SS316L 1" 150LB Flanged type Stainless Steel Wafer Butterfly Valve

 

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.

 

Lug Style

 

The lug body has protruding lugs in the periphery of a body that provides passage to bolt holes that match with those in the flanges.

 

Flanged Type

 

In this types, the body has flanged that match with pipe flange dimension.

 

Butt Welded Ends Types

 

This types of ends are used in high-pressure services and it directly welded to the pipe.
