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.

2.Main Features of the Manual Wafer Butterfly Valve

1)Flow curve tending to straight-line. Excellent regulation performance.

2)Strong wash and brush resistance and can fit to bad working condition.

3)Center plate structure, small torque of open and close.

4)Various kinds of materials, applicable to different medium.

5.FAQ

1. What is manual wafer butterfly valve?

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. What is the working principle of manual wafer butterfly valve?

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.

Q: What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?: D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.

Q: The difference between butterfly valve and gate valve: Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium. Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage.

Q: What does butterfly valve nps12cl150d373f4-150lb stand for?: NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE

Q: The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30: I suggest you find out the pressure and installation position first, the condition allows, you can choose butterfly, after all, much cheaper than butterfly valve. After the completion of the project, will be mainly engaged in the acceptance of problems, there are special management of fire units.

Q: How warm is the PTFE butterfly valve?: Ordinary PTFE clip butterfly valve normal temperature tolerance of about 120 degrees, instantly to about 150 degrees

Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?: According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!

Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer: Strokecyp3a7 gene may help identify those at.
