Duckbill check valves, widely used in the demanding applications of many industries, are precision-molded, one-piece elastomeric valves that provide reliable backflow prevention at low pressure differentials. Duckbill check valves allow free flow with positive differential pressure. With negative differential pressure, backflow is checked. Pressure drop across the valve is a feature unique to duckbill check valves. They can be designed to operate in a few millimeters (inches) of water to several hundred kpa (psi), depending on valve size, geometry and compound characteristics. Duckbill check valves are also designed to start functioning at specific opening and closing pressure ranges, depending on your specifications. •normally open one-way check valves •prevents backflow leakage when minimal backpressure is applied •can be installed easily into hole and sealed by compressing flange Duckbill check valve features: Reliable backflow prevention 100% elastomeric construction eliminates maintenance Will not corrode, warp or freeze open or shut 1”-2” cracking pressure, low head loss Curved bill enhances sealing around debris Custom built for each application based on pressure and flow conditions Available in diameters from 1/2" (12mm) to 96” (2400mm) Note: 1.

Buy hydraulic cartridge check valve samples 3 times a year, and hit AAK with a big order for the fourth time 1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way. Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time. I knew that AAK had passed the investigation period of German customers. After communication, I learned that the hydraulic cartridge check valves that he purchased in Ningbo 2 years ago, were tested with 6 hydraulic valve manufacturers before and after. Either the first sample was OK, but the second one was not up to standard; Either the existing valve was tested OK, but the customized valve was abnormal. Time was wasted and delayed their equipment development. It turns out that Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent to select new hydraulic valve manufacturers. This time, they will develop a hydraulic boarding bridge, which requires non-standard hydraulic cartridge check valves. From trial order to large order, AAK has been investigated for more than 1 year. Ferdinand said that the manufacturing quality of AAK hydraulic valves, whether the ones benchmarking international brands or non-standard customized ones, had been recognized by their engineers for their functions and performance, so they decided to place large quantity order of hydraulic cartridge check valves. The reason why AAK hydraulic cartridge check valve is different from other hydraulic valve manufacturers in Ningbo is that we insist on the quality of manufacturing. 1. Not make do with the equipment. No matter CNC machining center or machine tool, only high-precision ones are selected. At the same time, the fixture is upgraded and modified by ourselves, eliminating human error. 2. Materials should be paid attention to. Different kinds of imported high carburized bearing steel should be combined with AAK's proprietary heat treatment process. The hardness of the material has gone up several steps, and its wear resistance has been improved by more than 3 times. The thermal stability and compressive strength of materials have been far ahead of other hydraulic valve manufacturers.

This morning, Robert sent an email asking about the production time of 1,200 hydraulic check valves, which surprised me a little, because in the past 2 years, he normally just placed small quantity trial orders of hydraulic check valves. Robert is a purchaser of John Finlay company in Australia. We met 2 years ago. A batch of hydraulic tamping machine equipment of their company began to receive complaints again and again from the previous year. After inspection, it was found that the hydraulic check valve in the equipment did not maintain pressure. Robert contacted the original hydraulic check valve manufacturer to find a solution. The manufacturer advised that the working pressure and working frequency of the hydraulic tamping machine may be too high, resulting in frequent collision between the ball valve and valve seat of the hydraulic check valve, affecting the sealing effect. The only solution is to replace the leaked hydraulic check valve. Although replacing the hydraulic check valve is a heavy workload, Robert has no choice but to accept. The trouble is that 6 months later, the same problem happened again. The customer was very unhappy. The boss asked Robert to find a new supplier of hydraulic check valve immediately. Robert suggested purchasing hydraulic check valves from AAK to replace those unqualified ones, because the durability test of AAK hydraulic check valves was the most lasting among all of the samples from different manufacturers at the beginning. At present, there is an equipment installed with AAK hydraulic check valve, which has been used for 1 year but without any abnormality. The boss thought that the price of AAK was more than 20% higher and unacceptable, and asked Robert to look for a new manufacturer of hydraulic check valves. In the process of continuous screening, Robert selected 5 hydraulic check valve manufacturers to try their samples. Basically, after half a year, these hydraulic check valve samples had similar problems one after another. Robert was at a loss. He once again suggested to the boss to purchase AAK hydraulic check valves. After comparing so many hydraulic check valve manufacturers, none of their samples can be used for more than 1 year under this working condition, but the equipment installed with AAK hydraulic check valve has been used for nearly 2 years, and there has been no failure to maintain pressure. If the hydraulic check valve needs to be replaced every 6 months, the after-sales cost is too high, which has far exceeded the 20% higher cost of the hydraulic check valves. More importantly, it brings the reputation of unstable equipment quality to users. After listening to Robert's analysis, the boss approved AAK as the preferred supplier of their company for hydraulic check valves. It took Robert 2 years to persuade his boss to place a large order with AAK. He knew that the durability of AAK hydraulic check valve
Last week, Eddy emailed me that after AAK hydraulic check valves of the test order has been used for 3 months , the O-ring seal was still free of wear. He was finally relieved. Eddy, who works at Terex company in the United States, has successfully purchased hydraulic valves from China over the years, and his owner is also very satisfied. At the beginning of last year, a customer complained about the hydraulic equipment supplied by their company for offshore oil field exploitation, which made him very passive. Some equipment has the phenomenon that the drilling machine rises slowly or cannot rise. Their engineer found that the hydraulic check valves used in the oil circuit of the hydraulic equipment had internal leakage, the one-way oil circuit could not be fully locked, resulting in the inability of the equipment to rise. Their engineer can only replace the hydraulic check valves with the previous spare ones and bring the problematic hydraulic check valves back to the company. Eddy sent these hydraulic check valves to the original supplier. The supplier replied that the reason for the leakage in the hydraulic check valves was that the ambient temperature was too low. The O-ring seal of the hydraulic check valves was hardened and worn quickly in extremely cold conditions, which was difficult to solve. Eddy knows that if he can't give reply to customer like this, he must find a manufacturer who is able to produce the hydraulic check valves working at low temperature. Eddy contacted several hydraulic check valve manufacturers, most of them reported that it was difficult to achieve 100% leakage free under such extremely cold conditions. Eddy was worried. When Eddy contacted us, our engineer wanted to see the real reason for the wear of the O-ring of his hydraulic check valves and asked him to send the defective hydraulic check valves. After receiving the samples, our engineer realized that even if the cold resistant O-ring is used, it may not be 100% leak free, and the structure of the sealing ring needs to be changed, because the internal structure of this hydraulic check valve is a little complex. Eddy said that this is the only different reply he received. It seems that Eddy still doesn't believe that AAK can solve the leakage problem of the hydraulic check valves. I told him that a Russian customer has purchased hydraulic relief valves from us, and their hydraulic equipment is also used in oil fields. The customer told us that under extremely cold conditions, the service life of AAK hydraulic relief valve is more than 4 times that of its peers. Three weeks later, we sent 4 pieces of hydraulic check valves of the test order to Eddy. There was no news after 3 months. Until last week, we received email from Eddy amazing that their engineers also admired our idea of adding retaining ring to the O-ring of the hydraulic check valves.
