Globe Valves

Globe valves are valves used in various industrial applications, like water treatment, seawater processing, steam, food and beverage production, marine vessels, HVAC, and chemical processing.

Laminar’s globe control valves stand for the highest quality. They are used even under tough conditions, such as for industrial water and wastewater treatments or chemical/chlorine applications, as well as for chemical and milk of lime systems.

Globe valves have a spherical body and consist of either a movable plug or disc element and a stationary ring seat.

With the ability to handle a wide range of temperatures and pressures, they are typically used to regulate the flow of liquids or gases. However, they can also be used as shut-off valves. They are either integrated or screwed into the valve body. The disc guides are cast into the valve body for higher-pressure applications.

The main purpose of globe valves is full or partial (with throttling or regulating function) shut-off of the medium working flow. Their main features include:

  • Tight shut-off and effective controlling capabilities
  • Compact design and simple construction
  • Uncomplicated maintenance and repair
  • Modular design with few parts required

In addition, their design makes them more reliable than other types of valves, as they are less prone to leakage or malfunction due to wear and tear.

The most common type of globe valve is the threaded plug valve, which has an externally threaded stem that can be adjusted to regulate the flow rate through the system. Other types include flanged and welded globe valves.

Globe valves can be made from various materials, including bronze, stainless steel, cast iron, cast steel, and other metals.

The size of globe valves is also essential when selecting the suitable valve for a particular application. Generally, larger valve sizes are better suited for heavier-duty applications requiring higher pressures or temperatures. Using the correct size valve for a given application is vital to ensure it can perform its intended function safely and efficiently.

When selecting a globe valve, it is crucial to consider the manufacturer’s specifications. These will include details about the material used to make the valve, its size and pressure rating, and any necessary maintenance requirements. Additionally, it is important to ensure that the valve meets all applicable safety standards.

Globe Valves shall be designed for equal percentage flow characteristics when handling water. At the same time, they should have linear flow characteristics with steam applications.

A balanced single-seated globe valve is designed for HVAC applications. This globe valve can be supplied with a pneumatic, electric, or hydraulic actuator, similarly, also for our bellows sealed globe valve with double sealing design.

Solenoid Valve

Solenoid valves are essential components in controlling the flow of liquids and gases for a wide range of applications.


A globe valve comprises a few simple parts, each essential in controlling the flow of liquids or gases.

The valve’s body is the main component and houses all other parts. Depending on the application, this part can be made from various materials such as bronze, stainless steel, cast iron, or other metals. The seat rings are inside the valve body and form a seal between it and the rest of the valve.

The valve stem is attached to the top of the valve body and is used to open and close it. It has an adjustable disc or plug or trim, which can be rotated to control the flow rate through the valve. The disc guides are also inside the valve body and help keep the stem in place when it is opened or closed.

The disk can either close the flow path altogether or be removed entirely from the flow path.

Finally, two bonnets on either side of the valve body help secure all other parts in place. They also provide a tight seal between the interior of the valve and its surrounding environment, allowing for better pressure control.

Globe valves come in various sizes, from small 1/4” valves to larger 12” models.

Depending on the application, different sizes may be needed to provide a particular system’s necessary fluid flow, flow rate, and pressure rating. Smaller ones are best suited for lighter-duty and low-pressure applications such as residential water systems.

Larger globe valves are ideal for high-temperature and high-pressure applications.

When selecting the proper size valve for an application, it is important to consult the manufacturer’s specifications to ensure the valve meets the required pressure and temperature ratings.

The designs mainly depend on the application of the globe valves. The design standard for globe valves in the oil, gas, and process industries is typically based on the American Society of Mechanical Engineers (ASME) B-16.34 Pressure Temperature Ratings Standards.

These standards set forth the requirements for maximum allowable pressure, temperature ratings, and factors such as minimum wall thickness, material selection, and other design features.

There are 2-Way and 3-Way Globe Valves for chilled and hot water applications, which are used for proportional control of hot or chilled water and glycol solutions and two-position control of low-pressure steam in closed-loop HVAC systems. Available in both flanged design and threaded ends design.

Globe valves are renowned for their versatility, reliability, and longevity.

They can operate in a wide range of temperatures and pressures and can be used to control the gas or fluid flow. The directional design reduces turbulence and enhances accuracy, which makes them ideal for applications such as steam systems, waterworks, hydraulic systems, and other industrial processes.
Moreover, globe valves are known for their tight seal capabilities. In cases where pressure drops, the valve remains closed due to the force exerted by the spring. This ensures that no fluid will leak out from the valve, which is essential in preventing hazardous spills or environmental damage.

Globe valves can handle pressure limits from 145 (PN10) to 1500 psi (PN100).

However, the globe valve design is not recommended where accurate flow control is critical. Globe valves are also unsuitable for frequent throttling because this can cause the valve to wear out quickly or even fail due to excessive pressure drops.

In addition, they should not be used in applications where the prevention of reverse flow direction is needed.

When selecting the suitable valve for a specific application, it is important to understand the difference between a ball valve and a globe valve.

While both valves control the flow of liquids or gases, they each have unique features that make them better suited for different applications.

A ball valve is designed with a disk-shaped closure element with two hemispherical-shaped depressions on either end. Its shape allows it to be opened and closed quickly, making it ideal for applications where rapid shutoff is desired. Its simple design also makes it easier and inexpensive to maintain than other valves.

The globe valve design is more intricate and is ideal for applications where precise flow control is needed. It features an adjustable threaded stem that allows for better flow rate adjustment. It is an excellent choice for regulating pressure between two points or controlling the speed of pumps in fluid systems. Furthermore, its tight seal capabilities make it suitable for working with hazardous liquids and gases.

When selecting the suitable valve for a particular application, it is essential to consider the type of environment it will be used in and any specific requirements or factors that may affect its performance.

In general, ball valves are best suited for applications that require fast shutoff, while globe valves are ideal for applications that require precise control.
