Types of Globe Style/Cage-Guided Control Valves We Offer

Jordan Valve offers a comprehensive range of globe-style and cage-guided pressure and back-pressure regulating valves designed for precise control in industrial applications. This series includes various configurations to meet diverse process needs, including:

• Globe Pressure Regulating Valves – Featuring a straightforward yet effective design, these valves regulate downstream pressure with high accuracy, making them ideal for steam, gas, and liquid applications.
• Air-Loaded Globe Valves – These pressure regulators utilize an external air source for finer control over setpoints, providing enhanced responsiveness and adaptability in automated systems.
• Cage-Trim Pressure Regulators – Engineered for durability and precision, the valves use a cage-guided design to ensure stability and minimize wear, even in demanding conditions with fluctuating pressures.
• Piloted Back-Pressure Regulators – Designed to maintain a controlled upstream pressure, these valves use a pilot system for more accurate and consistent performance, making them suitable for applications requiring precise back-pressure control.

Jordan Valve’s Teflon and metal diaphragm options, quick-change seat rings, and unique sliding gate technology (available on select models) enhance performance, extend valve life, and reduce maintenance costs. These valves are commonly used in industries such as oil and gas, chemical processing, power generation and food and beverage.

How Does a Cage-Guided Globe Control Valve Work?

A cage-guided globe control valve features an internal movable plug or disc, which is attached to the valve stem and is guided by a surrounding cage structure. The cage is a fixed component that features precisely machined ports that guide the movement of the plug, ensuring its smooth and accurate movement in the valve body. It also controls the fluid flow by uncovering or covering the port areas in the cage when the plug is lifted or lowered. The guiding function of the cage enables this valve to act as a precise flow regulator, minimizing lateral forces on the stem. This valve design ensures superior stability and performance in many high-pressure drop applications.

Benefits of Using Globe Control Valves

Our globe control valves are designed for excellent pressure and fluid flow control across process industries. These valves are often chosen over competitor products due to the following reasons:

• The cage design of these valves helps center the valve plug, assuring better shut-off capabilities and minimizing the risk of potential leaks. These factors contribute to accurate flow control.
• The cage guides the plug, reducing wear and tear on the sealing surfaces and thereby extending the lifespan of the valve.
• The cage design of these valves helps mitigate cavitation by preventing the vapor bubble collapse and ensures quieter operation.
• These valves enhance operational efficiency as they are less prone to vibrations due to the stable guiding mechanism.
• They can be used for various applications involving corrosive or viscous liquids, process gases, or utility steam.

Applications of Globe Control Valves

We provide globe control valves for steam, liquid, and gas media applications that require flow regulation, tight shutoff and throttling capabilities. They are used to:

Cage Guided Globe Control Valve

Cage guided valves are widely used because of their many advantages. Let's learn more about them together.

For more 3 way globe valveinformation, please contact us. We will provide professional answers.

1. Easy to change the flow characteristics.

Sleeve adjustment valve in the fluid from the sleeve outward flow, known as the center to the outside flow direction. Conversely, the flow is called external to the center. However, it is usually used to flow from the lower part of the sleeve and out through the opening of the cage. There are 3, 4, or 6 throttle openings symmetrically located in the sleeve. The shape of the throttle openings is related to the desired flow characteristics. The flow characteristics of the control valve can therefore be easily changed by changing the sleeve (shape of the throttle opening).

2. Easy to install and maintain. 

The valve seat is pressed against the valve body by the valve cover and is not threaded. Easy to install and maintain.

3. Interchangeability and versatility. 

By replacing different sleeves, different flow coefficients and different flow characteristics can be obtained.

4. Noise reduction. 

To reduce control valve noise, sleeve control valves are available as a type with noise-reducing inner parts. It has a sleeve and spool with a number of small holes. The small holes are used to increase the resistance. The velocity head is converted into kinetic energy to reduce noise. Typically, this type of sleeve control valve can reduce noise by more than 10dB.

Therefore, they are widely used in applications where noise reduction is required. To reduce control valve noise, multi-stage pressure reduction methods can also be used. The total pressure drop at both ends of these noise-reducing control valves is distributed to all levels so that all levels do not cause the fluid to flash and cavitate.

This reduces the noise of the control valve and can weaken and prevent scouring and wear caused by flashing and cavitation. The bottom of the spool of the sleeve control valve is flat, so that if cavitation occurs, the impact from the rupture of the bubble does not act on the spool, but is absorbed by the medium itself. Therefore, the impact of cavitation of the sleeve adjustment valve is small, and the service life is long.

5. Leakage is larger than single-seated valves. 

As a result of the sleeve and the spool between the graphite piston ring seal. After the long-term operation, the wear of the seal ring makes the leakage of the sleeve adjustment valve larger than that of the single-seated valve.

6. Easy maintenance. 

The reverse sleeve control valve is particularly suitable for applications where the valve internals require frequent inspection and maintenance, as the spool can be removed from below.

7. Reduces the impact of unbalanced forces. 

Usually, there are two types of sleeve adjustment valves, one is a balanced valve, the other is an unbalanced valve. The balancing valve has a balancing hole on the spool so that the unbalance force on the spool is greatly reduced. At the same time, it has a damping effect, which is beneficial to the stable operation of the control valve. Therefore, this type of control valve is often used in applications with high differential pressure and low noise requirements.
