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:The valve is rusty and can not be opened. What shall I do?
There are pictures, for different valves, then choose different ways of opening.
Q:The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop. Thank you, sir!
The blue one is the separate body, and the red one is the welded flange on the pipe. There is rubber on the valve body, and it can be sealed with flange. This is determined by the structure of the butterfly valve, usually DN150 of the small diameter butterfly valve are installed this way. It comes with flanges, but the prices are much higher. Small caliber general butterfly valve is generally used for low pressure, leakage requirements are not high, so rarely use its own flange. With flanges, it is generally used in petrochemical systems and has a much higher pressure level.
Q:How to check if the gas valve is open?
The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..Chasing the answerThe valve handle and pipe as "one" word proved to come, as "ten" word is off.

Q:How to better maintain the valve?
We should keep the valve cleanWe should regularly check and maintain the integrity of the valve the other components. As a fixed hand wheel nut fell off, to be filled and can not manage, otherwise it will grind the valve stem upper garden square, gradually lost with the reliability, and even can not startWe do not rely on the valve support other heavy objects, do not stand in the valveThe stem, especially the threaded part, to regular cleaning, the dust has been soiled should be replaced with a new lubricant, because the dust contains hard debris, easy to wear thread and stem surface, affect the service life
Q:How do you understand the valve Z41X-16?
This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
Q:Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
Hardware city inside, on the opposite side of the East Second Ring Guoqiang steel market
Q:Which direction is the valve? Which direction is it?
And we usually drink mineral water, drink bottles are in the same order
Q:What are the main equipments for valve production?
I know these gate valves, globe valves, plug valves, ball valves, butterfly valves, needle valves, diaphragm valves, check valves, and throttle valves
Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
You really want to go to the big water to fix the valve and be prepared for the follow-up, just in case
Q:What does "1/2" mean on the valve?
1/2 on the valve indicates that the ends of the valve are 1/2 inches in diameter.Valve 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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
