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: What's the meaning of the "single valve"?
- There are nuts, plants, flush three parts. The pipeline steel or steel ingot forging molding machine fittings, connection form the socket welding and threaded, socket welding steel pipe is inserted into the socket is in welding, so called "socket joint, thread connection pipe is screwed in the screw through connection.
- 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?
- I think it's the filter. The valve unit you know, you know, or Baidu. Then contact.
- Q: the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?
- From the literal explanation, the strong counterpart connection is different from the normal connection. Valves are naturally connected to pipes or equipment, including threaded connections, flanged connections, clamp connections, welding, butterfly valves, clamp connections, etc..Strong mouth connection, similar to the butterfly valve on the clip connection, just outside of clamping method used in other valves (not seen on the clip connection with other valves), so this will depend on external interface of the valve (wafer type butterfly valve, said strong counterparts except).
- Q: Chinese valve and a valve which is better?
- These two brands are domestic big brands, as long as the quality is good, good appearance, good after-sales service on the line, as for the brand, it is a personal choice
- Q: and today the boss told me that I would like to do a valve of the commodity inspection information, and nothing else to me, which master taught meI am a professional intern, our company is doing the valve outlet, today my boss asked me to do a valve inspection data, what other data are not for me, which foreign trade master teach me ah, depressed ah ah ah???
- National commodity inspection; stainless steel products; plastic tableware; domestic porcelain; toys; wooden products; furniture; bicycles; baby carriages; shoes; clothing; lamps and lanterns; plates; household appliances; bamboo / Wood / rattan / willow / grass / banana / vine furniture etc.
- Q: What is the valve before and after the pump?
- Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.
- Q: What are the production equipment in valve shop?
- Machining equipment: CNC, universal car, milling machine, drilling machine (rocker arm drill), wire cutting, grinding machineTest equipment: valve test press according to the production of valve pressure, specifications, types of procurement.
- Q: What does valve DN50/80 mean?
- DN refers to the nominal diameter unit mm, that is, the diameter of the pipe. DN 5080 is the diameter of 50mm 80mm
- Q: What is a hot melt valve?
- The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.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: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
- The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
