 1. Manual Wafer Butterfly Valve Description

Butterfly valve is mainly consisted of body, stem, disc, seat and driver(lever, gearbox, pneumatic and electric Actuator) and so on. On off and controlling flow of valve are made by turning stem and disc together.A butterfly valve is a valve which can be used for isolating or regulating flow.

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. 

2.Main Features of the Manual Wafer Butterfly Valve 

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

 

2)Small in size and light in weight and maintaince.
It can be mounted whereever needed.

3)Simple, compact structure, quick 90 degree on-off operation.

4)Disc has two-way bearing, perfect seal, without leakage under
the pressure test.

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

 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. 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:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
Q:Butterfly valve model D373F-16C, ask God answers
D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel
Q:Check valve; flexible joint `; installation order of electric butterfly valve
Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
Q:What type of butterfly valves do you have in DN125?
The butterfly type according to the usage, and there are many kinds of driving modes, different means, generally expressed as follows: Butterfly symbol: D; 1, drive mode: 0: 1: electromagnetic solenoid valve; hydraulic; electro hydraulic; 2: 3: 4: worm gear; spur gear 5: bevel gear;; pneumatic; 6: 7: 8: gas - Hydraulic; hydraulic; 9: Electric; handle, handwheel: no code. Connection: 2, valve is generally only two, 4: 7: flange type; clamp; 3, butterfly valve structure code: divided into sealed and non sealed type two; seal type: 0: 1: single eccentric; vertical center; 2: 3: three double eccentricity; eccentricity; 4: linkage; sealing type: 5: 6: single eccentric; vertical center; 7: 8: three double eccentricity; eccentricity; linkage mechanism: 9. 4, the sealing material: This lot, watch some kinds of H:Cr13 stainless steel; lining; J: S: X: plastic; rubber; for example: D971X: refers to the electric clamp center vertical plate rubber sealing butterfly valve.
Q:What are the butterfly valves models?
Divided by connection:1 pairs of clip butterfly valveThe butterfly plate of the clip butterfly valve is installed in the direction of the diameter of the pipe. The valve is fully open.The clip butterfly valve is simple in structure, small in size and light in weight. Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.2, flange butterfly valveThe flange butterfly valve is a vertical plate structure, and the stem is a sealing ring of an integral metal hard sealing valveFor flexible graphite plate and stainless steel plate composite structure, mounted on the valve body, butterfly plate sealing surface of stainless steel surfacing. The sealing ring of the soft sealing valve is made of nitrile rubber and is mounted on the butterfly plate.3, lug butterfly valve4 、 welded butterfly valveWelding type butterfly valve is a non sealed butterfly valve, widely used in medium temperature less than building materials, metallurgy and mining, electric power production process at 300 nominal pressure 0.1Mpa pipe, used to open and close connected, or adjust the medium quality.
Q:Gate valve, butterfly valve and so on can do the valve so that?
Do a lot of use valve and butterfly valve, pneumatic / hydraulic, or electric device, automatic control valve, adjust its switch angle, so as to achieve the purpose of regulation. For example, in the factory, in order to ensure the top pressure, then the pressure regulating valve, the valve is automatically adjusted by a butterfly valve! And there is also pressure regulator, pressure regulator valve series is used independently. Of course the more, is mainly used to adjust the flow!
Q:i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II
well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..
Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.
Q:Butterfly valve common faults and treatment methods?
Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.
