Product Description:

What is an RF Triple Offset butterfly valve

The RF flange triple eccentric butterfly valve is a high-performance fluid control valve, which adopts the RF flange connection mode and has the triple eccentric design. The valve rotates the disc to open and close the fluid, and its special design reduces the operating torque, improves the sealing performance and extends the service life of the valve. The design of the RF flange further enhances the sealing of the valve, ensuring stable and reliable operation in a variety of industrial environments. Suitable for high temperature, high pressure and corrosive media fluid control system, widely used in chemical, oil, natural gas and other fields.

How does the RF flange Triple Offset butterfly valve work

The working principle of the RF flanged triple eccentric butterfly valve is based on its unique design. In the closed state, the butterfly valve’s RF flange connection ensures a strong connection, while the three-eccentric design includes axial, radius and angular eccentricity, so that the butterfly plate position is three different eccentricities relative to the fluid flow axis. When the valve needs to be opened, the disc begins to rotate, and the three-eccentric design reduces operating torque at start-up while maintaining sealing performance. As the disc rotates, the RF flange ensures close contact with the valve sealing surface, preventing fluid leakage. In the fully open state, the disc is parallel to the fluid flow direction, allowing the fluid to pass freely. This design enables the RF, triple-eccentric butterfly valve to provide efficient fluid control for industrial applications with high temperature, high pressure and aggressive media.

RF flange Triple Offset butterfly valve product overview

1. RF flange connection
Using RF flange connection to ensure a firm connection between the valve and the pipeline. The RF flange design helps to improve sealing, making the valve suitable for processes requiring high sealing.

2. Three-eccentric design
The three-eccentric design includes three directions of eccentric axis, radius and Angle. This design reduces operating torque, improves start-up efficiency, and extends valve life. The disc of the valve maintains a stable sealing performance during rotation.

3. Fluid control accuracy
The valve can achieve fast and accurate fluid control, and is widely used in industrial processes requiring high-precision fluid control.

4. High temperature and high-pressure resistance
Suitable for high-temperature and high-pressure environment, such as petrochemical, electric power, metallurgy and other industrial fields. Materials and design allow the valve to operate stably under extreme conditions.

5. Leak-proof design
The RF flange and Triple Offset design together ensure excellent sealing of the valve in the closed state, effectively preventing fluid leakage.

6. A variety of material selection
The main components of the valve are made of corrosion-resistant and wear-resistant materials, such as stainless steel, alloy, etc., to meet the requirements of different media.

7. Widely used
It is widely used in chemical, oil, natural gas, water treatment and other industrial fields, especially for processes with strict fluid control requirements.

8. Optional operation mode
The valve can be equipped with manual operation, electric actuator and other operating devices to meet the needs of different systems.
