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 "C" in D971F-16C DN450 RF mean for electric butterfly valves?
- C represents the valve body and the material is cast steel;D stands for butterfly valve; 9 stands for electric; 7 stands for clip type; 1 represents middle line butterfly valve; 16 stands for nominal pressure 1.6Mpa; RF stands for flange joint; in the form of protruding surface.
- Q: How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks
- the forked end of it will go over the spring part and the solid will work on the valve ,you can only use this one if the head is off though,the smaller ones work good if the head is still on the car,the c-clamps style though is the best one to use its safer and wont allow the springs to fly off,good luck.
- Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
- For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
- Q: What do D71, D371 and D341 represent in butterfly valves?
- D71 in D is the meaning of butterfly valve, 7 refers to the connection is the clamp, and 1 refers to the butterfly plate is the center of verticalD371 in D is the meaning of butterfly valve, 3 refers to the drive mode is the turbine, 7 refers to the connection is the clamp, and 1 refers to the butterfly plate is the center of verticalD341 in D is the meaning of butterfly valve, 3 refers to the drive is turbine, 4 refers to the connection is flange connection, and 1 refers to the butterfly plate is the center of vertical.

- Q: What is the effect of nylon coating on butterfly valve plate? Thank you
- Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
- Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
- Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
- Q: Is the pressure test of the centerline butterfly valve checked or checked?
- The pressure test of the central butterfly valve is carried out at each station.Basis：1) GB/T12238-2008 flange and clamp connection elastic seal butterfly valveRules: butterfly valve must be carried out by factory inspection and testing, inspection qualified before leaving the factory.2) CJ/T 261-2007, butterfly valves for water supply and drainageRules: each product shall be inspected by factory and quality inspection department. After inspection, the product certificate shall be attached to the factory.Butterfly: also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
- Q: What is the difference between the installation and function of a butterfly valve and butterfly valve?
- Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
- Q: What are the uses and classifications of manually operated clip butterfly valves?
- In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
