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
a)Cast hole. Flange connection meet ANSI 125/150# DIN PN10/16 BS4504 PN10/16 in the meanwhile.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
d) Square and short neck. Easy to stick scutcheon and cost saving.

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 to suppress the valve?
- Upstairs is right... But look at the situation, there are some valve flange is 16 pressure, but the body can only play 10 pressure, there are cases.. Such as knives, valves and other ventilation valve
- Q: What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?
- Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.
- 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: Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.
- FV: flow control valveLV: level control valveCV: flow coefficient flow coefficient CvFlow coefficient of an imperial unit. Is equal to the temperature of 40 degrees Fahrenheit Fahrenheit water in -100 1psi (6894.8Pa) 1min flows through the valve pressure drop US gallonThe domestic habits called Kv, Kv said that the valve flow capacity, it is defined as: when the control valve fully open, the valve pressure difference at both ends of a P 100KPa, R 1gf/cm3 (severe fluid that is often warm), per hour through the number of flow control valves, with m3/h or t/h.Cv=1.167Kv
- Q: What does "DN15" mean? What does "PN 16" mean?
- Valve nominal diameter 15mm, valve nominal pressure 1.6MPa
- Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This is the same as the second, pull out half or all, so that you can use gas, ha ha!
- Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?
- You want to ask the classification or valve DN254 mean?. The data you gave was incomplete. No answer.
- Q: I would like to ask commonly used water valve what kind of? What are the characteristics?
- Valve is used as cut-off media, the flow through the fully open, then the pressure medium to run minimal loss. Usually does not require frequent valve for opening and closing, and maintain the gate fully open or fully closed condition. Not suitable for use as a regulator or throttle. For high-speed flow of medium, the gate conditions can cause vibration of the gate in the partial opening, and the vibration may damage gate and valve seat sealing surface, and the throttle gate will suffer erosion media. From the structural form, the main difference is that the sealing elements form. According to the form of seals, often divided into several different types of valve, such as: wedge gate valves parallel gate valve, parallel gate valve, wedge gate valve. The most commonly used form of wedge gate valve and parallel valve
- Q: How does the valve open?
- Now the valve is in a closed state, the general valve on the valve flow direction marked, like you figure on this, flat side perpendicular to the flow channel is closed, parallel to the flow channel is open.
- Q: Name: valve actuatorFunction: control valve switch by controlling air flow sizeIntended classification commodity code: 8412310090 (other linear acting pneumatic power unit, pressure cylinder)Shanghai Pudong Airport customs change classification: 84123900 (other pneumatic power unit)Commodity code information given by China Customs official network: 8412310090 (actuator, valve parts, valve actuation, pneumatic)Our goods encoding 8412310090 is classified to the Shanghai Pudong Airport customs dismissed, there are no friends of this commodity encoding on the official website of the detailed specifications defined, I Secretary in accordance with the valve function into 8412310090 encoding. Thank you
- The boring actuator, that is, the pneumatic valve actuator, is described in the customs notesPneumatic valve actuator (three) separately presented. This device is equipped with a piston metal enclosure, linear motion of compressed gas generated by a needle perpendicular to the piston rod into the rotary motion, in order to control plug valve or other device with a rotary deviceSo the Shanghai customs will bring you the list backIn fact, the most important point of distinction or the actuator is pneumatic energy conversion in what form movement of the mechanical energy output, if it is a straight reciprocating, 84123100 is correct, if not belonging to the rotary linear motion, or radians, 841239 correct
