Description
EMT Common Type Pig Signaller
EMT Pig Signallers are necessary equipment in the pigging process of long-distance pipelines. It can accurately show whether the pig passes a predetermined point successfully. Besides, it also assists in the smooth completion of the pigging line.

Removable Pig Indicator On A Flange Valve
This kind of pig is removable under pressure. A Flange valve is a kind of valve. Its closing part is a sphere. Through the sphere around the center line of the valve body, it achieves opening and closing. This valve is mainly used to cut off, distribute, and change the flow direction of the medium in the pipeline.

Removable Pig Indicator with an Isolation Valve
There is an isolation valve on the base of the removable pig indicator. The way to connect is also a welding connection. An isolation valve is a valve in fluid handling systems. The valve works to stop the flow of process media to a given location, usually for maintenance or safety purposes.

Removable Pig Indicator with a DBB Valve
Except for the isolation valve, we also offer DBB valves. At its core lies the clever operation of the two sealing sliders on the cock. DBB valves achieve efficient, low-maintenance sealing performance. Through a precision rail structure, it provides both easy service access and additional security

Non-intrusive Pig Indicator
Different from intrusive pig signallers, it is a non-intrusive type. That is to say, you do not need to put it in the pipe. Just tying it on the outer wall of the pipe is ok. Because of this feature, it is more convenient to operate. Therefore, if you do not want to punch on the pipe, choose this kind of Pig Signaller. The advantages of a flanged ball valve include small fluid resistance, simple structure, small size, light weight and easy operation
