A Butterfly valve is a quarter-turn rotary motion valve, that is used to stop,
regulate, and start the flow. Butterfly valves are a quick open
type. A 90° rotation of the handle can completely close or open the
valve. Normally, they are used in systems where a positive shut-off
is not required. In this article, you will learn about following
types of Valve.
- Wafer Type
- Lug Style Type
- Flanged Type
- Butt Welded Ends Types
- Zero offset
- Double Offset
- Triple Offset
Large Butterfly valves are usually equipped with gearbox type
actuator, where the handwheel is connected to the stem via a
gearbox. This will reduce the force but at the same time reduce the
speed of the operation. This type of valve should be installed in
the open position. If the valve is closed during installation, the
rubber seat will wedge against the valve disc and make it difficult
to open.

Types of Butterfly Valves Based on Body Construction
Based on the type of ends of the body butterfly valves are
available in following types.
Both Flanged Ends
Wafer Type Ends
Lug Type Ends
Butt Welded Types Ends
Water Type
The wafer body is placed between pipe flanges, and the flange bolts
surround the valve body.
A wafer type butterfly valve is easy to installed but it cannot be
used as an isolation valve.
Seat Types
Butterfly valves can be metal-to-metal seated, soft seated, or with
a fully lined body and disc.
The first image is of a soft seated fully lined body and disc
valve. Second, is a soft seat with metal disk
and the third is metal to metal seat type valve.
