BUTTERFLY VALVE FLANGE DOUBLE ECCENTRIC DUCTILE IRON DN80- DN1200

Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?: Two way hard sealing butterfly valve:Two way butterfly valve on the valve body usually does not indicate the direction of the media arrow sign, in the design of two-way sealing butterfly valve stem force is greater than one-way butterfly valve stem. The same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter. At the time of installation, the butterfly plate can face or back the direction of the medium, without considering the flow direction of the medium.

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: What are the classification criteria for pneumatic butterfly valves?: The pneumatic clamp butterfly valve has a novel structure, and the structure of the valve body is short clamp structure for meeting the narrow space of the pipeline, and the outer zero leakage is in place, and the internal leakage conforms to the national standard.Pneumatic butterfly valve, connection flanges, the sealing clamp, lined with NBR, EPDM rubber, heat resistant ethylene propylene rubber, natural rubber, chloroprene rubber, fluorine rubber, PTFE, medium according to the chemical properties have a more rational choice.Pneumatic fluorine valve, corrosion fluorine valve using the bisection valve combination two, valve seat and valve liner valve work, integration, only full plastic seat and lining plastic disc contact with the media, the product can withstand any corrosion in molten alkali metal and fluorine elements ", which D71F46 stem and disc board (forging) as a whole, the surface is uniformly coated with a layer of FEP.

Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?: Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.

Q: What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?: Stop valve, leak small, gate valve, leak big, butterfly valve switch fast

Q: What are the functions and uses of butterfly valves?: Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.

Q: CAD drawing of butterfly valve: Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.

Q: i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II: The valve head is larger then the valve port, so it's not coming out of there. Pull the head.

Q: The difference between vertical and horizontal butterfly valves in municipal water supply: The general municipal water supply butterfly valve is mainly vertical installation, mainly due to underground pipe network, vertical drive device in the upper, easy to operate, and installation of smaller wells;Horizontal, usually large diameter butterfly valve, usually used in the main network, often open, not easy to collect slag.

Q: What is the D37-10Q butterfly valve?: It may be the D371, the turbine to the clip type soft sealing butterfly valve, from your model can also see that the pressure is 1.0MPa, the body is ductile iron. It could be the D373, the turbo clamp hard seal butterfly valve, which is more expensive than the soft seal.
