1. Manual Wafer Butterfly Valve Description

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

5.FAQ

 

1. What is manual wafer butterfly valve?

A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.

 

2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

3. What is the working principle of manual wafer butterfly valve?

 A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

Q:How to use current to control valve opening and closing?
Switching type (one on and off)Block digital display with the upper and lower limit control valve opening and closing is goodProbably more than 100Regulating type (to keep temperature at a constant value)With PID valve position regulator can be very good controlAbout 300 more
Q:How about the quality of FITOK valves?
The United States fitok valve is the main valve and needle valve, globe valve instrument and meter tube also do.The quality of foreign valves are still good. Everyone thinks French valves are better than American ones. But the price is not cheap
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective. Butterfly valve manufacturers are many, the price is also different, as long as the right can.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Can be universal,Material is the same, the fuse will not cause shrinkage when you can use
Q:What valve should be used to test the water valve?
Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
Q:What is the difference between a stop valve (a power station valve) and other valves?
High pressure, special material, complex structure, seldom manual operation.
Q:What should be checked before using the valve?
The valve must be tested before installationI. examination of documentsThe valve must check the quality documents before installation, the valve manufacturer should be nameplate, nameplate and the body should be the name of the manufacturer, valve type, nominal pressure, nominal diameter and logo, must comply with the "universal valve logo" GB 12220.Two, appearance inspection
Q:Is the valve clockwise?
The valve that can rotate is the principle of screw and nut. We can see that the switch is also buckled, so it is counterclockwise, the net is rotated out, clockwise downward, so it is off.
Q:What are the major brands of valves abroad?
Fisher (Emerson's brand, pneumatic head and regulating valve is good) mountain Wu (Japan's control valve is doing well)
