Belimo: The World Leader in HVAC Actuators and Control Valves

Belimo Holding AG, headquartered in Hinwil, Switzerland, is the global market leader in the development, production, and marketing of actuator solutions for controlling HVAC systems. Founded in 1975 by Werner Arn, Belimo has grown to employ over 2,200 people with annual revenue exceeding CHF 800 million. The company holds the number one global market position in HVAC damper actuators, control valves, and sensors—a position built on 50 years of continuous innovation in building climate control technology.

Belimo's focus is exclusively on HVAC—they don't manufacture process control valves, industrial actuators, or general-purpose sensors. This singular focus has made them the uncontested expert in air and water-side HVAC control, with products installed in millions of buildings worldwide.

Belimo Products Available Through RAZZ Middle East

Damper Actuators

Belimo damper actuators control air dampers in air handling units, VAV boxes, and ductwork. AF/NF/LF series spring-return actuators provide fail-safe damper positioning for outside air, exhaust, and fire/smoke dampers. AM/NM/LM series non-spring-return actuators handle modulating and on-off damper control. Torque ratings from 0.8 Nm (small zone dampers) to 240 Nm (large industrial dampers) cover every application. NKQX24-MFT quick-mount actuators simplify installation on standard dampers.

Control Valves

Belimo characterized control valves (CCV) combine valve body and actuator in a single assembly with factory-tested performance curves. Pressure-independent characterized control valves (PICCV) automatically maintain design flow regardless of pressure variations—eliminating manual balancing and ensuring consistent comfort in multi-zone HVAC systems. 6-way valves simplify changeover between heating and cooling in two-pipe chilled/hot water systems.

Butterfly Valves

Belimo butterfly valves with actuators serve large-diameter chilled water, condenser water, and hot water applications from DN50 to DN600. Wafer-style installation reduces weight and space compared to flanged globe valves. Electronic fail-safe actuators provide spring-return on power failure.

Sensors

Belimo manufactures a comprehensive range of HVAC sensors. Temperature sensors (duct, immersion, outside air, room) with NTC, Pt1000, and 4-20mA outputs. Humidity sensors for room and duct applications. CO2 sensors for demand-controlled ventilation. Differential pressure sensors for filter monitoring and airflow measurement. The Belimo Energy Valve combines a 2-way valve with flow, temperature, and energy measurement—providing real-time IoT-connected energy data for each HVAC zone.

Belimo in Saudi Arabia

Belimo products are critical to Saudi Arabia's building HVAC industry. In a country where cooling represents over 70% of building energy consumption, precise HVAC control directly impacts energy costs and occupant comfort. Belimo damper actuators control outside air intake, zone airflow, and exhaust in commercial buildings, hospitals, hotels, malls, and office towers across the Kingdom. Belimo control valves and PICCV technology optimize chilled water distribution in large district cooling and building chiller plant systems.

Saudi Green Building standards and Vision 2030 energy efficiency requirements drive adoption of Belimo's energy-efficient control technologies. The Belimo Energy Valve provides the IoT-connected zone-level energy measurement that building managers need to optimize HVAC energy consumption in new smart buildings.

Frequently Asked Questions

What Belimo products are most commonly ordered?

AF/NF spring-return damper actuators, characterized control valves (CCV), and temperature/humidity sensors are our highest-volume Belimo products in Saudi Arabia.

What is a PICCV and why is it important?

A Pressure-Independent Characterized Control Valve automatically maintains design flow regardless of system pressure changes. It eliminates manual balancing and ensures consistent comfort—particularly valuable in large Saudi HVAC systems where pressure variations are common.

Does Belimo work with all BAS systems?

Yes. Belimo actuators and valves support standard HVAC control signals (0-10V, 4-20mA, 2-10V) and communicate via BACnet, Modbus, and MP-Bus protocols, making them compatible with all major BAS platforms including Metasys, Desigo, and Honeywell.

What savings should I expect?

Standard Belimo products show 15–25% savings versus local Saudi pricing with project discounts for large building orders.
