What is a (CI) Butterfly (BF) Valve?

A CI butterfly valve is a control valve which can be used to isolate or regulate. The valve operates with a disc fixed through a stem in the body of the valve.

Operation of a CI butterfly (BF) valve:

Butterfly valves, like any other control valves uses an obstruction component.. In this type of valve, a disc is used which is operate with a lever, gear, or actuator on top. This disc is attached to the upper control with a stem which goes from the center of the disc. Butterfly valves some time uses ring gaskets of softer material to provide leak proof operation.

Benefits of using a CI Butterfly (BF) Valves:

Butterfly valves are compact as compared other types of control valves or mechanical valves.  Its compact size makes it very easy to install as well. One of the key benefit of using this type of valve is its affect on the pressure. As the disc when opened sits perpendicular on the valve seat and the disc being slim cuts between the media hence not reducing the pressure in the pipeline.

What is the meaning of wafer type double flange PN10?

Wafer type is a compact design terminology. In other words wafer type valve is sandwiched between 2 flanges in order to install it on the pipeline. This particular valve comes with 2 flanges welded on the ends of the butterfly valve. In order to install the valve, 2 flanges have to be welded on the pipe and the valve is screwed along the holes present on the flanges. The working pressure rating of the valve is 10 kgs /sq cm. Beyond which the valve is not suitable to operate. Check out our range of butterfly valves here! For more information check here
