How do you install a wafer style valve?
How to install wafer type butterfly valve
- Place the wafer-type butterfly valve between the pre-installed two-piece butterfly valve flanges.
- Insert the bolt and nut into the flange hole to connect the valve body with the flange.
- 3, welding the flange on the pipe, this step to use spot welding.
What is wafer type connection?
In a wafer connection the valve is installed between the pipe flanges and tightened to its place with the bolts for the pipe flanges. Wafer type body is the lightest body version for mounting between piping flanges. Therefore a wafer valve use to be cheaper than other valves.
What is difference between butterfly and wafer lug?
Lug type valve as the name suggests has lugs that are used to mount the valve to lugs that are attached the flanges on then ends of sections of pipe so that each length of pipe can be removed and replaced independently. Wafer type valves don’t have attachment lugs, though them may have alignment lugs.
How to install and maintain a wafer butterfly valve?
WAFER BUTTERFLY VALVE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS INSTALLATION 1) Thoroughly clean and prepare the piping system before valve installation. 2) Inspect the valve port and seating surfaces for cleanliness just prior to installation. 3) Support the valve to prevent unnecessary stresses induced by connecting pipe.
Where does the butterfly valve go in a pipeline?
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of the wafer butterfly valve is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
How are flanges attached to a butterfly valve?
When the pipe is installed on the pipe, two flanges are needed to clamp the butterfly valve first, and then the flange is connected with the flange on the pipe. Corresponding to the butterfly valve is another connection, flanged.
Which is the best type of butterfly valve?
The structure principle of butterfly valve is especially suitable for making large diameter valve. This kind of valve should be installed horizontally in the pipeline. There are two kinds of butterfly valves in common use: wafer butterfly valve and flange type butterfly valve.
