About Belimo HVAC Actuators and Control Valves

An actuator is selected on torque, on control signal and on what it must do when power is lost. Torque has to cover the damper area and blade seal friction or the valve close-off pressure, and an undersized actuator will appear to work at commissioning and stall against a dirty or pressurised damper months later. The control signal determines the type: an on-off actuator switches between two positions, a three-point actuator is driven open and closed by two contacts, and a modulating actuator follows a 0 to 10 V or 4 to 20 mA signal and reports position back. Fail-safe behaviour distinguishes a standard actuator, which holds position on power loss, from a spring-return actuator, which drives to a defined safe position, and this is not an option that can be added later. Fire and smoke damper actuators carry a thermal element and an approval that ties them to the damper assembly. Control valves are chosen by flow coefficient and close-off pressure, and a characterised control valve pairs a defined flow characteristic with the actuator.

Belimo HVAC Actuators and Control Valves in Saudi Arabia

Cooling dominates energy use in Saudi buildings, so damper and valve actuation is fitted in very large numbers. Air handling units, fan coil units, VAV terminal boxes, outside air and mixing dampers, chilled water coil valves and chiller plant isolation are the standard duties in office towers, hospitals, hotels, universities, airports and shopping centres across Riyadh, Jeddah and Dammam, and in the new developments at NEOM and along the Red Sea coast. Fire and smoke damper actuators are installed throughout life-safety systems and are subject to Civil Defence inspection, so replacement must preserve the approval on the damper assembly. Plant rooms and ceiling voids run hot, and actuators mounted above a hot deck or in an unventilated riser fail earlier than those in conditioned space. Local control transformer supplies are derived from a 380/400 V 60 Hz system, and actuator supply voltage must be confirmed against what is present at the terminal unit.

Ordering and lead time

Quote the Belimo type designation as printed on the actuator label, for example LM230A, GM24A or BF24-T, since the code carries torque class, supply voltage, control signal and fail-safe behaviour. When replacing a unit, state the damper area or the valve size and close-off pressure, the shaft diameter and length for a rotary actuator, the supply voltage available, and the control signal from the building system as on-off, three-point or modulating. Confirm whether spring return is required and to which position, because that is a different model rather than an accessory. For fire and smoke damper actuators, state the approval that the damper assembly holds, as a like-for-like replacement is normally required. Auxiliary switches and linkage kits are separate references. Items are sourced to order with a typical lead time of three weeks and delivered duty-paid to site.
