3. Feature:

This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.

4. Sealability:

The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.

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: How much is the Honeywell butterfly DN300?: Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up

Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?: Depending on the size of the valve and the opening and closing torque, the transmission mode is different (handle or turbine).

Q: Model specification for butterfly valves: 1. classification by structure(1) Central sealed butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2. by secret cover material classification(1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. classified by seal type(1) forced sealing butterfly valve (2) pressure sealed butterfly valve. (3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.4. classification by work pressure(1) vacuum butterfly valve. Butterfly valve with lower working pressure than standard atmosphere. (2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa. (3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa. (4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve. (5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.5. classification by operating temperature(1) high temperature butterfly valve. T>450 degrees C butterfly valve (2) medium temperature butterfly valve. 120 C6. classification by connection1 pairs of clip butterfly valve2, flange butterfly valve (3) lug butterfly valve. (4) welded butterfly valve.

Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?: Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that

Q: Where are the exhaust valves, mud valves and butterfly valves?: The exhaust valve is used for the heating of the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Mud valve, also known as cover valve, commonly used in urban water plants, sewage treatment plants sedimentation tank bottom discharge sludge.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.

Q: What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?: General large bore turbine.What is the difference between worm gear pair butterfly valve and center line worm gear butterfly valve?The structure is the same, but the model is different, the central line refers to the butterfly valve, an eccentric structure (371), the clip butterfly valve can do 371, you can do 373, etc.. In more detail, the clamp can be a midline type, 1 single eccentric, 2 double eccentric, 3 is 371372373 midline, then it can be flange connection, it can also be a pair of clamp connection

Q: That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!: I know there are automatic fire fighting systems and the oil industry.

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.: Exhaust Gas Recirculation It redirects a portion of the exhaust gasses from the exhaust manifold back into the intake manifold so they can be re-burned. This is part of the emissions system that has been used since the early 70's.

Q: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?: WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
