What is a globe Valve?

A globe valve is an instrument used to globe and/or control the flow of fluid in a pipeline. It works by globeping fluid from flowing through the pipe. The name ball valve comes from the cylindrical shape of the valve. There are usually two valve body halves inside a globe valve, separated by an internal baffle.

Although globe valves exhibit greater pressure drop than gate valves, you can use them in situations where the pressure drop across the valve is a non-controlling factor. When used for throttling purposes, another name for a globe valve is a throttle valve.

globe Valves Features

Cast iron screw globe valve has a simple structure, low price, and easy maintenance.

The valve body is embedded with a brass valve seat to enhance sealing performance.

We perform pressure testing on each valve to ensure that the product is 100% leak-free after sale.

The product has a small working stroke and short opening and closing time.

The product has good sealing performance and small friction between sealing surfaces, so it has a long service life.

How are globe valves made?

Due to the complex shape of the flow channel, most globe valves are made of castings. However, they can also be made from forged materials for specific applications.

The cast valve disc and seat ring of the globe valve are mostly made of bronze. On the other hand, steel globe valves with temperatures above 350°C have trims made of stainless steel. This is essential to provide anti-seize and wear properties. It is critical to heat treat the valve's mating surfaces to obtain different hardness values. Manufacturing globe valves also involves the use of other trim materials, such as cobalt-based alloys.

It is also critical to grind the seat surface to achieve full-bearing

What industries or companies use globe valves?

Where appropriate, globe valves are used in many process industries. However, their application determines the internal structure of the valve. For example, a ball control valve will have internal components designed to control process fluids.

Globe valves are widely used in the factory piping industry and can be operated manually or automatically. Unlike gate valves, globe valves will help regulate pressure flow and complete the flow of liquid or shut off completely.

What are the most common applications for globe valves?

globe valves are primarily used in basic faucets. Turn the handwheel and the disc will drop or rise. If the disc drops to its maximum, the water supply is completely shut off. However, when the disk is in its highest position, the water flow reaches its highest rate. In a wider industrial environment, an electric actuator may be used instead of a manual handle to seal a globe valve.

There is usually a baffle inside the globe valve. The baffle causes the liquid to change direction and pass through the baffle. This means the fluid cannot flow freely and causes the pressure in the valve to drop. globe valves are not compatible with slurries or thicker liquids where the baffle may clog.

What is the purpose of a globe valve?

Many types of valves can be designated as globe valves. They can be isolation valves, control valves, etc. As mentioned earlier, the sphere refers to the spherical shape of the valve body.

The main purpose of globe valves is to globe, start, and regulate the flow of liquids and gases in pipelines. It usually has a movable disc component and a non-movable ring seat in a cylindrical body. The seat of a globe valve is located in the center of the pipe and alongside the pipe, while the opening of the valve seat is closed using a disc or plug. The construction of globe valves allows them to handle flow in both directions.

FAQ

Q1: What is the purpose of the globe valve?

A: A globe valve is an instrument used to globe and/or control the flow of fluid in a pipeline. It works by globeping fluid from flowing through the pipe. The name ball valve comes from the cylindrical shape of the valve. There are usually two valve body halves inside a globe valve, separated by an internal baffle.

Q2: What is the difference between a globe valve and a gate valve?

A: Globe valves also operate differently from gate valves. They can change flow direction and flow rate, whereas gate valves can only perform a complete on/off function. They should not be used to control flow as this can cause component degradation.

Q3: What is the difference between a ball valve and a globe valve?

A: The main difference between these two types is how they close. Globe valves use a plug (stem) that closes against the flow, while ball valves have a gate (ball) that closes against the flow. Globe valves are suitable for regulating flow, while ball valves are more suitable for on/off control without pressure drop.

Q4: What is the difference between a globe valve and an angle valve?

A: Angle valves have the same stem, disc, and seat ring design features as globe valves. The fundamental difference between the two is that the fluid flowing through the angle valve makes a 90° turn. These valves offer less resistance to flow than the elbow-equipped globe valves they replace.

Q5: Why use a globe valve instead of a gate valve?

A: The globe valve is mainly a control valve. Gate valves are designed for media isolation rather than flow control. Globe valves are one-way and are best suited for applications where pressure changes are not an issue.

Q6: What is the service life of the globe valve?

A: Many ball valve manufacturers provide estimates of expected ball valve life (usually eight to ten years), and proper maintenance can certainly extend this range. However, the service life of a ball valve can be affected by a variety of other factors.

Q7: How to distinguish gate valves and globe valves?

A: A globe valve is different from most valves in that its name comes from its body shape (round shape) rather than its disc, as is common with gate valves. Its disc moves up and down to allow or block flow, similar to a gate.

Q8: Which is better, the globe valve or the gate valve?

A: Applications: Because globe valves experience such drastic pressure changes, they are ideal for applications that are not affected by pressure drop. Gate valves are multi-directional and are suitable for applications that are more sensitive to pressure drop.

Q9: Can the globe valve reverse flow?

A: Globe valves are designed to start and globe flow like most valves and are also suitable for throttling fluids and changing pressure. Another benefit of a shut-off valve is its ability to prevent backflow. It can be visually recognized by its round body. Globe valves do not directly allow fluid to pass through them like gate valves.

Q10: Should the globe valve be fully open?

A: Globe valves are ideal for throttling or regulating media flow in the partially open position and making starting and globeping flow less abrupt, which helps prevent water hammer.
