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:Add a valve on the trachea, when the valve behind the use of gas units,
Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation
Q:What does the whole copper valve mean?
Industrial oxygen pipes on the valve are all copper valve, hand wheel is not. The market had had 4 6 1 inch screw valve also has a lot of full copper. The tap also has all brass. The valve body and the inside are all copper.
Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
Q:What's the advantage of using three way valves?
Three way valve generally has a cut-off, regulation, diversion, and prevent counter flow, voltage regulation and overflow and other benefits, because of its benefits more, so the use of the three valve is extremely extensive, in the valve industry is also very important.
Q:Which direction is the valve? Which direction is it?
Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
Q:What valve is the YQZ45X-16Q?
Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
Q:What is the term "Z41H-16C" on the line?
When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
I have to answer a simple 1/2 1/4 is American Standard valve diameter to the national standard to calculate it is 1/2=DN15 1/4=DN8Also on the valve size of the meaning of the Wenzhou essence valve factory for you to answer
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 does valve A335P22 mean?
The first seems to refer to the material inside the valve, containing Cr of 13% (equivalent to the 1Cr13 of our country), FHF=full face hardThe other refers to the body of the material, the corresponding standard forWC6=ASTM A217 WC6P280GH=EN10222 P280GHA335P22=ASTM A335 P22
