At present, the flange centerline butterfly valves produced by valve manufacturers are generally made of ball milled cast iron, cast steel, 304 stainless steel, etc.! There are many kinds of materials, and the butterfly valve is mainly used for sealing, because although this butterfly valve has water and oil gas, it needs other media to be used, but we also need to choose the sealing material according to different conditions! Rubber is often used, both of which are available.
This valve is often used as an on-off valve, and some can also be used to properly adjust the flow rate. In addition, the flange centerline butterfly valve can be equipped with a handle and a turbine, and after adding a pneumatic or electric actuator, it can also achieve industrial braking. It is a valve with high cost performance.
Butterfly valve consists of three parts: valve body, valve plate and seal. During operation, the valve plate rotates 0-90 degrees at the axis. This is the angle between the valve plate and the valve body will become smaller and smaller, and it will slowly contact our gasket, and the subsequent valve plate will squeeze Our sealing surface will stop at the highest point of extrusion at 0 degrees. This time is the best sealing time! The front pressure can be completely sealed.
The shaft plate has no needle connection, compact structure, flange connection, and easy installation.
90° opening and closing, worm gear transmission, low operating torque.
Two-way sealing, with good mechanical properties, superior processing performance of two-position two-way solenoid valve.
The flow characteristics tend to be flat and have good adjustment performance.
Sealing materials available for users to choose.
The valve can be used as an exhaust valve at the end of the pipeline, with reliable performance.
The valve seat and body are all organic structures, which can extend the service life of the two-position two-way solenoid valve.
Flange centerline butterfly valves are usually not used in high or strict occasions! It is not that the two-position five-way solenoid valve is not good, but some users specify other valves or they are not used on site! The principle and characteristics of this valve are also to let users understand the actual situation of using flange centerline butterfly valves, and they also have general judgments to make their pipelines and equipment safer!
