Globe valve

Globe valve

The globe valve, also known as the shut-off valve, is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the force of the stem and the head friction of the filler and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve. , So the diameter of the valve stem should be large, otherwise the valve stem will bend failure.

The performance of the globe valve

The friction of the sealing surface of the globe valve is smaller than that of the gate valve, and it has the advantages of small opening height and suitable for high temperature media. The disadvantage is that the opening and closing torque is large, and it is not suitable for high temperature and high pressure media.

The closing principle of the globe valve

Relying on the pressure of the valve stem, the sealing surface of the disc and the sealing surface of the valve seat are closely attached to prevent the medium from flowing. The shut-off valve only allows the medium to flow in one direction and is directional when installed. The structural length of the shut-off valve is longer than that of the gate valve, and the fluid resistance is large, and the sealing reliability is not strong during long-term operation.

Important components of aerospace equipment

As one of the most important cut-off valves, the globe valve plays an important role in the aerospace field. As an important component of aerospace equipment, the shut-off valve realizes the functions of medium delivery, cut-off, and adjustment, and its sealing performance directly affects the safe and reliable operation of aerospace equipment.

Sealing pair structure type

The structural type of the seal is a relatively unfamiliar classification method, but it is also an important classification method. Among them, the plane seal has no friction when in contact, and does not require high accuracy. The conical sealing type has the best sealing effect, but it is easily damaged. The thrust of the medium with the guided seal type is borne by the valve body, which further enhances the sealing performance. The spherical surface has the advantage of long life.

Frequently Asked Question

Do you have any question?

Globe valves, so-called because of their outside shape, are widely used in plant piping. They are suitable for manual and automatic operation. Unlike the gate valve, globe valve can be used for regulating flow or pressures as well as complete shutoff of flow.

Gate valves are used for On-Off control while Globe valves are used for flow regulation. Gate valves offer little resistance to fluid flow in fully open position and also have small pressure drop across the valve. Is that correct? The globe valves are not.

The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.
