Reliable Automatic Flow Control Solution with Electric Actuator

Cair Valve is a trusted Motorized Butterfly Valve Manufacturer in India, providing reliable automatic flow control solutions for water, industrial, and process applications. Our motorized butterfly valves are designed with electric actuators to provide smooth operation, accurate flow control, and dependable shut-off performance.

A motorized butterfly valve combines a butterfly valve with an electric actuator, allowing automatic opening, closing, and flow regulation without manual effort. These valves are suitable for applications where frequent operation, remote control, and precise flow management are required.

What is a Motorized Butterfly Valve?

A Motorized Butterfly Valve is an electrically operated valve used to control fluid flow in pipelines. Instead of using a manual handle or gearbox, an electric actuator rotates the valve disc according to the required operation.

The actuator rotates the disc through a 90° quarter-turn movement:

• 0° Position: Valve fully closed

• 10° to 80° Position: Flow regulation and control

• 90° Position: Valve fully open

This simple rotating mechanism provides fast operation, efficient flow control, and reliable performance.

How Does an Electric Actuator Operate a Butterfly Valve?

An electric actuator operates by converting electrical energy into mechanical rotation. The actuator is connected to the valve shaft, which rotates the butterfly disc inside the valve body.

When a control signal is received, the actuator moves the disc to the required position. Limit switches provide accurate open and close positioning, ensuring safe operation and preventing unnecessary movement.

Electric actuators are available according to application requirements, including:

• ON/OFF operation

• Modulating flow control

• Different torque requirements

• Different voltage options

Working Principle of Motorized Butterfly Valve

The working principle of a motorized butterfly valve is based on the rotation of a disc inside the pipeline.

When the disc is aligned with the pipeline, maximum flow is allowed. When the disc rotates and blocks the pipeline, the flow stops completely. By controlling the disc position, the valve can regulate the flow according to system requirements.

The electric actuator makes the operation automatic, reducing manual effort and improving efficiency.

Types of Motorized Butterfly Valves

Cair Valve manufactures different types of motorized butterfly valves based on application requirements.

Wafer Type Motorized Butterfly Valve

Wafer type butterfly valves have a compact design and are widely used in water supply, HVAC, and industrial pipeline applications where space-saving installation is required.

Lug Type Motorized Butterfly Valve

Lug type motorized butterfly valves provide reliable isolation and are suitable for applications where pipeline maintenance and equipment separation are required.

Double Flanged Motorized Butterfly Valve

Double flanged butterfly valves are designed for larger pipelines where strong flange connections and heavy-duty performance are required.

Soft Seated Motorized Butterfly Valve

Soft seated butterfly valves provide excellent sealing performance and are commonly used for water, wastewater, and general industrial applications.

Metal Seated Motorized Butterfly Valve

Metal seated butterfly valves are suitable for high-temperature and demanding industrial applications where strong durability is required.

Manual vs Motorized Butterfly Valve

A manual butterfly valve requires physical operation using a handle or gearbox, while a motorized butterfly valve uses an electric actuator for automatic operation.

Motorized butterfly valves are preferred where:

• Frequent opening and closing are required

• Remote operation is needed

• Accurate flow control is important

• Automation is required

ON/OFF and Modulating Electric Actuator Control

Cair Valve provides motorized butterfly valves with two main control options:

ON/OFF Control

ON/OFF actuators are used when the valve only needs to operate between fully open and fully closed positions.

Modulating Control

Modulating actuators allow the disc position to be adjusted at different levels for accurate flow regulation.

Smart Automation Options for Motorized Butterfly Valve

Modern motorized butterfly valves can be integrated with smart operation systems for improved monitoring and control.

Cair Valve provides advanced options such as:

• GSM control

• Wi-Fi-based operation

• Remote valve operation solutions

These features help industries operate valves safely and efficiently from a convenient location.
