What are Steam Control Valve

Steam control valve

Steam control valves are essential components in various industrial applications, from electricity generation to chemical and food processing. But they are also used in other areas, such as cleaning, heating, and humidification equipment. With their ability to manage steam pressure and flow, these valves provide reliable and efficient operation for all industrial processes. So whether you are in the energy production, chemical, or food processing industries, investing in industrial steam control valves can help improve efficiency and productivity.  

Steam has long been a reliable and efficient source of heat energy for industrial production, and its importance is only increasing. With steam control valves playing a key role in maintaining efficiency and productivity, it’s essential to have state-of-the-art valves to maximize effectiveness. Steam control valves have the potential to reduce energy costs, increase productivity and help maintain the highest standards of safety. Investing in the latest technology will ensure you’re making the most of your steam energy and that your production is as efficient and effective as possible.

What is Steam Control Valve?

Typically, valves control the flow of a liquid or gas in a system. But steam control valves are a bit more complex, as they regulate the flow of steam or vapor and control the temperature and pressure of the vapor or liquid. This allows for precise regulation and ensures that a system runs at peak efficiency.

Steam control valves are essential to regulate the pressure of steam, liquid, or gas and, thus, maintain the desired temperature. By compensating for any load disturbance caused by changes in pressure, these valves help to ensure that your process runs smoothly and efficiently. In addition, with their ability to accurately measure, monitor, and adjust the pressure of any substance, steam control valves give you the peace of mind that your process is functioning as intended.  

Automatically operated steam control valves are the perfect addition to any control loop fitted with a temperature and pressure sensor. By sending signals to regulate the steam flow, the controller ensures that the desired process condition is always maintained for maximum efficiency. The steam control valve then adjusts the condition of the steam to ensure the process remains running smoothly and efficiently. With this combination of controller and valve, you can ensure that your operation runs smoothly and efficiently with minimal effort.

An overview of Steam Control Valve Types, Applications, and Advantages

When looking for the best steam control valves for regulating steam pressure and temperature in an industrial system, you may need help with the many options on the market.   However, only a few valves are preferred for this purpose. These include:

  • Globe valve
  • Ball valves
  • Butterfly valves

Each of these valves offers unique benefits and challenges, allowing you to find the one that best meets your specific requirements. With a suitable valve in place, you can maintain safe and reliable steam pressure and temperature control in your industrial system.

Globe Valves

Globe valves are known for their spherical body shape and internal partition, which separates the body into two. The circular opening in the partition creates a seat for a moveable plug or disc, which can be screwed down to close the valve and stop the fluid flow. This precise level of control makes globe valves ideal for regulating flow rate in various applications – from fully open to fully closed. Moreover, globe valves offer superior accuracy and durability.


Globe valves are essential components for various industrial and commercial applications systems. Globe valves are typically used in the following applications:

  • Chemical feed systems
  • Boiler and central steam vents and drains
  • Turbine lube oil systems
  • Cooling water systems
  • Fuel oil systems

Globe valves are designed to withstand high pressure and temperate conditions, making them a reliable solution for various applications. Their robust construction ensures long-term performance, while their simple design allows easy maintenance and installation.


Globe valves offer numerous benefits, making them suitable for use in various high-pressure and high-temperature systems.

  • They offer excellent shutoff capability, making them perfect for controlling and regulating fluid flow.
  • Additionally, globe valves are easy to maintain and resurface the seats, making them a cost-effective and reliable solution for your system.
  • Superior performance and ease of maintenance.

Ball Valves

Ball valves are an efficient and reliable way to control the flow of steam or liquid in a system, as the rotary ball blocks the flow when pushed to one side and allows it when pushed to the opposite side.   This makes them more popular than gate valves for use as shutoff valves, as they have a long lifespan and form a reliable seal.

However, their limitation in accurately controlling the flow rate makes them unsuitable for industries that require high accuracy. Therefore, ball valves are only used as control valves in exceptional cases where their other benefits make them a viable option.


Ball valves are versatile pieces of equipment that are most commonly used in a variety of applications, including:

  • Cooling water systems
  • Feedwater systems
  • High-point vents and low-point drain services.
  • Bubble-tight services for liquid and gaseous applications and steam service.
  • They are also used in instrument isolation to create a reliable seal.

Their excellent sealing capabilities provide reliable performance in all these applications.


The use of ball valves offers a range of benefits that make them the ideal choice for any application. The following are some of the top advantages of using ball valves:

  • Lightweight and compact design – ball valves are much smaller and lighter than gate valves, making them easier to install and maintain.
  • Quick to open and close – ball valves are designed to open and close quickly, allowing for quick responses to changing conditions.
  • Versatile multi-port designs – ball valves feature multi-port designs that help improve versatility and reduce the number of valves needed.
  • Long life spans – ball valves are designed to last for years, making them a cost-effective choice.
  • High-temperature and high-pressure applications – ball valves are highly efficient in extreme temperature and pressure conditions.

Butterfly Valves

The principle behind butterfly and ball valves is quite simple; by rotating its disk, the butterfly valve can close or open the gas or liquid flow. As a result, butterfly valves are highly sought-after due to their low costs, lightweight design, fast operation, and easy installation. However, to ensure accurate control over the valve’s process, you’ll need to equip it with a gearbox, handles, or automated actuators. With these additions, you can easily monitor and adjust the flow of your liquids and gases.


Butterfly valves are some of the most versatile and widely used valves in the industry today. With applications in the:

  • Food and beverage
  • Chemical
  • Oil and pharmaceutical
  • Wastewater treatment
  • Water and gas supply
  • Fuel handling
  • Fire protection industries


  • Low purchase and maintenance costs make them an economical choice for many applications.
  • Fast opening and closing, allowing for quick and efficient control.
  • Light and compact, making them easy to install and transport.
  • Reasonably accurate flow control, allowing for precise regulation of fluid flow.
