Needle valves are usually used in flow-metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. Needle valves sometimes referred to as plunger valves. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat. These needle valves are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy.s. Our range of needle valves has been designed with durability and performance in the spotlight. These needle valves are available in a variety of sizes (1/4, ½, 1/8 inch). Our range of needle valves has been designed with durability and performance in the spotlight.

For the valve hole accuracy 1 m hydraulic needle valve, although AAK is 20% more expensive, its service life is twice that of its peers At the beginning of this year, Samuel asked by email about the production time of 1,000 hydraulic needle valves, He specially emphasized that the technical parameters of the hydraulic needle valves need to be the same as those samples made before, especially the valve hole accuracy must be 100% within 1 m or less. Samuel has been cooperating with AAK for 3 years. It is the first time that he deliberately emphasized as such in email. After communication, I learned that the hydraulic needle valves that AAK made samples for last time was 20% higher than that of other hydraulic valve manufacturers, so he placed the order with another manufacturer. However, now this batch of hydraulic needle valves have been complained by customers that the hydraulic winch is stuck. The root cause is that the accuracy of the hydraulic needle valve holes is uneven, and some are less than 1 m, and some higher than 1 m. After the original hydraulic needle valves were replaced by the manufacturer, complaints still continued. The boss was very dissatisfied with Samuel's purchase this time and asked him to source another hydraulic needle valve supplier. Samuel can only get back to AAK, because the sample accuracy of AAK hydraulic needle valve hole was 1 m or less. I told Samuel that the shipment of AAK hydraulic needle valves has never been lower than the sample standard. The next day, Samuel sent us the PO of 1,000 hydraulic needle valves. After 45 days, AAK delivered 1,000 hydraulic needle valves. Last week, Samuel sent an email saying that AAK hydraulic needle valves had been installed on the equipment for more than half a year, and no complaint was received. His boss would rather spend 20% more cost and must purchase the hydraulic needle valves with valve hole accuracy 1 m for 100%. I told him that even if AAK hydraulic needle valve is used properly in another year, it will not get stuck. Samuel was surprised at how AAK ensured 100% accuracy of the hydraulic needle valve hole within 1 m? For the control of the manufacturing quality of hydraulic needle valves, AAK's 3 characteristics lead the majority of hydraulic valve manufacturers. 1. On the processing equipment, the valve hole is finished with the TAMIX one-time tool walking high-speed ultra precision honing mill imported from Japan, which is thoroughly ground without traces. In mass production, the wear-resistant SPA tool effectively ensures the stability of processing, and the valve hole accuracy is guaranteed to be 0.8-1.0 m and the surface roughness reaches Ra0.2-0.3. 2. In the processing process, AAK has more than 10 years of experienced technicians with special machines and special personnel, who have engraved the dimensional accuracy of each element in their minds.

Carter comes from an manufacturing company in , and the purchase of hydraulic needle valves has been smooth in recent years. At the beginning of last year, an excavator sold by their company for less than 6 months was complained by customer. The boom of the excavator falls too fast due to its own weight, which is easy to cause danger. Their technician found that there was a problem with the hydraulic needle valve of the hydraulic system. There were obvious wear marks at the contact point between the valve spool and valve seat of the hydraulic needle valve, which was easy to leak. The leakage of the hydraulic needle valve will cause the oil saving and speed limiting circuit of the hydraulic cylinder to be uncontrollable. The boss was very angry that the equipment sold for only half a year was complained and asked Carter to find out the cause of the hydraulic needle valve problem and solve it. Carter contacted the original manufacturer of the hydraulic needle valves and requested to replace the hydraulic needle valves. The manufacturer said that the service life of hydraulic needle valves under 450bar working condition is basically 6 months. The only way to solve this complaint is to replace the hydraulic needle valves every 6 months. Such reply made Carter speechless, because his customer would not accept the high-frequency replacement of hydraulic needle valves, which not only brought a bad user experience, but also the after-sales cost was not cheap. Carter contacted all of his hydraulic needle valve suppliers, and they all replied that they were not sure to achieve a hydraulic needle valve with a service life of 1 year under the working condition of 450bar. When browsing the website, he found and left a message on the How long is the service life of hydraulic needle valves with pressure resistance of 450bar We replied directly for 1 year or more. The next day, he told the problems encountered in purchasing hydraulic needle valves at the beginning of last year in detail. After receiving the drawing of the hydraulic needle valve, we found that the hydraulic needle valve needed by Carter has much higher requirements than the ordinary hydraulic needle valves. We replied that will select specific materials for samples, which can ensure that the hydraulic needle valves can be used for more than 1 year under normal conditions. If possible, he can directly test the samples.

The Hydraulic Cartridge Needle valve that HydraForce can't make, AAK has done it in 30 days Rogelio is from Spain and we met 1 year ago. He sent inquiries about hydraulic cartridge valves to AAK for several times. Some time ago, he came to me and asked for help to make a batch of hydraulic cartridge needle valves. The hydraulic cartridge needle valve used on the hydraulic cold drawing machine they sold to Vietnam has expired the warranty period and needs to be replaced. This hydraulic cartridge needle valve is purchased from HydraForce, and it is not a standard part. HydraForce said that this valve was produced 2 years ago, it is out of stock now and will take 3-4 months to produce it. But the customer was not satisfied with this time frame and complained to his boss. In order to catch time, Rogelio contacted more than 10 Chinese manufacturers of hydraulic cartridge needle valves. They either could not benchmark with HydraForce, or they could not meet the time, so Rogelio was anxious. Rogelio remembered that AAK had supplied HydraForce for 9 consecutive years. He believed that I can help him. According to the hydraulic cartridge needle valve drawings provided by Rogelio, the production time is only 30 days. I told him that the lead time was only 30 days, and the manufacturing quality of hydraulic cartridge needle valve was up to the standard of HydraForce, few Chinese hydraulic valve manufacturers could meet these requirements. Rogelio thought that I was ready to give up, he was willing to give AAK 40 days and paid for 100 hydraulic cartridge needle valves the next day. 30 days later, AAK sent 100 hydraulic cartridge needle valves to their Vietnam factory. Rogelio informed by email last week that it was out of his expectation that AAK still completed the production in 30 days. Their customer was very satisfied with their replacement of the hydraulic cartridge needle valves. Rogelio also specifically mentioned that he had asked more than 10 hydraulic cartridge needle valve manufacturers, their lead time was at least 50 days and can not 100% guarantee to benchmark the manufacturing quality of HydraForce. AAK was the only one that could catch up with the delivery date and also benchmarked the manufacturing quality of HydraForce. For this non-standard hydraulic cartridge needle valve, AAK has 3 advantages, which are beyond the reach of most hydraulic cartridge valve manufacturers: 1.AAK adopts Japanese OKK ultra precision machine tool, and the machining accuracy of components can reach 0.01~0.3�¼m. The precision of shape and contour is 0.003 - 0.1�¼m. Its production efficiency is 30% higher, which is the cornerstone of AAK's ability to catch up the delivery. 2. AAK has been hydraulic cartridge valve ODM manufacturer of 3 world top 500 companies for 10 years. Its quality control process is more strict than the ISO certification system. We have been focusing on details and constantly optimizing technology.
