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:Which is more expensive, gate valve or butterfly valve?

Gate valve.Under normal circumstances, if you need to adjust the good point, to use the gate valve, and if better, you can choose the cut-off valve.But the price is also butterfly valve, gate valve, globe valve increasing.

Q:The difference between butterfly valve d71x_10s and d341s-10

Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.

Q:Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.

Simply the engine size and the number of cylinder, the 3.0 has 6 the 2.3 has 4, however both engines have four valves per cylinder(2 intakes 2 exhaust) and dual overhead cams(dohc)

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:Where are the exhaust valves, mud valves and butterfly valves?

Chemical plant with colloid, puffed agent and granule. Wine industry, paper industry. Butterfly valves are used in petroleum, chemical, food, pharmaceutical, textile, water and electricity, ships, urban water supply and drainage, smelting, and energy systems as regulating and intercepting devices.

Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?

Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.

Q:The water supply pipe is the gate valve And on the cross dry pipe are the gate valve? To answer the 30

1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.

Q:Transformer butterfly valve and pressure relief valve difference

The oil immersed transformer pressure release valve is a safety device installed in the transformer, when the internal pressure is less than the limit value of the transformer such as 35kPa, which is in closed state, when the transformer internal fault occurs, a large number of transformer oil by pyrolysis, produce large amounts of gas, the internal pressure of the oil tank increased dramatically when the opening pressure exceeds the pressure release valve when the pressure relief valve opens, the internal oil and gas overflow, to release the pressure, avoid the pressure on the inside of the lead tank cracking or permanent deformation, when the fault of transformer internal end, internal pressure tank to reduce pressure release valve closing pressure, it will automatically shut down to prevent outside air enter the inside of the tank or water.

Q:16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?

This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
