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.
The flange connection size of American standard butterfly valve is ISO5211. American standard butterfly valve does not need to be explained. It is that the butterfly valve produced by American standard is called American standard butterfly valve. What is the upper flange? It refers to the size of the connecting part of the valve body and actuator. We call the upper flange size. The standard referred to is ISO 5211 international standard.
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.
Type is the code of the upper flange. In daily communication, we usually use codes like F07 and F10 to represent the connection size
D1 is the outer diameter of the upper flange
D2 is the diameter of the groove on the upper flange. Usually some actuators have a boss, a groove, and a convex groove to start and fix
D3 is the drilling center of the upper flange
D4 is the specification of bolt. Generally, the upper flange of American standard butterfly valve adopts the form of through hole
H1 is the depth of the groove
H2 is generally negligible
The last item is the number of holes
In order to connect the actuator and American standard butterfly valve, in addition to the above dimensions, there are stem dimensions, which can be square centered, round rod with keyway, and the height of the stem exposed from the bracket. With these dimensions, it is the completed dimension, so as to ensure the connection between the actuator and American standard butterfly valve.
