Sanitary Butterfly Valves
The sanitary butterfly valve adopts standard mirror polishing, and the smooth surface ensures cleanness, no medium accumulation area, and no potential pollution. Quick disassembly and assembly of the valve makes the valve opening and maintenance quick and easy, and shortens the process downtime. Hygienic, automatic or manual butterfly valves are widely used in beer, beverages, dairy products, fruit juices, pharmaceuticals, bioengineering and other fields. Sanitary butterfly valve is also called as hygienic butterfly valve which is a type of flow control device, used to make a fluid start or stop flowing through a section of pipe.

What is a butterfly valve?
A Butterfly valve is a quarter-turn rotary motion valve with advantage of low pressure drop and high-pressure recovery.
What are butterfly valves used for?
Butterfly valves are used to stop, start, and regulate fluid flow.
What is a rubber lined / concentric butterfly valve?
Concentric butterfly valves also known as ‘resilient seated’ butterfly valves are suitable for a wide range of applications such as cooling water, chemicals, brine, oil mud, hydrocarbons, wastewater, firewater, seawater, natural gas and flare gas amongst many others. The stem is centred in the middle of the disc and the disc centred in the valve body. The disc is constantly in contact with valve seat. Seats can include EPDM, NBR, Viton, Silicon, Teflon, Hypalon and neoprene.
Are butterfly valves bidirectional?
Butterfly valves can be bi-directional but often have a preferred flow direction. It’s strongly recommended to install the valves in the preferred flow direction, as it will extend the valve’s life span and will also lower the operating torque.
High-performance butterfly valves for hydrocarbon service generally do not have a preferred flow direction and are bi-
directional.
What is a lug type butterfly valve?
The lugged wafer design, butterfly valve is held in place between two pipe flanges by bolts that join the two flanges and pass-through threaded holes (or lugs) in the valve’s body.
This design type can be used for dead-end service.
What is a wafer type butterfly valve?
The wafer type butterfly valve, also known as non-lugged is sandwiched between two pipeline flanges. It may sometimes have unthreaded guiding holes for ease of installation.
What is a flange type butterfly valve?
Flange type or Double Flanged Butterfly valves have two flanges - one either end as opposed to lug type which has one flange in the center. Flange type have a larger face to face than wafer or lugged. These can be used for dead end service.
