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
a)Cast hole. Flange connection meet ANSI 125/150# DIN PN10/16 BS4504 PN10/16 in the meanwhile.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
d) Square and short neck. Easy to stick scutcheon and cost saving.

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 advantage of using three way valves?
- A valve can be used to turn on and off and change the flow direction of the medium.
- Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
- Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
- Q:How do you understand the valve Z41X-16?
- This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
- Q:How do you calculate the flow of the valve?
- Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
- 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:Which brand of electric valve is good?
- Electric valve does not need to use imported, domestic boutique can meet.
- Q:What should be checked before using the valve?
- The valve must be visually checked before installation1, valve opening and closing position should meet the following requirementsThe valve, the cut-off valve, throttle valve, regulating valve, butterfly valve, foot valve, the valve is in full closed positionPlug valves and ball valves should be in full open position? diaphragm valve should be in the closed position, and can not be too tight to prevent damage to the diaphragmCheck valves shall be closed and secured2, the valve shall not be damaged, missing parts, corrosion, nameplate shedding and other phenomena, and the valve body shall not be dirty3, both ends of the valve should be protected. Handle or handwheel should be flexible and light, and must not be stuck4, valve body casting, the surface should be smooth, no cracks, blisters, lock, pores, burrs and other defects; outside valve forging, the surface should be free of cracks, interlayer, double skin, scar defect
- Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
- Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
- Q:Where is the valve used?
- Generally in the pipeline above, such as the government to improve people's livelihood, engineering, factories and so on the pipeline above, Wenzhou essence valve factory
- Q:How to open the gas valve with drawings
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out.
