Butterfly valves are quarter-turn valves that use a disc-shaped element to regulate flow. The disc is perpendicular to the direction of flow when closed and parallel when open, and can be operated by a lever, handwheel, pneumatic actuator, or electric actuator.
These valves find application in chemical processing, خوردنی و آشامیدنی, دارویی, water treatment, and HVAC industries, بین دیگران.
Farpro Valve manufacturers provide a wide range of general-purpose and specialty butterfly valves to numerous industries and businesses. We prioritize the best quality of butterfly valve products while keeping sales prices as low as possible.

General Types of Butterfly Valve Construction
- Valve Body: The body of a butterfly valve is a circular or oval tube containing the valve disc and seat. The valve body can be made of various materials, such as cast iron, آهن انعطاف پذیر, فولاد کربن, فولاد ضد زنگ, و پلاستیک.
- Valve Disc: The valve disc of a butterfly valve is attached to the stem and rotates around the stem to control flow. The disc can be made of various materials such as cast iron, فولاد ضد زنگ, aluminum, و پلاستیک. The shape of the disc can be round, oval, or even rectangular.
- ساقه: The stem of a butterfly valve connects the disc to the actuator. It transmits the torque from the actuator to the disc, causing it to rotate. The stem can come in different lengths and materials, مانند فولاد ضد زنگ, فولاد کربن, or aluminum.
- Valve Seat: The seat of a butterfly valve is a ring-shaped element mounted inside the valve body. It provides a sealing surface for the valve flap to close. The seat can be made of various materials, such as rubber, PTFE, metal, or graphite.
- Actuator: The actuator of a butterfly valve is responsible for controlling the rotation of the butterfly blade. The actuator can be manual, pneumatic, or electric. Manual actuators use a lever or handwheel to operate the valve. Pneumatic actuators use compressed air to rotate the disc, while electric actuators use an electric motor to drive the valve.
Classified by Actuation Method
Electric Actuated Butterfly Valve
The electric actuated is a modern, versatile method of driving butterfly valves. It involves an electric motor that rotates the valve disc through a series of gears or a direct drive mechanism.
The electric drive allows precise control of the valve position and can be operated remotely using a control panel or computer.
It is typically used in applications that require frequent adjustments, such as water treatment and HVAC systems.
Pneumatic Butterfly Valves
Pneumatic actuation is a method of actuation for butterfly valves that involves the use of compressed air to rotate the valve disc.
It is typically used in industrial applications that require high torque and precise control, such as the chemical processing and oil and gas industries.
Manual Butterfly Valves
Manual actuation is the most basic method of actuation for butterfly valves. It involves a lever or handwheel that is rotated manually to open or close the valve.
It is simple, قابل اعتماد, and cost-effective, making it the best choice for small-scale applications that do not require frequent adjustments. Manual actuation is often used in residential and commercial buildings, where butterfly valves are used for water control.
Geared Butterfly Valves
Gear actuation is a popular method of butterfly valve actuation. It involves a gearbox that is connected to the valve stem and rotates the disc.
The gear drive provides precise control of the valve position and allows for a higher torque output than a manual drive.
It is typically used in industrial applications that require high torque and precise control, such as the chemical processing and oil and gas industries.
