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: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother
- Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on
- Q: What is the difference between valve j941H-40 and j41H-40?
- I see "valve design manual" category code table, in front of 9 of the electric drive, no 9 is the ordinary hand wheel drive.
- Q: Which industries need valves?
- 3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).
- Q: What does the 4 point valve mean?
- Commonly used valves, pipes in the 4 points, 6 points, an inch, is the earliest use of the length of the British unit, metric units are 15, 20, 25 mm, and now people are also used to call 4 points, 6 points, an inch.1 inches =25.4 mm1 feet =12 inches1 inches =8 cents
- Q: In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?
- Common valve position is few, 1 or 2 wash basin faucet pipe toilet pool 3 4 water heater 5 water washing machineThese positions require only simple ball valves or globe valves. Gas valves need not be considered, provided by gas installation companies (specific standards).The main valve can achieve the above water source control, the installation of the branch valve is to take into account the maintenance is convenient, does not affect other water.
- Q: What are the major brands of valves abroad?
- I say a few familiar: Tyco (the world's largest manufacturer of valves, the valve can provide almost all of it) Fuchs (a bit like, with the whole series of Tyco products)Blake (mainly butterfly valve, ball valve, chemical and water treatment applications up)Gaemi (diaphragm valve is doing very well) KSB (mainly in the power industry valve, globe valve, etc.)
- Q: What kind of valves are best used for sand drain valves?
- Suzhou ATW Valve Co. Ltd production of sealing ball valve, Suzhou ATW Valve Co., according to the condition of solid particles, long-term research and in practice, and achieved good results in the condition of solid particles. You can try!
- Q: What are the general types of valves?
- Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve
