Difference Between Flanged Butterfly Valve and Wafer Butterfly Valve

Butterfly valves are widely used in petroleum, gas, chemical, water treatment and other general industries. According to the different connection methods, butterfly valves can be divided into wafer butterfly valves and flanged butterfly valves, however, what is the difference between these two different connection methods of butterfly valves? Today’s article will introduce the difference between flange butterfly valve and wafer butterfly valve.

What is flange butterfly valve?

Flange butterfly valve is a universal fluid control valve, flange butterfly valve has the function of regulating flow, controlling pressure and changing flow direction. It consists of valve body, valve plate, valve seat, valve shaft, butterfly plate, bolt, nut and so on. The valve plate in the valve body can be rotated to change the position of the butterfly plate, thus changing the flow rate. It can be used for regulating flow, controlling pressure and changing flow direction, and is a very commonly used fluid control valve.

What is wafer butterfly Valve?

Wafer butterfly valve is a kind of valve to control the flow, the wafer butterfly valve consists of a round butterfly plate and a fixed ring, the butterfly plate can be rotated in the ring, so as to control the flow of fluid. Wafer butterfly valves can be used to control the flow in pipelines, such as drainage, cooling water and lubricating oil.

Difference between flange butterfly valve and wafer butterfly valve

Connection method

The most obvious difference between flange butterfly valves and wafer butterfly valves is the difference in connection method. The flange butterfly valve is connected together by bolts and sealed by gaskets between the flanges, while the wafer butterfly valve clamps the wafer flanges on the pipeline through the clamping force of the butt-clamp flanges, and then seals the flanges through the gaskets.

Installation method

Flange butterfly valves are generally installed by flange connection, by setting up separate flange connection on the pipeline; while wafer butterfly valves are installed by butt-clamping the butt-clamping flange on the pipeline.

Structural differences

Wafer butterfly valve with longer bolts, and no flange itself, so generally do not install at the end of the pipeline and downstream need to dismantle the position, because in the dismantling of the downstream flange, the clamped valve will fall, so that the valve at both ends of the pipeline can not work properly; and flange butterfly valve does not have such a problem, the flange body has a flange, and the pipeline with flange pairing with a bolt connection, the nut locking, so that when one end is removed, the valve is connected to the pipeline by a bolt connection, and the nut locking. So when one end is removed, it will not affect the operation of the other end.

Price difference

Wafer butterfly valve is cheaper compared to flange butterfly valve. There is no flange at both ends of the body of the wafer butterfly valve, only a few pilot bolt holes, and the valve is connected to the end flange with a set of bolts/nuts. In contrast, it is easier to disassemble and the valve is cheaper, but the disadvantage is that if one sealing surface is out of order, both sealing surfaces have to be disassembled. Flanged butterfly valve valve body flange at each end, and pipe flange connection. Sealing is relatively more reliable, but the valve cost is higher.

Conclusion

Flanged butterfly valves and wafer butterfly valves are both important valves for pipeline fluid control, and are the key products of DELCO Valve.
