAULIC VALVE could not complete the hydraulic cartridge valve order, then there is no need to waste time on looking for a new hydraulic valve manufacturer. According to the drawings they sent, technical department found that this was very close to the hydraulic cartridge valve supplied to a Russian customer last year, so the time in the early stage of the production of the hydraulic cartridge valve was saved. After the price of the hydraulic cartridge valve was approved, the process data could be configured on the computer on the same day and the production could be carried out the next day. 2 weeks later, 600 hydraulic cartridge valves were delivered on time, which was the first of all the accessories purchased by Peter to arrive at the company's warehouse. Peter didn't expect that the hydraulic cartridge valve he was most worried about was the first to be completed. Peter appreciated the advice from Mark and was also surprised that could complete this in 2 weeks, while his previous hydraulic valve suppliers needed 3-4 weeks. Mark told : 1. is his most trusted hydraulic valve manufacturer. can surprise him every time when the hydraulic valve order is urgent. 2. has a large amount of data storage and clear classification. For hydraulic valves with relevant data, they can use the most advanced UG / SOLIDWORK software and finite element analysis method to configure process data in 2 hours, which is 3-6 times faster than that of other suppliers. 3. is equipped with advanced machine tools imported from Swiss, coupled with their own modified fixtures, the production speed is accelerated and man-made errors are avoided at the same time. After listening to the introduction realized that only a good hydraulic valve supplier can make his purchasing smooth. successfully completed this urgent order.

In Google, enter the types of hydraulic valves, and you can get a series of information about the types of hydraulic valves. It looks like that each description about the types of hydraulic valves are all right. This makes Berge a very big headache. He transferred from the quality control department to the import department. He is a very studious buyer. Every time, when domestic hydraulic valve manufacturers in China receive his design drawings, they ask a lot of questions about the types of hydraulic valves. Berge asked me how to clearly understand the types of hydraulic valves expressed by hydraulic valve manufacturers and how AAK classifies the types of hydraulic valves. I gave him an example. If there are a pile of stools there with various shapes and materials, how should we classify them? Firstly divide the same kind of materials together, and then classify them for the second time to put different shapes together. This simple dichotomy is also suitable for the types of hydraulic valves. What is a hydraulic valve? It is a hydraulic element used to control liquid pressure, flow and direction in hydraulic transmission. Letâ??s classify the types of hydraulic valves for the first step: A. The types of hydraulic valves are divided into 3 categories according to their functions: directional control valve (such as one-way valve, reversing valve etc.), pressure control valve (such as relief valve, sequence valve, pressure reducing valve etc.), flow control valve (such as throttle valve, speed regulating valve etc.). B. According to the operation, the types of hydraulic valves are divided into manual valve, motorized valve, electric valve, hydraulic valve etc.. C. According to the control, the types of hydraulic valves are divided into Control valve, Cartridge valve and sandwich plate valve. D. According to the installation, the types of hydraulic valves are divided into threaded connection valve, plate connection valve, integrated connection valve, Superposition valve and cartridge valve Then, let is classify the types of hydraulic valves for the second step. From above A category, if according to the installation, you will get the sub-category of the types of hydraulic valves, for example, the threaded hydraulic pressure valve. Berge understood the dichotomy of the type of hydraulic valves immediately, especially dividing them by using stools as example, which is very practical. As soon as you listen and compare, you will understand, and can well understand the various questions about the types of hydraulic valves from different hydraulic valve manufacturers. In this way, the types of hydraulic valves are summarized from different angles. Combined with the dichotomy of the types of hydraulic valves, the types of hydraulic cartridge valves are basically clear, and they are interconnected and integrated. AAK HYDRAULIC VALVE can express any complex question about hydraulic valve to you with "analogy".
