Butterfly Valves

Butterfly valves control the flow of a media, liquid, or gas. This is achieved using a rotating ball with a bore. These valves can effectively stop the media flow through the system. They are one of the most popular valves. The operation is effortless, reliable, has a long service life, and wide range of applications. They can either be operated manually, or electrically, or pneumatically. Depending on your application and the available actuation type, you can select the proper butterfly valve.

We supply variety of quality valves as below -

Valve types

These valves are available in diverse designs, suitable for specific applications and pressure ranges. They are generally categorized based on:

• Actuation method: Manual, Electric, or Pneumatic
• Disc closure design: concentric or eccentric
• Connection design

Actuation Methods

Butterfly valves can be operated manually by handle and gears or automatically by electric, pneumatic, or hydraulic actuators. These devices allow precise disc rotation to positions ranging from fully open to fully close. Different types of actuations are as below:

Manual Actuation

Manual actuated butterfly valves are inexpensive and easy to operate. The two standard manual methods are hand lever and gear.

Automatic Actuation

Power-operated actuators are a reliable method of controlling valves from a remote location. These actuators also make the rapid operation of larger valves possible. The three types of automatic actuators are as under:

• Manual ball valves: Utilize a lever to open or close the valve at a 90-degree turn.
• Electric ball valves: These valves have an electric actuator connected to the valve. It requires a voltage input, and the actuator will automatically open or close the valve.
• Pneumatic ball valves: These valves have a pneumatic actuator connected to the valve. It requires compressed air to open or close the valve automatically.
• Hydraulic ball valves: Requires hydraulic pressure to move a piston or diaphragm to open/close the valve.
