Flexible, reliable and compact: what’s needed in today’s valve actuators
U
sers of large commercial buildings such as universities, schools and hospitals expect the temperature, heating and cooling within
the property to be consistent and deliver comfort without unwanted surprises. Building managers, therefore, face the need for
system robustness, optimised running costs and futureproofing for long-term and effective HVAC performance. At a time when a standard hospital will face
average annual electricity bills of up to £431,000*, every efficiency gain has the potential to contribute to overall cost savings. There are many components that can support an effective heating and cooling solution, and
In commercial buildings, the ability to effectively control hydronic valves is important to ensuring individual rooms and zones are consistently heated and cooled to a comfortable temperature. As building operators demand better efficiencies in the management of their energy costs and systems, contractors must be prepared with flexible controls that keep downtime and commissioning costs to a minimum. Andrew Stokes-Roberts, senior account manager at Resideo, explains the role water actuators play and what to look out for

1. Ease of system servicing and use Look for valve actuators that are compatible with a wide range of valves and offer simplified installation procedures, set up and servicing. This will keep commissioning time to a minimum, help servicing to be completed quickly and reduce the potential for system downtime. Also, look for easy access to control signal settings and the ability to use a rotary signal selector for speed and efficiency.
a water valve actuator is one of them. Ease of installation, consistent performance, flexibility, and cost-effectiveness are key priorities for building management operators, and installers can help support such aims through the specification of best- practice HVAC valve actuators. Valve actuators, play a crucial role in controlling
the flow of water in various systems by converting energy to provide precise control and therefore lower energy consumption. An engineered mechanism that controls the opening and closing of a hydronic valve, an actuator regulates the flow of water for heating and cooling systems. It converts a control signal from the BMS into mechanical motion, enabling the valve to adjust the water flow as required to suit the building’s need and demand. The building management system controls the actuator by dictating how open or closed the valve needs to be to optimise the building’s heating system performance and efficiency for the very best user comfort and smooth running.
Designed for today’s needs
Developments in valve actuator design and functionality are now delivering many advantages with regard to installation, ongoing system maintenance needs and overall system optimisation, helping contractors approach building management customers with a list of tangible benefits.

2. Compact design Today’s small valve actuator designs provide installation advantages without compromising performance. The flexibility to be installed in a variety of locations can provide practical benefits in terms of time and cost savings.
3. Energy control Actuators will help drive effective control and help achieve energy consumption objectives as part of a building’s holistic heating and cooling energy control system. Utilising advanced control technology can offer operational advantages, including potential energy savings, subject to system design and usage. Resideo has introduced a new range of linear
valve actuators specifically designed for Building Management System (BMS) applications. The actuator has been engineered to help simplify
system maintenance and optimise the performance of hydronic valves in commercial heating and cooling installations through precision-controlled motors. It will be available across Europe from Summer 2025. Control options include modulating, three-point and on/off, 24V AC and DC and 180N and 300N actuator closing force. The range is IP54 rated and comes with a five-year warranty**.
