Butterfly valve seal ring butterfly valve dn250 valve with actuator
Butterfly Valves are designed to regulate flow, but with limited control capability. Butterfly valves are easily operated by rotating a handle 90 degrees. It consists of a metal disc in the body of the valve which is positioned perpendicular to the flow in the closed position. Regulation of liquid flow can be allowed through intermediate rotations. Butterfly valves are configured to operate electronically, manually or pneumatically.
A Butterfly valve is a quarter-turn rotational motion valve, that is used to stop, regulate, and start flow.Butterfly valves are easy and fast to open. A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the hand wheel by gears is connected to the stem. This simplifies the operation of the valve, but at the expense of speed.
The application of butterfly valves
They can be used for a broad range of applications within water supply, wastewater treatment, fire protection and gas supply, in the chemical and oil industries, in fuel handling systems, power generation etc. These valves can be operated by handles, gears or actuators according to specific needs.
Applications:
• Butterfly valves can be used in pharmaceutical, chemical, and food processing services.
• They are used for corrosive liquids at low temp and pressure.
Typical applications of Butterfly valves
A Butterfly valve can be used in many different fluid services and they perform well in slurry applications. The following are some typical applications of Butterfly valves:
• Cooling water, air, gases, fire protection etc.
• Slurry and similar services
• Vacuum service
• High-pressure and high-temperature water and steam services
