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 does the "XV" valve mean?: XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.

Q: Is the valve clockwise?: Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.

Q: What is the difference between the valve before the pump and the valve after the pump?: Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.

Q: What's the difference between valves and valves without valves?: The difference between a valve with and without a valve is that it has the advantage of having the valve exhaust. The advantage of the valve is that it can control the amount of exhaust and prevent the discharge of other fluids.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?: The valve wall thickness is the standard valve check directly in the relevant standard, for insert grade valves need to use interpolation method to calculate the valve wall thickness, actually don't need what difficult to complete in EXCEL software.

Q: Is the filter also valve?: Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category

Q: What is a heavy body valve?: Heavy body valves are heavy duty valves. This is the size of the valve, weight, wall thickness are linked, in general, the gate valve and cut-off valve is divided into heavy, medium and light three, other valves are not so distinguished.

Q: How much is the 150LB of the valve?: The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..

Q: What is the BV valve?: It should be American Copeland company, BV series valves;

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!
