This valve has a circular plate which rotates around an axis. Its closing mechanism consists of a rotating disc. It is quite similar to the ball valve. Butterfly valves are inexpensive as compared to other valves. They also require lesser support as they are light weighted. A disc is located in the middle of the pipe through which a rod is passed. This rod meets the actuator located on the outer side of the valve. The disc can be turned parallel or at 90° to the flow by rotating actuator. It stimulates pressure drop because it is always existing in the flow. Get best quality butterfly valves at Blackhawk supply through our website.
It comes under the category of quarter-turn valves. Whenever the disc is in the position of a quarter turn, the valve is either completely open or completely closed. The metal disc which is placed above a rod is in the form of a butterfly. On closing the valve, the disc turns in a way which blocks the passage of fluid. The disc is in the position of a quarter turn when the valve is open. This allows the passage of fluid. Butterfly valve comes in two types. Each is suitable for various pressure. Zero-offset butterfly valve has the lowest pressure range. Whereas high-pressure mechanism is handled by a double offset butterfly valve. However triple offset butterfly valve is best suited for extremely high-pressure design.
Types of butterfly valves
- Concentric butterfly valves – it consists of a resilient rubber seat and a metal disc
- Double eccentric butterfly valves- (double offset valves) it comprises of different materials for the disc. Also, the seat is made from various materials
- Triple eccentric butterfly valves- (triple offset butterfly valves)- their seats are laminated or made with a solid metal design
