Product Description:

1. Manual Wafer Butterfly Valve Description

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. 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. Small in size and light in weight, easy instillation and maintenance. It can be mounted wherever needed
2. Simple and compact construction, quick 90 degrees on-off operation
3. Minimized operating torque, energy saving
4. Flow curve teeing to straight line, excellent regulation performance
5. Long service life, standing the test of tens of thousands opening/closing operations
6. Bubbles-tight sealing with no leakage under the pressure test
7. Wide selection of materials, applicable to various mediums

 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:It is different from the butterfly valve butterfly valve
Butterfly valve is clear that the butterfly, because it is so called as valve plate, butterfly valve.
Q:Timing belt reason for bent valve?
Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.
Q:What is an electric two position butterfly valve?
Answer for you:Shanghai Huquan electric valve manufacturer of electric double position butterfly valve this product is connected with the flange clamp. Material: cast iron, carbon steel, stainless steel, 304/316Product overviewElectric double position butterfly valve (soft seal) is suitable for temperature less than 200 DEG C, adjust the flux and closure of the role of the medium nominal pressure is less than 1.6MPa of food, medicine, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipeline.main features1., the design is novel and reasonable, unique structure, light weight, fast opening and closing.2., small operation torque, easy operation, labor-saving and smart.3. can be installed in any location, easy maintenance.4., seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5., sealing material aging resistance, corrosion resistance, long service life and so on.Electric double position butterfly valve adopts standardDesign standard: gb/T12238-1889Flange connection size: gb/T9113.1-2000; GB/T9115.1-2000; jb78Structure length: gb/T12221-1889Pressure test: gb/T13927-1992; jb/T9092-1999
Q:Gate valve and butterfly valve which is installed when there is a direction?
Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.
Q:HOW TO CHANGE THE PCV VALVE HOSE?
just undo the clamps, and pull. it may need some wiggling and tugging, as its been on there for 9 years now without moving. put on your new hose, and replace the clamps, and youre done. next time, try not using all caps. it doesnt make us want to answer your question anymore just because its in caps, in fact, maybe a little less.
Q:Especially butterfly valve
Butterfly valve is fully open to fully closed is usually less than 90 degrees, the opening refers to the butterfly plate rotation angle;Linear closing should be the locator is linear, if the potentiometer is 0-10 euro, corresponding to 0-90 degrees, 500 Europe, opening 45 degrees;
Q:Pulmonary Valve Stenosis?
1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.
Q:What's the material of the butterfly valve seat?
The seating material shall meet the following criteria:1) fluid compatibility, including expansion, hardness loss, permeability, and degradation;2) hardness;3) permanent deformation;4) the degree of recovery after load removal;5) pull in and compressive strength;6) deformation before fracture;7) modulus of elasticity.
Q:whats the name of that valve under the kitchen sink?
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 ?
Q:What are the advantages of butterfly valves?
B. is cheap, especially when the caliber is big;C. the resistance loss is small and the fluid decreases through pressure;
