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:Is the valve clockwise?
The valve clockwise rotation of the handwheel is to close the valve, counter clockwise direction is to open the valve, the number above said valve opening rotating the handwheel clockwise along the colonel, to the above number 0 corresponding pointer is completely closed; in counter clockwise direction, to a maximum of 5 numbers above corresponding pointer, is the valve open to the largest degree.
Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
Said is the valve bar, adjustable valve range refers to the adjustable ratio, that is, the maximum flow control valve can be controlled with the minimum flow ratio.The regulating ratio of the regulating valve is the ratio of the maximum flow and the minimum flow that the control valve can control.
Q:What's the sewage treatment valve with?
Butterfly valve manufacturers are many, the price is also different, as long as the right can.
Q:What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
Q:What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?
This is the most widely used method of regulating flow, while protecting pumps and motors. The general classical installation method is as follows: the pump outlet is equipped with a vibration reduction joint, and then a gate valve control switch, and then install a multi-function water pump valve to adjust the flow.
Q:What does the RF of the valve mean?
The flange flange can be applied to the HG/T flange standard, or any other flange standard. HG/T will be more detailed
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..
Q:What does LBC mean in a valve?
Z: gate valve6: connection form for welding1: wedge type single gateY: the sealing surface is cemented carbide800LB: nominal pressure is 800 poundsP: the valve body is made of chrome nickel stainless steel20: nominal diameter is 20 millimetersLB refers to the nominal pressure of the valve, how many pounds, C, P refers to the body material, C refers to carbon steel, and sometimes can be omitted
Q:What valves are needed on the construction site?
Depends on the actual size of the required diameter, how much work pressure, and then choose the right valve. Commonly used PVC, cast aluminum, cast iron; PVC cheap, commonly used in small diameter pipe, cast aluminum, cast iron is relatively expensive, high pressure.
Q:How big valves are used in a DN159 pipe?
DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.
