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: 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: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?
- From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)
- Q: How about leaking water pipe valve?
- 1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
- Q: What is the valve?
- Is the switch, switch on the pipeline and can walk on water, air, oil and so on go. A lot of categories, you can control the on-off, control pressure safety valve, as well as a lot of filtering valves.
- Q: The expert can tell me how to install this valve, and what fittings to use on both sides
- It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding
- 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 technical requirements of valves, such as "Z15W-25T"?
- Z = gate valve1 = internal thread connection5 = dark rod type (structural form)W = body seal payments25 = 2.5MPa (nominal pressure)T = copper (body material)Landlord can refer to JB/T 308-2004 valve model preparation methods
- Q: What valve is the YQZ45X-16Q?
- Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
- Q: What are the ten major brands of China's valves?
- 1. fine fine group valve Co., Ltd.2. Zhuzhou Southern valve Limited by Share Ltd3 Chinese KaiWeiXi valve group4 the Sufa technology industry Limited by Share Ltd5 Zhejiang Chaoda valve Limited by Share Ltd6. Sichuan Zigong high pressure valve Limited by Share Ltd7. 、 Shanghai Valve Manufacturing Co., Ltd.8.

- 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
- Various types of valves, with the continuous improvement of various types of equipment, process, the types of valves are still increasing. But generally speaking, they can be divided into two major groups.(1) automatic valve. A valve that moves by itself depending on the capacity of a medium (liquid, air, steam, etc.). Such as safety valve, pressure reducing valve, check valve, steam trap, air trap, emergency shut-off valve and so on. (2) drive valve. A valve operated by hand, power, hydraulic, or pneumatic. Such as gate valve, globe valve, throttle valve, regulating valve, butterfly valve, ball valve, plug valve and so on.
