Lug-Style Butterfly Valve
Lug-style butterfly valves are usually composed of metal such as ductile iron or steel.
They feature threaded tapped lugs positioned on the valve flanges for bolt connections.
Lug-style butterfly valves are suitable for end-of-line service but a blind flange is always recommended.
Lug-style butterfly valves are manufactured to be compatible with either pneumatic or electric actuation.
Disc and seat material should be determined based on application and flow media.
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.
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.
Industrial Applications
Butterfly valves are used in a variety of industries, including:
Oil and gas
Chemical processing
Water and wastewater processing and transportation
Food processing
Pharmaceuticals
Manufacturing
Shipbuilding and shipyards
HVAC
