Q: What is the electric butterfly valve? Please, great God!: Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.

Q: Butterfly valve general use occasions: Butterfly valve general use occasions:1 、 soft sealing butterfly valve applies to ventilation, dust removal pipeline two-way opening and closing and adjustment, metallurgy, light industry, power, petrochemical systems, gas pipelines and waterways.2, metal sealed double eccentric butterfly valve, suitable for heating, steam, water and gas, oil, acid and other pipelines, as the adjustment and closure devices.3, metal seal three eccentric butterfly valve, in addition to as large pressure swing adsorption gas separation control valve.4, metal seal three eccentric butterfly valve, can be widely used in petroleum, chemical, metallurgy, electricity, food, medicine, water supply and drainage, gas transportation and other fields.

Q: Water supply pipe gate valve and butterfly valve which good?: Butterfly valve is relatively applicable1 electric butterfly valve 0-90 degree rotation angle stroke valve, specific flow characteristics, small size, high performance price ratio2, electric valve up and down movement of the straight stroke control method, can be used as shut-off valve, large size, expensive3, electric butterfly valve can not be used for high temperature and high pressure conditions, not wear-resistant. Electric gate valve is generally used to close the material with a grain of material, suitable for high temperature and high pressure conditionsOur company specializes in the production of various types of valves, there is a need to help me, I would like to help

Q: How warm is the PTFE butterfly valve?: PTFE butterfly valve, sealing surface of fluorine plastic, temperature -29 ~ 450 degrees

Q: What are the classification criteria for pneumatic butterfly valves?: Pneumatic flange butterfly valve, pneumatic flange butterfly valve, this product is made up of rubber sealed butterfly valve and carbon steel or stainless steel valve plate and valve stem. Suitable temperature is less than or equal to 80 to 120 DEG C, such as food, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipes to regulate the flow and closure of the role of media.Pneumatic control valve is a valve (valve plate) around the rotating fixed axis perpendicular to the channel, which is composed of double or single acting piston (spring reset type) pneumatic actuator and butterfly valve, a rotary type high performance adjust or cut off valves, electric, pneumatic valve positioner or electromagnetic valve, air filter regulator, limit switch (valve position), can be realized on the fluid medium in the pipeline and process to adjust the proportion of the two cut off control, automatic control to achieve the parameters of the fluid flow, pressure, temperature, liquid level etc..

Q: Butterfly valve network and ordinary butterfly what is the difference?: Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.

Q: For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious: The direction of the arrow on the valve body refers to the direction of the medium.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. 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: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.: When talking about car engines, references such as v4, v6, v8, v10 and v12 are not for the number of valves. it is for the number of cylinders. The more cylinders that an engine has, the more fuel it consumes and most of the time, the more horsepower it can make. There are exceptions to this though. Regarding the noise of the engine, i would agree that a v8 sounds very good when it is roaring. Valves are actually the openings for fuel to get into the cylinders and the exhaust to come out from. Most modern engines have two valves for incoming fuel and two valves for the exhaust making a total of four valves per cylinder. hope that clears it for you

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: Which is more expensive, gate valve or butterfly valve?: Same diameter, the same material, with the pressure level, the weight of the gate valve is much heavier than the butterfly valve, about 2 times of the butterfly valve!
