Q:How does the pneumatic butterfly valve control the angle of opening?

The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator

Q:Butterfly valve sealing material has several?

Butterfly valve sealing material has nine kinds:X1 (natural food gum);X2 (Heipalen);X3 (ethylene propylene rubber);X4 (chloroprene rubber);X5 (Ding Qing rubber);X6 (abrasion resistant rubber);X7 (fluorine rubber);X8 (silicone rubber);X9 (heat resistant ethylene propylene rubber).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:Types of butterfly valves

There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,

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:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?

Axis is not the same, so fast reaction, small wear.

Q:Butterfly valve is generally used in what position?

Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.

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:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?

The clip type valve bolts are generally longer, in high temperature conditions, bolt expansion may lead to leakage, so the high temperature conditions are not suitable for large diameter.But for the end and downstream pipeline occasions need to remove the clip on butterfly valve is generally not, because when the downstream flange dismounting clamp down, the valve will fall down, it must do in order to remove the nipple, and the flange type butterfly valve does not exist on the surface of the problem, but the cost will be relatively high.

Q:What's the difference between D71X-16 and D71H-16 butterfly valves?

Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.

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).
