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.

2.Main Features of the Manual Wafer Butterfly Valve

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:How does the valve open?: Turn the valve counterclockwise, turn clockwise, or turn left, right and leftYou turn the valve to the left.

Q:How do you calculate the flow of the valve?: Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.

Q:Who knows which kind of water valve is good?: Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.

Q:How about the valve?: Now, there is an office in Beijing, valve enterprises in the valve, a lot of online ah, you click to see if you want information

Q:Z11H/Y forged steel gate valves H/Y what does that mean?SZ45H S what do you mean?Blow 2Z41YGY-40P, what do you think?What does NKZ61H vacuum valve NK mean?What does DS/Z64H water seal valve DS mean?Specific valve number how to see ah, detailed information, thank you!: The meaning of valve number:Valve type Z, J, L, Q, D, G, X, H, A, Y and S respectively: gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, relief valve, drain valve.The connecting codes for valves are 1, 2, 4, 6, 7, respectively: internal thread, 2, outer thread, 4, flange, 6, welding, 7, pair.Valve transmission mode code 9, 6, 3, respectively, said: 9, electric, 6, pneumatic, 3, turbo worm.Body material Z, K, code Q, T, C, P, R and V respectively: grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steel.Seat sealing or lining R, T, X code, S, N, F, H, Y, J, M, W respectively: austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material.

Q:Is there any difference between the valve and the water valve?: It doesn't make any difference. The valve can pass through the water or the oil

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:the valve to an electrical signal, with this signal to control other components, ask: what valve?: Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation

Q:What valve should be used to test the water valve?: 1, ball valve.2, the water test valve can be ball valve, gate valve, stop valve, installed in the fire sprinkler system at each level of the end of the pipe.

Q:Valve difference: That depends on where it is used! No one knows how many kinds of valves. If you have water, you can use gas, food, and so on.
