Introduction to AHU valve systems

AHU valve systems, also known as Air Handling Unit valve systems, are an essential component of HVAC (Heating, Ventilation, and Air Conditioning) systems. These systems ensure the efficient control and distribution of conditioned air throughout buildings, maintaining optimum comfort levels for the occupants. AHU valve systems play a crucial role in regulating the flow, temperature, and pressure of air within the HVAC system, making them a vital part of building infrastructure.

Importance of AHU valve systems in London

London, as one of the largest and most populous cities in the world, is home to numerous commercial and residential buildings. The demand for efficient and reliable HVAC systems in these structures is essential for maintaining comfortable indoor environments. AHU valve systems are particularly important in London due to the city’s diverse climate and varying temperature conditions throughout the year. These systems enable precise control over air temperature, airflow, and ventilation, ensuring optimal indoor conditions regardless of external weather factors. By providing efficient and effective thermal comfort, AHU valve systems play a significant role in enhancing the quality of life for London residents and workers.

Types of AHU Valve Systems

2-way control valves

2-way control valves are commonly used in AHU systems to regulate the flow of water or steam. These valves can either be open or closed, allowing or restricting the flow of fluid. The two-way valve design is primarily utilized for controlling the supply or return water temperature, thereby maintaining the desired indoor air temperature.

3-way control valves

3-way control valves are used when precise temperature control is required. These valves have three ports, enabling them to divert flow between two different paths. In AHU systems, 3-way control valves are typically employed for mixing or diverting water flow to achieve the desired supply water temperature. By modulating the flow between hot and cold water, these valves ensure accurate temperature control in the HVAC system.

Butterfly valves

Butterfly valves are quarter-turn valves that utilize a disc to control the flow of air or water. These valves are compact, lightweight, and cost-effective, making them a common choice for AHU valve systems. Butterfly valves are ideal for applications that require low-pressure drops and flow control.

Ball valves

Ball valves, as the name suggests, feature a ball-shaped disc with a hole in the middle. They provide reliable shut-off control and are suitable for isolation purposes in AHU systems. Ball valves offer a tight seal, minimal pressure drop, and excellent flow control capabilities, making them highly versatile in HVAC installations.

Globe valves

Globe valves are linear motion valves that utilize a plug (disc) and seat arrangement to control the flow of fluid. These valves are well-suited for applications that require throttling and precise control of flow rates. Globe valves are commonly used in AHU systems for regulating the flow of chilled water, hot water, or steam.

Components of AHU Valve Systems


Actuators are devices responsible for translating control signals into mechanical movements in AHU valve systems. These components drive the operation of valves, enabling the precise control of fluid flow. Depending on the application and requirements, actuators can be either electric or pneumatic. Electric actuators use motors to drive the valve operation, while pneumatic actuators utilize compressed air to control valve positioning.

Valve bodies

Valve bodies are the main housing units that enclose the working parts of the valves within AHU systems. These bodies are designed to provide structural integrity, support the internal components, and facilitate the flow of fluids. Valve bodies can be made from various materials, including metals (such as brass or stainless steel) or plastics (such as PVC), depending on the specific requirements of the application.

Stem packings

Stem packings, also known as valve stem seals, provide a seal between the valve stem and the valve body, preventing leaks. These packings are typically made from materials such as graphite or PTFE (polytetrafluoroethylene), which offer excellent sealing properties under different temperatures and pressures. Proper maintenance and regular inspection of stem packings are essential to ensure the integrity of the AHU valve system.

Seat sealings

Seat sealings, or valve seat rings, provide a tight seal between the valve disc and the valve body, preventing any leakage when the valve is closed. These sealings are critical to maintaining the integrity of the HVAC system and preventing unnecessary energy loss. Seat sealings are typically made from materials such as rubber, PTFE, or metal alloys, ensuring reliable and long-lasting performance.

Bonnet gaskets

Bonnet gaskets, also referred to as valve bonnet seals, provide a seal between the valve bonnet and the valve body. These gaskets prevent any leakage from the bonnet area, ensuring the proper functioning of the AHU valve system. Bonnet gaskets are commonly made from materials such as graphite or elastomers, offering excellent resistance to temperature, pressure, and chemical exposure.

Benefits of AHU Valve Systems

Improved energy efficiency

AHU valve systems play a vital role in optimizing energy consumption within HVAC systems. By regulating the flow and temperature of air or water, these valve systems help maintain the desired conditions with minimal energy wastage. Properly designed and installed AHU valve systems ensure efficient air circulation, reducing the workload on heating and cooling equipment, and ultimately leading to energy savings.

Precise temperature control

AHU valve systems enable precise temperature control in buildings, ensuring the comfort of occupants. By modulating the flow of air or water, these systems can maintain a consistent temperature throughout different zones within a building. Whether it is heating during cold winters or cooling during hot summers, AHU valve systems provide accurate temperature control, resulting in enhanced comfort levels.

Enhanced indoor air quality

AHU valve systems contribute to maintaining optimal indoor air quality by regulating the ventilation and air exchange rates. These valve systems enable the filtration and distribution of fresh air, removing pollutants and contaminants from the indoor environment. By providing a controlled and balanced airflow, AHU valve systems help prevent the accumulation of stale air and improve the overall air quality within buildings.

Extended equipment lifespan

Efficient AHU valve systems can significantly extend the lifespan of HVAC equipment. By ensuring proper flow rates, preventing excessive pressure drops, and minimizing the workload on heating and cooling equipment, these valve systems reduce wear and tear. This leads to fewer breakdowns and repairs, prolonging the operational life of HVAC components and reducing maintenance costs over time.

Installation of AHU Valve Systems

System design considerations

The installation of AHU valve systems requires careful consideration of system design parameters. Factors such as building size, occupancy, heating and cooling requirements, and airflow regulations need to be taken into account during the design phase.
