Floset (Terminal Unit Valve Sets)
FloControl FCU Valve solutions are designed to simplify installation, improve commissioning efficiency and support reliable heating and cooling system performance. We offer pre-assembled Fan Coil Unit Valve Sets (FCU Valve Sets) that can be directly mounted onto the FCU unit from any manufacturer, including PICV, ABV 4-Port and Commissioning 4-Port Fan Coil Unit Valve Sets, fully compliant with BSRIA BG29/21. Whether it is a standard or highly customised FCU Valve Set, the FloControl FCU Valve Package Assembly is supplied with one of the shortest lead times in the market. The Compact FCU PICV Valve Set and ABV-4 Port Fan Coil Valve Package is easy to select and is supplied pre-assembled, tested, set and ready to fit. The FCU Valve Set fits directly onto the FCU unit with 40mm centres over the FCU drip tray, making FCU Valve installation simple, quick and reliable. Either vertically or horizontally configured, the Compact Fan Coil Valve Package Range is particularly suited for small spaces and slimline units, where a compact FCU Valve solution can support efficient system performance.
While prefabricated FCU Valve Package Assembly solutions have gained traction in the industry, there is little consensus on terminology. In many projects, terms such as FCU Valve, FCU PICV Valve Set, Fan Coil Valve Package and FCU Valve Package Assembly are used to describe similar prefabricated solutions. Below is a glossary used in the industry to refer to prefabricated FCU Valve Package Assembly solutions.

The “Dominator” in Dominator Valve (Set) actually is a manufacturer trade mark, registered 20 years ago, which is widely used as a category name.
Fan Coil Hook Up, Flypass and Miniflush are examples of manufacturer names for the Fan Coil Valve Package or refer to some of the functionality of the Valve Arrangement, e.g. Flushing Bypass Arrangement.
Bottom line, the different terms all refer to the same functionality of controlling the terminal unit and offering flushing & isolation options as a minimum.
Frequently Asked Questions
What is an FCU Valve Set?
FCU Valve Sets are prefabricated valve assemblies designed for fan coil units. They help regulate flow, simplify installation, and improve HVAC system efficiency by ensuring correct water distribution.
What is included in a Fan Coil Unit Valve Package?
A Fan Coil Unit Valve Package typically includes control valves, isolation valves, strainers, flexible hoses, test points, and balancing components depending on the project specification.
What are the benefits of pre-assembled FCU Valve Sets?
Pre-assembled FCU Valve Sets reduce installation time, improve commissioning efficiency, minimise on-site assembly work, and help reduce the risk of installation errors.
What is the difference between a PICV and a 4-Port FCU Valve Set?
PICV FCU Valve Sets provide automatic flow control and balancing, while 4-Port FCU Valve Sets are commonly used within heating and cooling changeover systems.
Are FloControl FCU Valve Sets BSRIA BG29 compliant?
Selected FloControl FCU Valve Packages are designed to support BSRIA BG29 compliance requirements and help improve installation consistency across HVAC projects.
Where are FCU Valve Sets commonly used?
FCU Valve Sets are commonly used in commercial offices, hotels, healthcare facilities, residential developments, education buildings, and mixed-use projects.
Why is an FCU PICV Valve Set used in HVAC systems?
An FCU PICV Valve Set is used to maintain accurate flow control even when system pressure changes. This helps improve energy efficiency, reduce balancing issues, and ensure reliable heating or cooling performance from the fan coil unit.
What is an FCU Valve?
An FCU Valve is a valve used in a fan coil unit system to control the flow of chilled or heated water. It helps the fan coil unit deliver proper heating or cooling based on system requirements.
How do I choose the right FCU Valve?
To choose the right FCU Valve, consider the fan coil unit size, flow rate, pressure requirements, connection type, installation space, and whether the system needs PICV, ABV 4-Port, or commissioning valve functionality.
