Wafer Butterfly Valve:Electric soft seal adjustment has simple structure, small volume, light weight.And only need to switch 90.It can be opened and closed quickly with simple operation. At the same time, the reading door has good fluid control characteristics.When the wafer type butterfly reading is in the fully open position, the butterfly plate thickness is the only resistance when the medium flows through the reading body, so the pressure drop generated through the reading door is very small, so it has good flow control characteristics.Widely used in municipal water engineering, fire, air conditioning, environmental protection, food, light industry, electric power, oil, paper and other automatic control systems.
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.
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.
