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 want to act as a proxy valve
As the two floor said, looking for agents depends on your targeted customer base is better sign is the price of comparative advantage of the brand. Now the valve on the market in Fujian, Wenzhou. Especially, these valves are faced with the market price, the quality of course needless to say. Maybe these valves would sell large the early recovery of funds, is also rich. But for a long time, the problem appeared, quality problems will make you sleepy fishing, I suggest you. You can't do anything sales quality and good reputation of the valve.In the few I know better. Now the best reputation is Guanlong, but the price comparative advantage or spring.
Q:What does the valve stroke mean?
The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.[1] to determine the stroke of the valve is the valve and valve two, closing stroke of its opening height, the valve opening height to diameter of the valve is fully open, 1/3, so the opening height is part size below the path + gate is closed.[2] valve: valve (Famen) is a fluid conveying system control components, with a cut-off, regulation, diversion, to prevent reverse flow, voltage regulation, shunt or overflow, pressure relief and other functions. 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:Can the gas valves be switched off regularly?
The small valve called skin stopcocks, his design is often switch, but for the sake of safety, natural gas company also installed a lock valve in front, once the leak immediately close the valve, the valve once closed to find a Gas Co came to open, so it is not necessary the case don't go off.What we usually need to pay attention to is..:1, every time you finish cooking, you must close the pipe plug valve (the valve you said).2, regular inspection of the skin tube leakage (3 months 1 can be this).3, the leather pipe and the leather pipe plug valve connected to the place has a ferrule, inspection found loose, must be tightened with a screwdriver, in case of leakage.4, the use of gas should pay attention to indoor ventilation, winter must open lampblack machine, in case of poisoning.Don't worry as long as you do the above.
Q:What is the difference between valve j941H-40 and j41H-40?
Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one
Q:Dalian hi Max Valve Co., Ltd.
I have some of them in the series of drawings.Build said veteran enterprises is the main power station valve company opened high pressure valve Wenzhou world Gansu Shenyang Nantong Shen Langao high power of Dalian is still high in alphabetical orderThe main floor is to engage in large high valve industry is a very good platform after the switch is convenient to say we all know whether peer or do
Q:Is the valve galvanized?
Butterfly valve gate, some hot-dip galvanized, and other valves are not.
Q:What does the PN on the valve mean?
1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special
Q:Pressure gauges, safety valves and other safety accessories and the cylinder can be installed between other valve components,
The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
Q:How can the valve actuators be classified?
84798990 straight stroke valve actuator84798990 angle stroke valve actuator84798990.90 all intelligent electric valve actuator84818010 valve actuator84819010 valve actuator85371090 electric valve actuatorFor the past 3 years, the shipment code, but not the same as yours, for reference
Q:What valves are needed on the construction site?
Order valve flow1, customers have special requirements for products, must provide the following instructions in the contract: a) b) the length of the structure connection form C) nominal diameter, full size, shrinkage, pipe size d) using medium and temperature and pressure range E) test, inspection standards and other requirements.2, the factory can be configured according to customer specific requirements of various driving devices.3. If the customer provides the type and model of the valve to be determined, the customer shall correctly explain the meaning and requirements of the model and sign the contract on the condition that both the supply and demand sides agree.4, futures, order customers, please call the letter in detail to tell you the required valve model, specifications, quantity and delivery time, location, factory information, billing information, delivery address.
