To lose a large amount of money in the Hydraulic Flow Control Valve, AAK used a small amount of money to ease the worries of Brazilian customer
Bernardo comes from a hydraulic winch manufacturer in Brazil, and has cooperated with AAK several times on non-standard customized hydraulic cartridge valves. At the beginning of last year, Bernard company needed to purchase hydraulic flow control valves for a batch of hydraulic winches. Due to cost pressure, the boss asked Bernard to reduce the procurement cost of hydraulic flow control valves by 10%. This hydraulic flow control valve needs to be the same as HydraForce standard part. After a round of sourcing, Bernard determined the manufacturer of the hydraulic flow control valve. 7 months after the sale of the hydraulic winch, a customer complained that the sealing ring of the hydraulic flow control valve was broken, resulting in leakage, which caused the hydraulic winch to rise powerlessly. 6 months after the original manufacturer replaced the sealing ring with new one, the old problem happened again. The customer complained directly to the boss, who asked Bernard to replace all the hydraulic flow control valves within 1 month and asked the original manufacturer to bear the costs. However, the original manufacturer could not reach an agreement. Bernard was caught in the middle. He was embarrassed for 2 weeks and made no progress. The boss was very disappointed with him.
Bernard sent me an email asking about the time and cost of re producing the hydraulic flow control valves. He wanted to pay for it himself. According to the hydraulic flow control valve drawings he sent, I realized that maybe only replacing with durable O-ring could solve his embarrassment. I sent him 10 O-rings for matching tests. A week later, Bernard told me that AAK O-rings could be matched with the original manufacturer's hydraulic flow control valves. He asked me to send 500 O-rings to Brazil as soon as possible, and he could finally have a good sleep.
Last week, Bernard sent an e-mail to express his thanks. All these hydraulic flow control valves have been assembled with AAK O-rings. It has been more than a year, and there has been no complaint of leakage caused by the rupture of the sealing ring of the hydraulic flow control valves. The boss also praised him for solving big losses with small money.
AAK's O-ring has 3 strengths: no sloughing, no extrusion and wear resistance. The material and structure of the seal ring directly affect the performance of the seal ring. The hardness, extrusion resistance, tensile strength and deformation of the material all determine the service life of the seal ring, and the structure of the seal ring also determines the sealing effect. AAK selects Japan's special PU polyurethane rubber sealing ring, and the lip compression of the sealing ring is strictly controlled between 15% ~ 20%.

Globe Valves For Flow Control
Globe valves are used to regulate flow in pipelines and consist of a removable disc (also known as a plug) element and a fixed ring seat usually located in a spherical valve body. The inlet and outlet of the globe valve body are separated by an internal baffle. The baffle has an opening that forms a seat into which the removable disc/plug can be screwed to close (or shut off) the valve.
Common Applications
Globe valves are available in a variety of sizes (NPS 1/2 through 36) to provide users with high performance and reliability. They can help solve a variety of application needs from large to small, hot to cold, and general to severe.
Bonnets are available in a variety of styles to accommodate different application temperatures. These primarily include standard bonnets and optional extension bonnets that can be used to protect the packing when the valve is used in extremely hot or cold applications.
Special packing configurations are also available for applications where a packing system is required to keep fugitive emission concentrations below ambient standards.
Over the past year, Jerome has purchased more than 20 batches of different types of hydraulic valves of test orders from more than 10 hydraulic valve manufacturers in Ningbo, including AAK. Finally, he chose to place the large order of hydraulic flow control valves with AAK, because the packaging details of AAK made him think that the quality of AAK hydraulic flow control valves is the most reliable.
Jerome is from a hydraulic equipment company in Italy. He sent an email last week to purchase 2,500 hydraulic flow control valves. I was surprised because Jerome always purchased small orders before. After e-mail communication, it was learned that Jerome has purchased more than 20 batches of different types of hydraulic valve test orders from more than 10 hydraulic valve manufacturers in Ningbo in the past year. There are always some problems, such as time delay and communication delay, especially the packaging of the test order was criticized by his boss.
The quality defect of the hydraulic flow control valves purchased last time was complained to the boss by the company's installation engineer. During the assembly process, the installation engineer found that several hydraulic flow control valves could not be screwed into the socket at all, mainly due to obvious bumps at the threads of the hydraulic flow control valves. Jerome requires the original hydraulic flow control valves to be replaced. The manufacturer believes that each hydraulic flow control valve has been pressure tested before leaving the factory and shipped only after it is qualified. The bump was caused by the carelessness of their installers. The installer showed the boss of the damaged package photos to reveal the reason. Some of the packing boxes of the hydraulic flow control valves are deformed, some are broken, and even some of the inner packing poly bags are broken. Those hydraulic flow control valves with bumps were improperly packaged and protected during transportation. Jerome is helpless because of the factory's prevarication. Fortunately, this is just a trial order.
Jerome thought of the packaging details of each trial order of AAK. Only the packaging of AAK was different from that of other hydraulic valve manufacturers in Ningbo. At that time, it was only the trial order that he didn't pay attention to the packaging details of AAK. Now he saw the problems caused by improper packaging during transportation from other hydraulic valve manufacturers. He realized that only each trial order of AAK, the packaging received was intact.
Later, I told him that because the quantity of trial orders was small, most of them were delivered by express, and it is unavoidable that the parcels will be bumped. AAK will inspect each hydraulic flow control valve separately when leaving the factory. Only the qualified hydraulic flow control valves are put into the bubble bag and then into the corrugated box with the right size,
Just yesterday, I received a repeat order from Andy for a hydraulic flow control valve, which is just 3 months away from the delivery time of the last batch of hydraulic valves. The American customer Andy, started to communicate with us in 2019. Maybe it was just not the right time, we still didn't partner with each other till the beginning of this year. Because of encountering a Waterloo at the previous hydraulic valve manufacturer, he turned the tables at AAK and regained his confidence.
At the end of last year, Andy purchased a batch of hydraulic flow control valves from a hydraulic valve manufacturer. Because 20% of the shipments leaked, he encountered customer claims. The old hydraulic valve manufacturer was unwilling to bear the claim or re-produce. The customer kept pushing for replacement hurriedly. The owner asked him to find a high-quality hydraulic valve manufacturer to reproduce the goods for the customer.
Andy had a big headache at that time. The replacement quantity is not big, the hydraulic valve manufacturers with exquisite quality were unwilling to produce the small quantity for him. The hydraulic valve manufacturers who were willing to produce this quantity, were not able to meet the customerâ??s requirement about the roughness of hydraulic flow control valve. He ran into a wall everywhere, which made Andy haggard.
When Andy contacted with AAK HYDRAULIC VALVE, we are willing to cooperate with her to solve this difficult problem. We tested the leaked hydraulic flow control valve sample. The reason for the leakage is the roughness of the mounting surface of the hydraulic flow control valve. According to the customer's service conditions, this roughness must be controlled at 1.0 �¼ M or less. Andy is very confused why 80% of the installation surface roughness of hydraulic flow control valve is up to standard, while 20% is out of this range. The root of this fluctuation is the master's operation method, resulting in human error. The surface roughness is the depth, density, texture of the traces left on the machined surface from the action between the tool and the part surface, which depends on the master's processing technique.
Andy is very clear that at present, most domestic hydraulic valve manufacturers generally control the roughness of the installation surface of hydraulic flow control valve at 0.8-1.0 �¼ m. The biggest problem is not stable enough. Andy also knows that only AAK controls the roughness value of hydraulic flow control valve within 0.8 �¼ M, which can completely avoid leakage outside the hydraulic flow control valve, because of rest assured, Andy decided to repeat the order with AAK HYDRAULIC VALVE.
