Reliable Automatic Flow Control Solutions with Electric Actuators
Cair Valve is a trusted Motorized Butterfly Valve Manufacturer in India, offering high-quality automatic butterfly valves for water treatment, wastewater, HVAC, irrigation, power plants, and industrial process applications. Our motorized butterfly valves are designed to provide smooth operation, reliable shut-off, and precise flow control using advanced electric actuators. Every valve is manufactured and tested to deliver long service life, low maintenance, and dependable performance.
What is a Motorized Butterfly Valve?
A motorized butterfly valve is a butterfly valve operated by an electric actuator instead of a manual lever or gearbox. The actuator rotates the valve disc by 90° (quarter-turn) to open, close, or regulate the flow of liquids and gases. This automatic operation eliminates manual effort while improving process efficiency and operational safety.
How Does an Electric Actuator Operate a Butterfly Valve?
The electric actuator converts electrical energy into rotary motion. When it receives an electrical signal, the actuator rotates the valve shaft, which turns the butterfly disc to the required position. Built-in limit switches ensure accurate positioning for fully open, fully closed, or intermediate positions during modulating service.
Working Principle of a Motorized Butterfly Valve
The butterfly disc is mounted on a central shaft inside the pipeline. When the disc is parallel to the flow direction, the valve is fully open and allows maximum flow. As the actuator rotates the disc, the opening gradually reduces to regulate flow. At 90°, the disc is perpendicular to the pipeline, creating a tight seal that stops the flow completely.

Types of Motorized Butterfly Valves
Wafer Type Motorized Butterfly Valve
Ideal for compact pipeline installations where space is limited. It offers reliable sealing and economical installation for water and industrial services.
Lug Type Motorized Butterfly Valve
Designed for dead-end service and applications requiring easy removal of downstream piping without disturbing the upstream line.
Double Flanged Motorized Butterfly Valve
Suitable for larger pipelines where rigid flange connections and high mechanical strength are required.
Soft Seated Motorized Butterfly Valve
Uses resilient seats such as EPDM or NBR to provide bubble-tight sealing for water, wastewater, HVAC, and general industrial applications.
Metal Seated Motorized Butterfly Valve
Designed for high-temperature, abrasive, and demanding industrial applications where metal-to-metal sealing offers greater durability.
Manual vs Motorized Butterfly Valve
Manual butterfly valves require an operator to open and close the valve using a lever or gearbox. Motorized butterfly valves perform the same operation automatically through an electric actuator. They are ideal for remote locations, frequent operation, and applications requiring precise control without manual intervention.
ON/OFF and Modulating Electric Actuators
We offer motorized butterfly valves with two actuator options:
ON/OFF Electric Actuator – Opens or closes the valve completely.
Modulating Electric Actuator – Precisely positions the valve disc at any required angle for accurate flow regulation.
Smart Automation Solutions
For advanced automation projects, Cair Valve offers electric actuators with GSM, Wi-Fi, and remote-control capabilities. These solutions help operators monitor and control valves from remote locations, improving operational efficiency and reducing downtime.
