1. Manual Wafer Butterfly Valve Description：

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.A butterfly valve is a valve which can be used for isolating or regulating flow.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

1.Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
2. Excellent sealing performance with no leakage. Long service life.

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:What is the medium flow rate when the centerline butterfly valve is fully open?: On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.

Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?: High performance materials have a lot of outstanding advantages: such as low water absorption, corrosion resistance, insulation, cold insulation performance, etc., is 4 times the ordinary material butterfly valve.Anti condensation butterfly valve body adopts ultra light aluminum alloy valve body, its weight is only 1/3 of the traditional butterfly valve, the torque is small, the use and installation is convenient, and the corrosion is avoided.

Q:What kind of butterfly valve is sd342x?: Sd342x: two-way double eccentric soft sealing butterfly valveS: two way pressureD: butterfly valve3: turbine operation4: flange connection2: double eccentricX: rubber sealProbably the shape is not so good in appearance,Double eccentric mostly elastic sealThree eccentric is multi-layer sealHope to be of help to youOpened valve Co., Ltd. on the production of butterfly valve

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:What do D71, D371 and D341 represent in butterfly valves?: D71 stands for middle line to clip butterfly valveD371 represents the worm wheel centerline pair clip butterfly valveD341 stands for worm gear flange butterfly valve

Q:My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.: The EGR valve is there to reduce nitrous oxide emissions and lower the temp of the combustion charge. This has the affect of reducing the octane requirement of the engine. This isn't a bad thing. When the valve hangs open, the thing will run bad at idle and could even die. The thing is, the valve could be perfectly fine and the sensor could be bad. Since some states won't give you a sticker if the light is on, you're probably stuck with replacement.

Q:Classification of telescopic butterfly valve: (2) temperature butterfly valve. 120 C<t<450 C butterfly valve(3) normal temperature butterfly valve. One 40C<t<; 120 C butterfly valve(4) low temperature butterfly valve. One 100<t< one, 40 C butterfly valves(E) ultra low temperature butterfly valve. T< one, 100 C butterfly valve (1) clip butterfly valve(2) flanged butterfly valve(3) lug butterfly valve;(4) welded butterfly valve

Q:What is the difference between turbine butterfly valve and flanged butterfly valve?: Worm gear flange butterfly valve, also known as worm gear flange plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. Butterfly valve plate installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely. When the flange butterfly valve is in the fully opened position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so that the flow control characteristic is better. Butterfly valve with bullet sealing and metal sealing two seal type. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.

Q:Fire, the signal butterfly valve flange connection or welding?: Fire signal butterfly valve is generally used to clamp type connection more, the clip type butterfly valve body is without flange, that is to say, with two flanges on the pipe, then screw the butterfly valve. Followed by the butterfly valve itself with flanges, and then the pipe flange with screws connected, this is the flange connection. Fire welding less use, pressure is not high!

Q:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?: Well definitely should not mess with it, especially if you do not know exactly what it is and more important what it controls. If not water, then it could possibly be the shut off for a near by gas appliance. It would help if you described the size and color of the pipe. Maybe you could try to trace it , where does it come from and where does it go to ?
