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.

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: What do the Z, J, H and D represent in the valve type?: Valve type code Z, J, L, Q, D, G, X, H, A, Y, S, respectively:Gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, pressure reducing valve and steam trapThe connecting codes for valves are 1, 2, 4, 6 and 7, respectively:1, internal thread, 2, external thread, 4, flange, 6, welding,

Q: For example, the knife gate valve, PZ73X-10C, DN50 torque is 5, torque is what role? What units?: Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.

Q: What is called protective valve, and other valves what is the difference?: Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.

Q: How to check if the gas valve is open?: The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..Chasing the answerThe valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..

Q: What do letters represent in the QF-2 and PX-32 valve models?: You check it on the national standard! One is accurate!

Q: What are the ten major brands of China's valves?: In the fluid piping system, the valve is the control element, its main function is to isolate the equipment and the piping system, regulates the flow, prevents the backflow, the adjustment and the excretion pressure. As the piping system selects the most suitable valve, it is important to understand the characteristics of the valve and the steps and the basis for selecting the valve. If you want to buy, you can choose the following aspects: 1. Select the valve according to the adjustment of medium parameters: two. According to prevent media backflow, choose the valve: three. According to the nature of the media, choose the valve. As for the brand if you can refer to the ten brands to buy China ten brands online, for example, Langao valve, a valve on the river, Amico, SF, card, open the valve on the market these are famous brands, you can refer to.

Q: What kind of valves are best used for sand drain valves?: Suzhou ATW Valve Co. Ltd production of sealing ball valve, Suzhou ATW Valve Co., according to the condition of solid particles, long-term research and in practice, and achieved good results in the condition of solid particles. You can try!

Q: Why can't the clip type check valve be directly connected with the pipe mouth or other valves?: The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
