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. 

2.Main Features of the Manual Wafer Butterfly Valve 

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

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

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

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

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

5.FAQ

1. What is manual wafer butterfly valve?

 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 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. 

Q:What do you mean, handle, butterfly valve, hard back and soft back?
The butterfly valve of the handle butterfly valve is 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 between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.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.The hard back is the metal seal, and the soft back is the elastic seal.
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.
Q:What's the material of the butterfly valve seat?
Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.
Q:I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
Did you get that EGR valve from Cadillac dealership?? A lot of those aftermarket parts DO NOT LIKE Cadillac's!!!!!!!!!! I run into that all the time nor will we use any aftermarket parts due to the problems we have with them. Make sure that switch is working that controls the EGR valve. I have seen those fail also. You need access to a serive manual so you can command that switch on off check with a test light a vacuum gauge to make sure you are getting vacuum to that EGR Valve. Also, make sure that the ports are not clogged up with carbon, even check the pipe inside the throttle body opening, they should be clean inside those tubes !!!!!!!!!
Q:Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(
here okorder /... usually you can tell when a car needs the gasket to be replaced because it will leak oil where the gasket is at the bottom of the cover i think hes ripping you off because cars usually dont need to have the valve cover replaced, just the gaskets so take it to another mechanic and get another estimate
Q:Butterfly D371X5-16ZB1 what does each letter stand for?
Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters
Q:What's the meaning of butterfly valve d371po?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
Q:How to use the fire butterfly valve properly?
Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
Q:What does the triplex of pneumatic butterfly valve mean?
Air pressure reducing valve, filter, oil mist these three parts
Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
Just drive differently,Handle butterfly valve is generally small caliber, because generally small caliber torque smaller, can be directly opened and closed by handTurbine butterfly gear box drive stem rotation.The selection principle for when the stem torque is greater than 300N.M when used in gear box drive gear box, and use the handwheel control hand wheel force is not greater than 300 nm.
