Description: To ensure safety, the drilling pump is equipped with safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope. The high pressure safety valve is forged by high quality structural alloy steel. As a kind of protection device and human safety device, it is generally installed on cementing devices, fracturing pump, high pressure operation piping, pressure vessel and devices under high pressure and high flow capacity. It controls elastic force of the valve seat by adjusting the nut on the top. Once the pumping pressure or piping pressure exceeds pre-established pressure value, safety valve opens automatically to release the pressure. When the pressure value reaches the normal value, valve rod will recover the position by spring and close the valve.

Our pressure relief safety valve is designed as a pop up type valve. On exceeding set pressure the valve opens to discharge the excess built up pressure. After relieving excess pressure, the valve automatically returns to the original position. The bronze internals (Seat & Plug) ensure that there is no leakage while in operation. By replacing only the spring it is possible to change set pressure range.

AAK hydraulic relief valve is resistant to high pressure and is not stuck. Ernst doesn't want to change the supplier any more Ernst is from a German hydraulic equipment company. He has been doing well in recent years, and his boss is optimistic about him. The hydraulic relief valves purchased this time has suffered a big setback. In the second half of last year, the hydraulic power unit sold by their company for less than 3 months was complained by customers. When the pressure of the hydraulic relief valve was adjusted to 450bar, the equipment idled. The engineer thought that it could be solved by changing the motor. As a result, after the equipment started for a while, the same situation happened again. The engineer checked each component, and it turned out that the spool of the hydraulic relief valve was stuck. After the boss knew about it, he asked Ernst to request the original hydraulic relief valve manufacturer to solve the problem and bear the motor cost twice. Per the manufacturer, the price of the hydraulic relief valve is too low this time. Under the high pressure of 450bar, it is difficult to avoid a few stuck occasionally, then there is no further news. Ernst had no choice but to find new hydraulic relief valve suppliers. Ernst contacted more than 10 factories and requested that the hydraulic relief valve be 100% free of jamming within 1 year under the high pressure of 450bar. Only two factories were willing to cooperate with the samples, and other manufacturers gave up directly. Ernst still seemed worried about wasting time. With the introduction of his friend Steven, who is our old customer, he contacted AAK hydraulic valve. Ernst asked us to make samples directly according to his hydraulic relief valve drawings and working conditions. The key of this hydraulic relief valve is how long the service life of the hydraulic relief valve is under 450bar high pressure? Actually, AAK has already mass produced hydraulic valves with similar requirements. Nine months later, Ernst informed by e-mail that the hydraulic relief valve from one factory had been on strike because of its stuck, and the other factory's, although still working, it was estimated to be less than 12 months. After 9 months of use, the parameters of AAK hydraulic relief valves are still stable and function normally. Ernst said that compared with more than 10 factories, AAK high-pressure hydraulic relief valve has the most stable performance and longest service life among all the manufacturers he knows. Ernst estimated that he would not need to change the hydraulic relief valve suppliers any more. AAK hydraulic relief valve has 3 advantages and has already surpassed its domestic counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and its own upgraded and refitted independent fixture, which eliminates human errors. The high-precision control of component processing is the key point to prevent jamming.

The angle error of inner cone of AAK hydraulic relief valve sleeve is controlled within ± 0.8 , and the minimum axial grinding tolerance of sealing circle is 0.07m. At the same time, it is inspected by three coordinate measuring instrument to ensure that the hydraulic relief valve is 100% leak free. After comparing more than 10 hydraulic valve manufacturers, Backhaus determined that AAK hydraulic valve is the most reliable hydraulic relief valve manufacturer. At present, in the manufacturing process of hydraulic relief valve, when grinding the conical surface inside the valve, most hydraulic valve manufacturers just let the operator judges the feed rate, angle control and grinding tolerance by experience completely. There is no grinding amount detection link, and there is no precision detection of each part in the valve. When this type of common quality hydraulic relief valve is used on equipment with high requirements, troubles will come out. Backhaus is a purchaser of a German hydraulic pump company for less than a year. In the first half of the year, a batch of hydraulic pumps of their company were complained by customers. After the hydraulic pump is started, the system pressure begins to lose stability and there is pressure drift. The engineer judged that there was a problem with the hydraulic relief valve. After disassembly, it was found that there was a gap between the valve sleeve and valve spool of the hydraulic relief valve. After measurement, it was found that the error of the cone angle in the valve sleeve of the hydraulic relief valve was too big and caused leakage of the hydraulic relief valve. The only solution is to replace the hydraulic relief valve. It is estimated that 30% of hydraulic relief valves need to be replaced. The owner asked Backhaus to replenish the goods as soon as possible and solve the customer complaints. Backhaus contacted the original manufacturer of the hydraulic relief valve. The manufacturer was willing to replenish. Backhaus thought it would be all right after replacing the hydraulic relief valve. A month later, the customer complained again, which is still the same problem. This shows that the quality of the hydraulic relief valve from the old manufacturer is not trustworthy, and it is urgent to replace the hydraulic relief valve supplier. Backhaus contacted more than 10 hydraulic relief valve manufacturers, including AAK hydraulic valve. The hydraulic relief valve is required to be 100% leak free. AAK hydraulic valve and other 3 manufacturers are required to send samples for testing according to his hydraulic relief valve drawings and working conditions. A month later, Backhaus asked us about the production time of replenishing 30% hydraulic relief valve. It should be that AAK hydraulic relief valve has been recognized by the customer.

On Monday afternoon, I received an email from Tony. Tony is a purchasing manager of CASAPPA in Italian, mainly responsible for the purchasing of hydraulic pump components, and the work has been very smooth. Last month, they received a complaint from the largest customer that the pressure at the outlet of the hydraulic pump sometimes rises by itself, resulting in unstable operation of the equipment. The customer's site engineer couldn't solve it and turned to CASAPPA for after-sales service. Although the warranty period has expired, they still need to help customer solve the problem. Their engineers tested various parameters of the hydraulic pump. After comprehensive analysis, they were still uncertain about the root cause, but they suspected that the hydraulic pressure relief valve in the pump is faulty. The engineer asked Tony to contact the original supplier of the hydraulic pressure relief valve and ask him to send a sample of the hydraulic pressure relief valve for replacement and test. It is a local hydraulic valve manufacturer and they still have samples in stock. After receiving samples and commissioning, the engineer's suspicion was proved to be correct. After replacing the hydraulic pressure relief valve, the hydraulic pump worked normally. Tony asked the original hydraulic valve manufacturer to urgently replenish 30 hydraulic pressure relief valves to solve this complaint. The manufacturer said that the shipment has passed the two-year warranty period. At present, there are only 3 samples in stock. The remaining quantity needs to wait in production schedule for production, and can only be delivered after 3 months. If offering this plan to the big customer, Tony would be scolded by the boss. He thought of AAK, because the hydraulic valve failed last year, which was also solved by AAK. Tony established a business relationship with us last October. Now we are also friends besides business. We often discuss the knowledge related to hydraulic valves. His email on Monday is just to ask for help on this hydraulic pressure relief valve. After knowing these conditions, I asked him to send us samples of those faulty hydraulic pressure relief valves, and provide us the drawings of this hydraulic pressure relief valve, noting those special requirements. After receiving and disassembling the samples from Tony, we found that the main valve spool of the hydraulic pressure relief valve was too loose and had increased leakage, then the pressure at the oil outlet increased. The problem should be caused by high-frequency wear or insufficient accuracy of the original shipped hydraulic pressure relief valve. The engineer of CASAPPA asked us to reply why it was determined that it was the problem of the valve spool?
