What are the types of electric globe valves commonly used?

According to the channel direction.

1) Straight-through globe valve 2) Direct-flow globe valve: In the direct-flow or Y-shaped globe valve, the flow channel of the valve body is oblique with the main channel, so that the degree of damage in the flow state is smaller than that of the conventional globe valve, so the pressure loss through the valve is correspondingly smaller. 3) Angle globe valve:

In an angle globe valve, the fluid only needs to change direction once, resulting in a smaller pressure drop through this valve than a conventional globe valve. 4) Piston globe valve: This form of globe valve is a variant of the conventional globe valve.

In this valve, the disc and seat are usually designed based on the plunger principle. The disc is ground into a plunger connected to the stem, and the seal is achieved by two elastic seals that are sleeved over the plunger. The two elastomeric seals are separated by a collar and are pressed against the seal around the plunger by a load applied to the bonnet by the bonnet nut.

Replaceable seals can be made of a wide variety of materials, and the valve is mainly used for "on" or "off", but is available with a special form of plunger or special collar that can also be used to regulate the flow rate.

Thank you! As a hydraulic engineer, I can tell you that there are several types of globe valves that are commonly used:

1.Handwheel globe valve: This is the most commonly seen type of globe valve, which uses a handwheel to operate the valve's on/off valve. By rotating the handwheel, the valve can be opened or closed, controlling the flow of fluid.

2.Electric shut-off valve: This type of shut-off valve uses an electric drive to open or close the valve through remote control or automatic control. It is often used in large piping systems or where remote operation is required.

3.Pneumatic shut-off valve: This type of shut-off valve uses a pneumatic drive to control the opening and closing of the valve by air or gas pressure. It has the advantages of fast response and high reliability, and is commonly used in high-pressure piping systems.

4.Butterfly valve: A butterfly valve is a globe valve that uses a disc installed in the valve body to control the flow of fluid. It has a simple structure, small size, and has the characteristics of fast switching and low pressure loss, and is widely used in small and medium-diameter pipeline systems.

5.Ball valves: Ball valves use holes and balls inside the ball body to control the flow of fluid. It has the characteristics of light handling, good sealing and long life, and is often used in high temperature and high pressure or where rapid shut-off of fluids is required.

6.Soft Seal Globe Valve: Soft Seal Globe Valve uses soft seals to achieve the sealing of the valve, which has the characteristics of good sealing performance, light operation and convenient maintenance. It is commonly used in piping systems at low to medium pressure.

The above are several commonly used globe valve types, and it is important to choose the right globe valve type according to the specific application scenario and requirements. Hope it helps! If you have any other questions, please feel free to ask me.

A globe valve is a type of valve that is used for sealing. It is widely used in our production and life. Let's take a look at the classification of globe valves.

Speaking of which, you may have such doubts, so what is the working principle of the copper globe valve? Let's introduce it to you.

Copper globe valve is the most commonly used valve in our lives, so why is it so popular among consumer groups? It is because of its own metal material that makes it more durable, and it is cheap, simple to manufacture and many other advantages in one, suitable for various working environments under pressure. The working principle itself is also very simple, that is, the force is applied through the valve stalk, and then the disc and the valve seat are tightly closed together, so as to prevent the flow of the medium.

Here we would like to remind you that we should pay attention to the direction of the globe valve when installing the globe valve notice, because it only allows the medium to move in one direction. If you want to cut off the flow of media for a long time, it is not recommended to use it, because it does not have a strong long-term sealing ability. Let's introduce the classification of globe valves.

Here, according to the position of the thread on the globe valve, it can be divided into upper threaded stem globe valve and lower threaded stem globe valve. The difference between these two types of globe valves is that the thread of the former is outside the valve body, while the latter thread is inside the valve body, each has its own advantages, the former is more commonly used, and the latter is only used in small diameter and low temperature.

Then, according to the different channel directions of the globe valve, it can be divided into four types: direct flow globe valve, angle globe valve, plunger globe valve, and straight-through globe valve. Let's briefly introduce the advantages of these four globe valves. The first type of flow shut-off valve is a diagonal line between the valve body and the medium flow channel, which reduces pressure loss.

The second type of angle globe valve is that the medium in the valve body only needs to change the direction once, which also reduces the valve pressure need. The fourth type of piston globe valve, this kind of globe valve is the most complex, so I will not introduce it in detail here.

A globe valve can be called a shut-off valve or a throttle valve. The difference between a manual shut-off valve and an electric shut-off valve is that the valve body is the same.

Manual shut-off valve refers to the valve that is manually or manually operated by switch, and is generally used in a place far away from the working place for normally open or normally closed (infrequent switching) or close to the working place (often opening or adjusting). The electric globe valve refers to the removal of the handwheel in the same valve body and the configuration of electric actuator to control the switch and adjust or remote control switch and adjustment, which is suitable for various occasions. With the development of modern industry, more and more factories (projects) have chosen industrialized automatic control methods.

The younger brother expressed his opinion for the first time, if there were any differences or opinions. We can talk about it.

The shut-off valve is generally used for shut-off, but it can also be used for throttling. The valve body of the manual shut-off valve and the electric shut-off valve is the same, and the driving mode is different, one uses hand and the other uses electricity.

The globe valve is a common pipe connection device in many of our industrial facilities, which controls the speed of the fluid in our pipeline, so that it can be well isolated from the outside world, creating a very closed environment for it. The media used in different production is different, which requires us to correspond to different types of globe valves, of course, the characteristics of these products are also different. This article will give you a brief introduction!

What are the types of globe valves?

1. Water-sealed globe valve.

The main working medium of the water-sealed globe valve is water, steam, oil and non-corrosive gas, which is used as an opening and closing device, especially suitable for the vacuum condensation system of steam turbine in thermal power plants, and has two forms: globe valve and gate valve. It is suitable for nominal pressure 10MPa and operating temperature 400 or 550 °C. The bonnet packing chamber has a water-circulating sealing structure when water is introduced into the interface.

It can isolate the system from the atmosphere and ensure that the system has good air tightness. When used for opening and closing on the pipeline, it must be in a fully open or fully closed state, and shall not be used to regulate the flow rate.

2. Antibiotic shut-off valve.

Antibiotic shut-off valve is a special type of shut-off valve, which has a strong sterilization and detoxification function to prevent product infection. It is mainly used in biological fermentation, medical and beer fermentation, amino acid fermentation, biological agricultural fermentation, biological fertilizer fermentation, various antibiotic fermentation, biological, biochemical, chemical materials, water, steam, cold control and other fields.
