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.

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.
