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:Air compressor out of the gas with what kind of valve control okay, globe valve or other?
If the factory uses, it is recommended stainless steel ball valve
Q:What is the difference between the valve before the pump and the valve after the pump?
Before the pump few valves, up to a foot valve, pump valves, convenient maintenance, then the most important is that the action of check valve backflow, water hammer....
Q:How does the valve rust die?
The treatment of valve rust is as follows:1, use corner grinder cut off valve, and then a small mill grinding wheel cutting residual film cut pipe installed in the screw part, when the attention of cutting depth.2, with the amount of hydrochloric acid corrosion and rust of the valve, until the rust completely removed, rinse with water.3, on the newly purchased valve galvanized, can effectively prevent rust.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:Remove the handle and lever the stem rotation with a wrench,
Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34
Q:Where is the Shandong valve? How about joint valves in Shandong?
Zigong Sichuan power station valve factory is a professional power equipment supporting valve factory, mainly power plant high temperature and high pressure valve, plug valve, ball valve, temperature reduction and pressure relief device
Q:What does the ZH41 valve ZH41 mean, and what other specifications?
Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
Q:What is the flow medium of the valve?
What is the valve. If the water through the valve, the medium is water. I hope I can help you.
Q:What are the technical requirements of valves, such as "Z15W-25T"?
The first Z represents the gate valve;The second bit is omitted, indicating the handle or handwheel;Third bit 1, indicating internal thread connection;Fourth bit 5, indicating dark wedge rigid single gate;Fifth W, which means the sealing materials are the main body material of the valve;The second paragraphThe first 25, said the nominal pressure is 2.5MPa (valve used in accordance with the pressure level of GB/ 1048, the use of GB/T 1048 standard 10 times the unit of MPa (MPa) value, otherwise the unit value is MPa. If it is a power station valve, the unit value is MPa.)Second bit T indicating copper and copper alloy for the valve body.
Q:The valve is rusty and can not be opened. What shall I do?
Spray with rust removing agent on the rusty rotating parts of the valve. Then use an afterburner to make a tentative rotation. Open it and turn it in the opposite direction. And then spray rust remover. Repeat this several times, and the valve will probably open. Seriously rusty valve, if it really can not open, simply replace it.
