Rotary Plug Valve A rotary plug valve with a plug-shaped flow-restricting component that follows an eccentric path as it rotates. The plug does not contact its seat until it is rotated to within a few degrees of the closed position. When the plug contacts or "cams" into the seat, the seat surfaces are dynamically aligned for closure. This rotary plug valve type may also be referred to as a rotary globe valve. How rotary plug valve work: When the material in the upper bunker falls under its own weight and fills the space in the rotor blade, it rotates with the blade to the lower outlet and is discharged. Rotary plug valve can continuously supply and discharge materials. The rotary plug valve can play the role of feeding and locking the air flow in the pneumatic conveying system. Due to the low-speed rotation of the rotor and the very small gap between the rotor and the inner cavity of the housing, the reverse flow of the air flow is effectively prevented, thereby ensuring the stability of the air pressure in the system and the normal discharge of materials. Therefor, rotary plug valve is an important part of the high-pressure gas to the material transportation in the state of the pipe network. The rotary valve is used as the unloader of the silo in the material collection system.

AAK hydraulic valve blocks adopt MB Series Plug of KVT company in Switzerland, and forms a solid sealing surface after metal extrusion in the way of expansion bite, 100% avoiding oil seepage and oil leakage of hydraulic valve block, which fundamentally solves the problem of high-pressure plugging of hydraulic valve block, and the rated pressure can be as high as 450bar without pollution. Most hydraulic valve manufacturers fail to seal the hydraulic valve block in place, but AAK has become a long-term cooperative supplier of hydraulic valve block for American customer. The vast majority of hydraulic valve manufacturers use the traditional sealing method of inner hexagonal (or outer hexagonal) screw plug and sealing combination gasket to process the hydraulic valve block. The service pressure is basically in the range of 50-300bar, and the operation is simple and easy to disassemble. The hidden danger is that there are requirements for tightening torque. If the torque is not reached, it is easy to leak, and if it exceeds, the thread is easy to be damaged, some hydraulic valve manufacturers even apply anaerobic glue on the thread, which is easy to cause particles of anaerobic glue to fall into the hole, resulting in oil pollution or valve jamming of the hydraulic valve. In addition to the function of hydraulic logic control, some hydraulic valve blocks also need to work for a long time in the environment of high-pressure, high-frequency pressure impact and temperature impact. Therefore, the sealing process of hydraulic valve blocks is very important. Declan, an American customer, is a hydraulic friend of Blake. He recently encountered trouble in purchasing the hydraulic valve block. The approval sample of the hydraulic valve block provided by the original factory showed that the parameters were completely normal in the first test, and there was slight oil seepage in the second test. Declan thought it was something wrong with the hydraulic system. Declan checked and tested the samples for the third time, the hydraulic valve block began to leak oil. After communicated with the original manufacturer, Declan was advised that this sealing process is common in the industry, he should either accept the hydraulic valve block as is or cancel the order. Declan consulted more than 30 hydraulic valve manufacturers through B2B, Google and other websites. Their hydraulic valve blocks all adopt the general sealing process in the industry, and can not guarantee 100% sealing. After consulting Blake, Blake suggested him contacting AAK and told him that AAK hydraulic valves are not market goods and have some their own R & D processes. Perhaps AAK does not adopt the general sealing process in the industry for the sealing of hydraulic valve blocks. According to the hydraulic valve block drawings from Declan, we sent out the hydraulic valve block samples a week later.
The pressure in the pine line push the seat ring moving towards ball, thus form the sealing; as the sealing is formed by the line pressure itself, the performance will be better, in the mean time, it also reduced the operation torque of the actuator; while the ball cavity pressure exceed the line pressure, the pressure difference will push the seat off the ball to release the excessive pressure to the pipe pine; when the temperature rises, it wont cause abnormal pressure rise in the valve cavity. The pressure can be released to zero when the valve is in full close, full open or under pipe line pressure; also, the seeper, dirt or deposit can also be eliminated by removing the drainage plug on the valve body In case the sealing element is destroyed by eye winker in the pipe line or smashing, sealant will be used to avoid leakage; the stem is designed with two part sealing, and sealant can be injected between. ven when the seal is burned down by fire, the metal to metal seal design will be applied to avoid spread of fire. Body to use high quality forged steel, with welding on the mid body, formed one piece; appearance design, high strength, light in weight, smart in volume; bolts and nuts are not adopted, thus no leakage point; suitable for under ground application. he ball is supported by upper stem and the lower trunnion; the ball axle is maintained in its centerline, thus is good in sealing and operation; the low friction TFE in the stem and trunnion part enables the valve to operate smoothly and simply under pressure. The ball valve series is maintenance free, thus greatly reduced userí»s cost; the bearing, seal are adopt low friction co efficiency material, no lubricate is required

