Double Flanged Butterfly Valve

Description

Double Flanged Butterfly Valve

A double flanged butterfly valve is a robust quarter-turn valve designed for reliable flow isolation and control in industrial piping systems. Its flanged construction provides a secure connection between the valve and pipeline.

The design is suitable for applications requiring dependable shutoff, easy operation, and efficient flow management. Unitek Valves manufactures and supplies butterfly valves for various industrial requirements.

Double Flanged Butterfly Valves for Industrial Applications

Double flanged butterfly valves are widely used in water treatment, oil and gas, chemical processing, petrochemical, power generation, HVAC, and general industrial systems.

An industrial double flanged butterfly valve can be operated manually or fitted with a suitable actuator. Its compact quarter-turn operation allows quick opening and closing compared with many conventional valve designs.

Material Options

A stainless steel double butterfly valve provides good corrosion resistance and can be suitable for demanding process environments.

Ductile iron double flanged valves offer strength and durability while providing a practical solution for many water and utility applications.

Cast iron double flanged valves are commonly selected for suitable low-to-medium pressure services where economical construction is important.

For demanding industrial applications, a carbon steel double flanged butterfly valve can provide high mechanical strength and durability.

High-Pressure and High-Temperature Applications

A high pressure double flanged valve can be selected for systems operating under elevated pressure conditions. The appropriate pressure rating, body material, disc material, and seat design should be determined according to the application.

For elevated-temperature services, a high temperature double flanged valve can be selected with suitable body, seat, and sealing materials.

Seat Options

A resilient seated double flanged butterfly valve uses an elastomeric seat to provide reliable sealing for compatible applications. These valves are commonly used in water and utility systems.

A rubber lined double flanged butterfly valve provides a protective lining suitable for applications where corrosion resistance and media compatibility are important.

Water and Industrial Applications

A water double flanged butterfly valve can be used in water treatment plants, distribution systems, cooling-water lines, irrigation systems, and other compatible services.

The correct valve should be selected based on fluid characteristics, pressure, temperature, pipeline size, and required sealing performance.
