For ISO5211 Mounting Ball Valve connection size, most of the actuators are pneumatic, manual, electric and hydraulic operation. The following is the data sheet of flange connection size of American standard butterfly valves.  Most new ball and butterfly valves are now standard with an ISO mounting interface. This simply means that you can mount the actuator directly to the valve without a bracket and drive dog. This saves time, hassle and money. The below shows the dimensions for ISO5211.

 Butterfly valve is a kind of valve which uses round butterfly plate as the opening and closing part and rotates around the valve axis to open, close and regulate the fluid channel. It is mainly used for cutting off and throttling in the pipeline. The butterfly plate of butterfly valve is installed in the diameter direction of pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0 ° C~90 ° C; Between, rotate to 90 ° C, the valve is fully open. Butterfly valve and butterfly rod have no self-locking ability. In order to locate the butterfly plate, worm gear reducer should be installed on the valve rod. Using worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operation performance of the valve. The streamline design of the butterfly plate can reduce the loss of fluid resistance, so it is an ene...

  What do we know about industrial valves? It is a very ingenious mechanical device that is designed to either start or stop or even regulate the flow of substances such as gases, liquids, semi solid such as slurries or minerals through a pipe line or passageway. This is used in almost all industry that requires mechanical uses such as plants, infrastructures, construction, manufacturing as well as household and so forth. Most valves used in household are small in nature. It regulates the flow of either gas or water throughout the whole house. There are also valves that balances the amount of hot or cold water in your shower or tube on the other hand a bigger and stronger material are being used in those industries earlier said. The amount of substance flowing can be controlled by adjusting the controlling mechanism which can either be a plug, opening a cylinder or a wedge. The  industrial valves , on the other hand, used in plants can either be hand-operated or automatic. A s...

There are many types of industrial valves. When customers choose valves, they usually choose them according to the operating temperature, ambient temperature, pipe diameter, pipe pressure, operating pressure, interface size, medium flow, medium name, etc  Saving money always sounds like a good idea, but don’t make the mistake of cutting corners on valve installation. Choosing the ideal valve for the application on the front end may result in the selection of a costlier valve, but this investment saves savvy manufacturers from untold money and hassle down the road. When you have more than one valve to consider and each appears capable of getting the job done, the obvious selection point becomes the cost. However, there are more factors to consider before jumping at a cheaper price: Materials:  Valves need to be built to last. A cheaper model may not be constructed from the same level of reliable, long-lasting materials. Unforeseen maintenance and replacement costs could result...

  How to Identification of BSPP,BSPT, NPT threads? When you choose valves and pipe fittings , thread is a very important feature you have to consider. No matter how well the product is made, a wrong thread type will make it useless. You have to determine the thread type before you order. British Standard Pipe fittings are among the most popular of all foreign threads in the world today. These threads come in two versions: parallel (BSPP), and tapered (BSPT). The thread flank angle for both tapered and parallel British threads is 55°. Although BSP is a foreign thread, it isn’t actually metric. This is why it comes in Imperial sizes: 1/8, 1/4, 1/2, 3/4, etc. BSP parallel (BSPP) threads commonly seal via a 30° chamfer on the male thread to a 30° cone seat inside the female thread (swivel only). If it is a port application, an O-ring and washer, Elastomeric seal or a bonded washer are needed to achieve a proper seal for parallel threads. For tapered BSP threads (BSPT), a seal is accomp...
