Product Description

As their name suggests, globe valves are linear motion valves with rounded globular shaped bodies. Since their shape is similar to other valve bodies, positive identification must be made based on internal piping. Recently globeGlobe Valve image valves have lost their traditional round body-shape. Globe valves have many advantages and disadvantages for users. They have excellent and precise throttling ability for high-pressure systems. The disadvantages include low-flow coefficients and a longer operating time because the operator must turn the handle and stem many times to ensure the valve is completely open or completely closed. Globe valves can be used in systems that require frequent stroking, vacuum, and systems that have a wide range of temperature extremes.

Classification

 

Industrial Valves  can be classified in a number of different ways including method of control and valve function. Globe valves use a linear motion disk and function to start, stop, and throttle fluid flow.

 

Method of Control

Globe valves have a disk which can completely open or completely close the flow path. This is done with the perpendicular movement of the disk away from the seat. The annular space between the disk and seat ring gradually changes to allow fluid flow through the valve. As the fluid travels through the valve it changes direction many times and increases the pressure. In most cases, globe valves are installed with the stem vertical and the fluid stream connected to the pipe side above the disk. This helps to maintain a tight seal when the valve is fully closed. When the globe valve is open, the fluid flows through the space between the edge of the disk and the seat. The flow rateGlobe Valve image for the media is determined by the distance between the valve plug and the valve seat.

 

Globe Valve Function

Globe valves are commonly used as an on/off valve, but they may be used for throttling systems. The gradual change in spacing between the disk and seat ring gives the globe valve good throttling ability. These linear motion valves can be used in a variety of applications as long as the pressure and temperature limits are not exceeded, and the process does not require special materials to combat corrosion. Globe valve also have a smaller chance of damage to the seat or valve plug by the fluid, even if the seat is in the partially open position.

 

Media

Globe valves can be used for both gas and liquid systems. Globe valves are not specified for high purity or slurry systems. The valve has inherent cavities that easily promote contamination and allow slurry material to become entrapped, disabling the valve operation.

 

Globe Valve Components

 

Globe valves have a very distinct globe shape. The disk, valve stem, and the hand wheel are the moving parts in the valve body. The body is available in three different designs depending on the application as well as three different types of disks.

Body Construction

Due to the angles in the globe valve body there is a high level of head loss. Head loss is the measure of reduction in the total head of liquid as it moves through the system. Total head loss can be calculated by summing the elevation head, velocity head and pressure head. While head loss is unavoidable in fluid systems, it is increased by obstructions and discontinuities in the flow path such as the S shape of the globe valve design. The body and flow pipes are rounded and smooth to provide system flow without creating turbulence or noise. To avoid creating additional pressure losses at high velocity the pipes should be a constant area. Globe valves are available in three main body types (although custom designs are available as well): angle design, Y-shaped, and Z- shaped.

 

Angle: Angle valves are designed so that the inlet and outlet are perpendicular. They are used for transferring flow from vertical to horizontal.

Y-body: Y-body design valves, also known as cross-flow globe valves, derive linear action from the incline between the axis of the inlet and outlet ports. This design reduces the high pressure drop inherent in globe valves. The seat and stem are at a 45 angel with the media flow, for a straighter flow path at full opening. The Y-design also keeps the stem, bonnet, and packing in a relatively pressure-resistant envelop. This valve design is well suited for high pressures and other severe services.

Selection Tip:  The flow passage for small Y-body globe valves is not as carefully streamlined as it is for larger valves because pressure loss is less important for small size Y-body valves

 

 

Z- body: The Z-body design, also known as a straight-through globe valve,  is the simplest globe valve body. It is commonly used for water applications. Z-body globe valves have a Z-shaped diaphragm or partition across the globular body which contains the seat. Since the seat is horizontal, the disk and stem travel at right angles to the pipe axis. The stem passes through the bonnet which is attached to a large opening at the top of the valve body. The symmetrical form simplifies manufacturing, installation, and repair.

Bonnets retain the pressure in the valve by acting as a cap or cover for the body.
