A flange type butterfly valve helps control how liquids or gases move in pipes. People use this valve when they want something strong and dependable. It can start, stop, or change the flow. The name comes from the flanges on both ends. These flanges let you bolt the valve between two pipes. This makes a tight seal and stops leaks. Many industries use this valve because it works well with pressure. It also handles many kinds of fluids.
Inside a flange type butterfly valve, there are some key parts:
Body: This is the main part that holds everything together. It is made from tough metals like stainless steel or cast iron.
Disc: This is a round plate inside the valve. When you turn the handle, the disc moves to open or close the flow.
Stem: This rod links the handle or actuator to the disc. It helps you move the disc easily.
Seat: This is a ring inside the valve body. The disc pushes against the seat to make a tight seal when closed.
Actuator or Handle: This is what you use to turn the valve. You can pick a manual handle, a gear, or an automatic actuator.
Tip: PIONEER’s flange type butterfly valves use strong materials and careful design. This means the valve lasts longer and works well in hard jobs.
The flanged connection makes this valve different from others. Each end has a flat, round flange with holes for bolts. You line up the flanges with the pipe flanges and bolt them together.

PIONEER’s flange type butterfly valve is special because it is built strong and checked for quality. You get a valve that keeps your system safe and working well, even in tough places.
You use a flange type butterfly valve to control how much fluid moves through a pipe. The main part that does this job is the disc inside the valve. When you turn the handle or actuator, the disc rotates around its axis. If you turn the disc so it stands straight up, it blocks the flow. If you turn it flat, it lets the fluid pass through. You can also set the disc at any angle between open and closed. This lets you adjust the flow rate with great accuracy.
Note: The disc in a flange type butterfly valve moves with very little friction. This makes it easy for you to operate, even when the valve is large or the pressure is high.
You can follow these simple steps to operate a flange type butterfly valve:
Check the Valve Position: Look at the handle or actuator to see if the valve is open, closed, or partly open.
Turn the Handle or Actuator: Move the handle or use the actuator to rotate the disc.
Adjust the Flow: Stop turning when you reach the flow rate you want. The disc will stay in place and keep the flow steady.
Secure the Position: Some valves have a locking device. You can use this to keep the valve from moving by accident.
Inspect for Leaks: After you set the valve, check the flanged connections. Make sure there are no leaks around the valve.
Here is a simple table to show what happens at each disc position:
Disc Position | Flow Status | Common Use |
|---|---|---|
0° (Closed) | No flow | Shut off fluid |
45° (Partial) | Some flow | Adjust flow rate |
90° (Open) | Full flow | Allow full passage |
You can choose from several actuator types to operate a flange type butterfly valve. Each type fits different needs:
Manual Handle: You turn this by hand. It works best for small valves or when you do not need to open and close the valve often.
Worm Gear Operator: This uses gears to make turning easier. You use this for larger valves or higher pressure systems.
Pneumatic Actuator: This uses air pressure to move the disc. It works well when you need fast or remote operation.
Electric Actuator: This uses an electric motor. You can control the valve with a switch or even a computer.
Hydraulic Actuator: This uses fluid power. It is strong and works well in heavy-duty jobs.
Tip: You should pick the actuator that matches your system’s size, pressure, and how often you need to operate the valve.
