Introduce

 

Butterfly valves are quarter turn valves ideal for on/off or modulating flow operations.

This valve is rated for 16 bar and is operated by hand, but can be used with an actuator (ISO 5211 F05).

The nominal diameter is 50 mm (2 inch) and has a wafer type flange. The Cast iron (GG25) housing,

stainless steel disc and NBR seal make it durable and allows for a media temperature between 5°C and 85°C.


Epoxy paiting suitable for drinking water applications.

 

Short body flanged butterfly valves are the new “state of the art” butterfly valves available on the market, with

a very compact design and various materials of constructions, they can be applied in several plants. Compatible

with BS, DIN and ANSI flanges, the short body flanged butterfly valves have the rubber liner vulcanized on the

body of the valve, allowing strong and reliable tightness, as well as the O ring cast on the body, that prevents any

need of gaskets. Short body flanged butterfly valves are manufactured as centric type disc, they can stand both

directions of fluid and are maintenance-free. The body, not in contact with the fluid, can be lined with EPDM, BUNA,

PTFE, Neoprene or Viton: in this way we can apply these butterfly valves to any plant and for every medium, simply

mounting the suitable disc in ductile iron, stainless steel 304 or 316, Al-Bronze C95400. Such valves can be installed

in any position. Short body flanged butterfly valves come reducing gear and handwheel (standard execution), pneumatic

operator with single or double effect, electric actuator on request.

 

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.

Pros

  • The hand operation allows for easy operation and understanding.

  • Relative low torque to switch position compared to ball valves.

  • High Kv-value because fluid can flow in straight line.

  • It has a small construction length in relation to the 50 mm (2 inch) diameter compared to a similar size ball valve.

  • It can be used for a wide array of fluids and gases.

  • Suitable for viscous media.

  • Remove the squeeze lever to mount an actuator thanks to the ISO 5211 flange.

 

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.