Smith is the head purchasing of a hydraulic company from California. His purchasing of hydraulic valves in recent years has been smooth. In the last hydraulic valve block order, the parameters were normal when the hydraulic valve block approval sample was tested for the first time, but there was oil leakage in the second test on the hydraulic valve block. After rechecking, the oil leaked again in the third test on the hydraulic valve block. Smith communicated with the hydraulic valve block manufacturer for many times but without results. The manufacturer said that this is the traditional sealing process of hydraulic valve block, Smith should either accept it as is or cancel the order. Smith knew that the delivery date confirmed with the customer was due in 1 month, so it was urgent to find a new hydraulic valve block manufacturer to replace the current one. Smith checked the sealing process of no less than 20 hydraulic valve block manufacturers. They all adopted the traditional sealing method of hexagonal plug combined with and sealing gasket. Smith knew that although this sealing method is simple to operate, it has very high requirements for tightening torque. When the torque parameters are not up to standard, the hydraulic valve block is easy to leak. In order to prevent leakage, some hydraulic valve block manufacturers apply anaerobic glue on the threads. During operation, the particles of anaerobic glue fall into the valve hole, causing oil pollution or valve jamming of the hydraulic valve block. The delivery date is approaching day by day, but the new qualified hydraulic valve block manufacturer has not been found yet. Smith is worried and asks around. His friend Caleb gave him the contact information of AAK hydraulic valve. Caleb is also our hydraulic valve customer in the United States. He suggested Smith contact AAK, and told him that AAK hydraulic valve exports to European and American markets all year round and has some unique R & D processes. Perhaps AAK will be different in the sealing treatment process of hydraulic valve block. Smith directly sent us the hydraulic valve block drawing and required that the traditional sealing technology should not be used. A week later, AAK sent the hydraulic valve block sample successfully. Two weeks later, Smith informed AAK by email that the parameters of AAK hydraulic valve block were fully up to standard after 3 tests, and there was still no leakage after the 4th and 5th tests. Smith is very curious about how the sealing process of AAK hydraulic valve block is different from that of other hydraulic valve manufacturers? The vast majority of hydraulic valve manufacturers fail to seal the hydraulic valve block in place because they stick to the rules in technology. 6 years ago, AAK was eliminated by the customer due to the leakage of the traditional sealing technology of the hydraulic valve block. After that, we deci

What is Globe Control Valve A globe control valve is a type of control valve that is designed to regulate or control the flow of fluid through a pipeline. It consists of a movable disk or plug, which is positioned in the flow path and can be moved by an actuator to regulate the flow of fluid. The valve body typically has a spherical shape, hence the name "globe valve." The globe valve can be used to control the flow rate, pressure, and temperature of a fluid. It is commonly used in applications such as process control, oil and gas refining, power generation, and water treatment. The valve can be operated manually, electrically, or pneumatically, depending on the application requirements. Globe valves are known for their precise flow control and low-pressure drop, making them an ideal choice for applications that require high accuracy and performance. They can also be used in harsh environments and can withstand high temperatures and pressures.
